南昌锦灵网络科技有限公司 (“we”) operates AI Pocket Book and processes personal information for its app, account services and related website functions. We do not provide ads, a public community or remote push notifications, and do not sell your personal information. Read this policy before choosing network and account features.
1. Contact
Support, privacy, complaints and minor protection: support@jinlingai.tech. Address: Room 803, Floor 8, Comprehensive Building, B-07 Changnan Industrial Park, Qingyunpu District, Nanchang, Jiangxi, China. Website: https://aipocketbook.cn/ . Me—Settings provides this policy, the personal information and third-party lists, permissions and account management.
2. Information and purposes
Basic operation and security: the app does not initiate network requests before your first privacy choice. After you choose network features, our services receive IP addresses, request times, app version, platform, language, necessary request identifiers and security state for configuration, connections and abuse prevention. App-instance identifiers support sessions and synchronization, not collection of IMEI, IMSI or advertising identifiers. Website visits create necessary network information; its sample exercise does not create a study account or use third-party tracking scripts.
Accounts: phone numbers, passwords or verification codes you enter, user IDs, app-instance/session information, masked phone hints, age declarations, consent versions and security events support login, binding, recovery and audits. SMS providers and carriers process numbers when sending requested codes; identity matching uses number digests. Passwords are stored as salted one-way derived values, not plaintext. Codes are time-limited and attempt-limited; ordinary logs do not record passwords or codes.
WeChat authentication and initial profile (supported Android versions): only after you explicitly request WeChat login, binding or security verification and authorize it in WeChat does our server process a one-time code, random verification state, OpenID and UnionID when available to verify identity and associate accounts using a digest. Under that authorization, our server may also retrieve your nickname and avatar URL from WeChat. Available nickname and avatar data is adopted as the initial profile only when that authorization creates a new account. Login, binding or security verification for an existing account does not overwrite its nickname or avatar. Avatars are fetched only from trusted official WeChat image addresses, validated and processed, then copied to our private avatar storage. If optional profile data is absent or unavailable, default profile values are used without blocking successful identity verification. You can later edit your profile. We do not send phone numbers or learning content to WeChat. Codes and WeChat access tokens are not written to ordinary logs or persistent mobile storage. You can revoke authorization in WeChat settings, use phone login or manage the association in our account-security settings.
QQ authentication (supported Android versions): the QQ Connect SDK initializes and checks QQ/TIM installation only after you read the relevant privacy notice and explicitly choose QQ login, binding or security verification. It handles the access token, expiry, OpenID and local correlation state following your authorization in QQ. Our server verifies the token and its application with QQ and associates an identity digest with your account. Available QQ nickname/avatar may initialize a newly registered profile; an existing profile is not overwritten. You may edit your profile, use phone login or manage account associations. Cancellation does not complete login. Tokens are used for verification and are not written to our ordinary logs or persistent account storage. We do not send your phone number, questions, answers or library to QQ. The provider is Shenzhen Tencent Computer Systems Company Limited. Device model supports SDK compatibility and diagnostics; networking involves IP and network status. See the third-party list for details and revocation options.
Profile: we process nicknames and avatars you voluntarily confirm, or the initial nickname/avatar adopted during authorized WeChat registration as described above. Photos you select are uploaded only after cropping and confirmation, not on cancellation; the entire photo library is not read. You can edit your nickname and avatar in your profile.
Study and synchronization: private books, questions, answers, notes, favorites, plans, attempts, times and review progress support storage, offline learning, statistics and cross-device synchronization. Local copies are account-isolated; synchronized data is stored on our servers. We do not publish your library or create public rankings from it.
AI and uploads: when you add reference material or request generation, questions, grading or lookups, we process necessary topics, book/author details, instructions, selected files/URLs, metadata, extracted text, questions, answers and context. Reading and parsing begin when you add material, before you press Generate. After you confirm the AI notice, necessary images, scanned pages and diagrams are converted and resized, then sent with relevant text to Qwen in Alibaba Cloud Model Studio's Beijing region to recognize text, interpret diagrams and organize the material. Links you provide are used to read publicly accessible content without bypassing login or verification challenges. We send only the selected material needed for that processing, not automatically your phone number, credentials or entire library, and do not scan other device files. Bundled pocket-book covers are static app resources. Originals and extraction results use our private storage under the retention rules below.
Feedback and reports: categories, descriptions, chosen screenshots, optional contacts and handling records support responses, content safety and rights protection. Do not include unrelated information about others.
Optional statistics are off by default. Only your opt-in and enabled product configuration allow limited feature events, without original questions or complete study content. You can disable this without affecting learning.
3. Permissions and system features
Speech input for explanations, answers or question notes starts at your request. Sign in, confirm the speech-to-text notice and allow microphone access; the Mini Program also requests the privacy authorization required by WeChat. A recording lasts up to three minutes. Our server forwards that recording to Qwen-ASR in Alibaba Cloud Model Studio's Beijing region, operated by Alibaba Cloud Computing Co., Ltd. and the applicable Model Studio operator. It does not attach question answers, your phone number or your entire library.
In Teach the AI, recording is transcribed in the background. Before submission, the text stays in the current account's local explanation draft for recovery and submission. It is not shown on the explanation, feedback or history screens and cannot be edited. Typed input has a separate draft; switching input methods does not merge them. Ordinary short-answer questions and question notes show the transcription for you to review and edit. Explanations and answers are assessed only after you submit them. Voice notes record your study thoughts; only text you choose to save becomes a question note and syncs under the existing rules. Voice notes are not graded. Finishing a recording or transcription does not submit an answer or save a question note. The Mini Program study page may keep an unsaved note draft on this device so you can return to edit it; this draft does not sync as a saved note.
The app clears temporary recordings after successful transcription, cancellation or leaving the page. Failed recordings remain only on that page for up to five minutes for retry. The Mini Program deletes the recording file after reading it. Failed audio remains only in that page's memory for up to five minutes for retry and is cleared after successful transcription, cancellation, leaving the page or changing accounts. Recordings are not included in learning-data synchronization. Our server forwards audio during request processing without writing it to databases, object storage or business logs. Encrypted transcripts are cached for up to five minutes; duplicate-request digests and necessary security state last up to 24 hours. Explanations and answers you submit, and note text you choose to save, are retained under the rules for those learning records and notes. Alibaba Cloud handles necessary call records under its service terms and legal obligations. You can use typed input instead. Cancellation cannot recall data already sent.
Notifications are used only for local study reminders you set; the boot-completed broadcast restores those reminders.
Domestic Android overlay permission and foreground services run only for study overlays you enable, with a visible notification and exit control. They do not use accessibility or screen recording to observe other apps. System pickers return only selected files/photos. We do not request contacts, precise location, call logs, SMS-reading or all-files storage permission. Revoke permissions in device settings; only dependent features are affected.
4. Third parties and disclosure
Tencent Cloud provides our mainland-China hosting and private COS storage for necessary service data. When SMS verification is available and you request it, Tencent Cloud SMS and carriers process the number, verification message and delivery state for authentication, not marketing. This is a server API, not an embedded SMS-reading SDK.
Alibaba Cloud Model Studio in Beijing provides Qwen text services and interpretation of reference-material images. See the third-party and AI notices for operators, data, purposes, triggers and policy links. Separate confirmation is required before first use and again before the next relevant AI use after the notice changes. Adding reference material may trigger this AI processing; refusal leaves manual questions and ordinary learning available. Speech transcription uses the Beijing Model Studio service described in the voice notice.
Android WeChat authentication uses WeChat Open SDK from 深圳市腾讯计算机系统有限公司. It initializes and checks WeChat installation only after your privacy choice and explicit use. The third-party list explains data, purposes, methods and revocation; its rules are at https://support.weixin.qq.com/cgi-bin/mmsupportacctnodeweb-bin/pages/RYiYJkLOrQwu0nb8 . Users aged 14–17 should obtain written guardian consent before using WeChat SDK features. Android QQ authentication is described above and in the third-party list (https://wiki.connect.qq.com/qq互联sdk隐私保护声明). Apple login and WeChat or QQ login on iOS are not yet enabled; their activation requires updated disclosures and necessary consent. Domestic Android channels offer WeChat checkout through Hupijiao (Xunhu) only when you select a paid product and explicitly confirm payment. Our service and the payment providers process the necessary order and product identifiers, amount, currency, in-app account association identifier, transaction identifiers, and payment or refund status to complete and verify transactions, deliver benefits and provide after-sales support. We do not send questions, answers, notes or phone numbers to payment providers. Current Android memberships renew manually without automatic debits. App Store purchases on iOS process necessary product, account association and Apple-signed transaction information only when the platform feature, products and production configuration are available and you explicitly confirm a purchase, for verification and restoration of benefits. Unavailable or unconfigured channels do not initiate real transactions. Our product does not read bank-card numbers, payment passwords or payment-platform login credentials. Third-party checkout and payment platforms handle information you provide on their pages under their own rules; the third-party list identifies the providers, data and relevant policies. We provide personal information to others only on a valid legal basis, such as requested services, legal obligations or valid authorization, and do not publish it. Entrusted processing is subject to agreed scope and safeguards; separate consent is sought when legally required. Organizational changes require appropriate notice and continued protection obligations.
5. Location and retention
Our servers, databases, storage and backups are deployed in mainland China. The production API is https://api.aipocketbook.cn . Model Studio text calls and reference-image interpretation use Beijing; other recipients' rules are listed separately. If changes require cross-border provision, applicable notification, separate consent and other legal procedures must be completed first.
Account, profile and synchronized study data is retained as necessary for continuing service. You may delete content or close your account. Deleted books have a seven-day recovery window before cleanup. Account closure has a cancellable seven-day cooling-off period, followed by deletion or anonymization of associated data.
Once you confirm an account-closure request, all existing login sessions are invalidated and the client signs out. During the seven-day cancellation period, you may verify your identity again, but the restricted session can only view closure status, cancel closure or sign out. It cannot read learning data, export content or perform other business operations. Cancelling closure restores normal use. After the period ends, associated data is deleted or anonymized under the Privacy Policy; legally retained information remains limited to the required purpose and period.
Codes expire after five minutes and cannot authenticate after expiry, consumption or locking. Necessary challenge-security state follows cleanup rules. Uploaded originals and extraction results not used in a generation task become eligible for cleanup after 24 hours. Originals, extraction results and intermediates used by a task enter asynchronous cleanup after completion, cancellation or final failure; cleanup errors are retried. AI interpretation results cached during material preparation to avoid repeat processing become eligible for periodic cleanup 24 hours after that interpretation completes. Material summaries associated with a generation task are cleared when the task ends. Necessary duplicate-request digests, billing and security audit records are retained for their respective purposes, without using them to retain material text long term. Logs, audits, rights requests and backups are restricted to necessary security, recovery, dispute and legal retention; network security logs are subject to the statutory minimum of six months. Backups are not used to resume ordinary processing of lawfully deleted accounts; recovery must respect deletion records.
When law requires continued storage or deletion is temporarily technically impossible, processing is restricted to storage and necessary security until the requirement or obstacle ends. Providers' lawful delivery/model-call records follow their applicable terms and obligations. We can assist with requests but do not promise immediate erasure of every copy.
6. Your choices and rights
Edit your nickname/avatar in account profile; manage phone, password and sessions in account management; edit/delete books and export learning data through About. Disable optional analytics, speech, reminders and overlays through the relevant settings.
Request closure in account management or at https://aipocketbook.cn/account-deletion . The web route verifies identity using available account methods; contact support if you cannot use it. Closure is not conditional on purchasing, unnecessary information or unreasonable steps.
For access/copy, correction/deletion, withdrawal, explanations or complaints, email support@jinlingai.tech. We aim to respond within 15 working days, verifying only proportionate identity information. If we cannot comply, we explain why and available remedies. Withdrawal does not invalidate earlier processing based on valid consent. Statutory complaint and court remedies remain available.
7. Minors
The product is for ages 14 and above. Users aged 14–17 should use it with guardian guidance. Children under 14 must not register or submit information. Guardians can report improperly processed information; we will verify and lawfully stop processing, delete or take other protective action.
8. Security and changes
We use HTTPS, access controls, account isolation, private storage, log redaction and backups, with staff access limited by duties. No system is absolutely risk-free. Incidents trigger lawful remediation, notification and reporting.
Material changes to purposes, methods, data types or recipients are disclosed through policy updates and appropriate prompts, with renewed consent where required. You can read the current policy in settings and on the website, stop affected processing and exercise your rights. Reading the policy itself never constitutes consent.
Read-aloud
For cloud read-aloud, we process question text, options, your selected voice and the account information needed for audio delivery in mainland China to provide reading audio.
Automatic reading is off by default and can be changed in Study settings. The app defaults to the device system voice and preserves a cloud voice you previously selected. If system speech is unavailable or fails to start before producing audio, it can fall back to the default female cloud voice. With a system voice, our product does not send reading text to our cloud speech service; device speech follows system settings and the applicable service rules. Cloud voice selection or fallback processes necessary information under the cloud read-aloud rules above. The Mini Program currently uses available cloud read-aloud capability.
Temporary reading text and audio are cleared after delivery. Completed or failed tasks without delivery confirmation enter cleanup after 15 minutes; queued tasks do so after 24 hours. Active generation or playback and error retries may delay cleanup. Necessary delivery records contain no reading text and remain for up to 24 hours. Remove local audio through Cache management or by clearing application data.
Academy, messages and support
Academy browsing processes catalog requests and necessary network information. Adding a book records the selected book, content version and copy operation to add it, prevent duplicate actions and synchronize it. Your answers, notes and favorites remain private. Free copying of Academy material does not remove the normal allowance rules for later AI tasks.
The message center displays announcements and news and records the account's reading position. When you send support text or select an image, we process the message, image, account identifier, time, read status and handling state to respond. Images are checked, resized and converted before storage in private storage, accessible to you and authorized support staff. We do not scan your whole photo library or automatically send support images to AI. Messages and images are retained as needed for the request, service continuity and disputes. Contact us for access or deletion; account deletion follows this policy.
WeChat Mini Program details
When you initiate login, linking or an operation requiring authentication, wx.login obtains a temporary code which is sent to our API. Our server uses its AppID and server-only AppSecret to verify the code with WeChat and receive the app-specific OpenID and, when provided, UnionID. The identity database keeps keyed digests for linking. Raw WeChat identifiers are not sent to AI. Business sessions use our own short-lived credentials; the session_key obtained for ordinary login is not returned to the client or stored as a business session credential. Phone login also verifies a mini-program code to establish a trusted client scope; it does not silently bind WeChat. An unlinked identity is guided to authenticate the existing phone account and explicitly confirm linking. We do not call getPhoneNumber to automatically obtain a WeChat-associated phone number.
Native apps and the Mini Program share the same account, API and database. Books, text questions, answer facts, notes, favorites, mistake annotations and entitlements are available across clients after synchronization is confirmed. Offline and background restrictions prevent a guarantee of instantaneous synchronization. Native app and Mini Program sandboxes cannot read one another, even on the same phone. Permission choices and appearance settings need not migrate. Unsynchronized facts must first be synchronized from their original client. Native app sessions and Mini Program sessions have separate exclusive-session groups; one session in each group can coexist.
Virtual payment runs only after applicable approval, production services and products are configured, the device supports it, and you confirm an order. Account/order identifiers, products, amount, currency, time, transaction state, platform transaction identifiers and necessary WeChat identity support verification, shared entitlement delivery, reconciliation and refund disputes. A fresh login code supplies payment verification; its session_key is used only for necessary signatures in server memory, never returned to the client or written to the order database. For later reconciliation, the order buyer's OpenID is encrypted using a separate AES-256-GCM key and bound to the original order. Unlinking or account closure does not immediately erase transaction context that must be retained for financial, audit, dispute or legal purposes. Retention is limited to these purposes and necessary applicable periods, followed by cleanup; it is not used for marketing. A client payment-window response does not itself grant entitlements; our server verifies the transaction. We do not collect bank-card numbers or payment passwords.
The current purchase page and WeChat capability determine availability. This notice does not assert that approval or live transactions have been enabled. Native-app payment parameters are not reused as Mini Program parameters. WeChat and payment operators process necessary platform information under their own terms and privacy rules.
Registration gifts and repeat-claim prevention
To determine eligibility for first-registration benefits and prevent repeated claims, we process the sign-in provider, a necessary identity digest and the eligibility registration time when an account is registered, a sign-in identity is linked or changed, or accounts are merged or closed. Free introductory question credits, initial free capabilities and reference-material trials follow the applicable eligibility rules. Paid benefits continue to be recorded under verified purchases and the applicable rules.
This eligibility record is stored separately from learning data. Unlinking, changing an identity, merging or closing an account does not restore eligibility already used. After account closure, we retain the eligibility record only to the extent necessary to prevent repeated claims by the same identity. We do not use it to restore the closed account's learning data, disclose a personal identity publicly or conduct marketing. Access and purposes are restricted. You may request access, correction, deletion or an explanation at support@jinlingai.tech; we verify and respond under the rights procedure in this policy.
Verified phone contacts and support verification
Information and purposes: in addition to the number digest and masked hint used for identity matching, we may retain the complete phone number you enter and verify by SMS, together with its verification time, for account services, human support contact you request, account recovery, necessary security verification, and necessary contact and tracing when investigating suspected violations of law or rules. We view it only when necessary. It is not provided to AI services, public libraries or ordinary users.
Trigger and choice: when registering, after you explicitly accept the current Privacy Policy containing this notice on the sign-in page and actively complete SMS verification, we may save the number verified in that registration when you complete registration agreement confirmation. In other cases, a complete number is saved only after you explicitly accept the current Privacy Policy and then actively complete SMS verification of that account's phone number. Before that acceptance, the original sign-in verification may complete, but no new complete-number record is saved. Reading the policy, an existing signed-in session, password sign-in or acceptance of an older version does not authorize this new storage. Historical digests and masked numbers cannot be reversed, and missing numbers are not inferred or reconstructed.
Storage and safeguards: the complete number is encrypted with AES-GCM in our own service database in mainland China and validated against its identity digest. Ordinary account APIs, user lists and ordinary business logs do not return or record it. A suitably authorized super administrator may briefly view it only when necessary for the stated purposes, after re-verifying their current password and entering a specific reason. The interface is masked by default and hides the revealed number after approximately 30 seconds. Access, staff identity, subject account, time and reason are audited without including the complete number. The display timeout protects the interface; it does not delete the stored number after 30 seconds.
Retention and cleanup: the complete number remains only while it is bound to a valid account, including an account suspended for suspected violations, and necessary for these services. Unlinking or changing the number clears the previous complete-number record; the new number must meet the consent and SMS-verification conditions above. During the account-closure cancellation period, new complete-number records are not saved and administrators cannot view them; completed closure clears them. On account merger, only a verified phone association actually retained and transferred to an active destination account may remain. Removed phone associations and records belonging to an ended source account are cleared according to those associations. Identity digests, registration eligibility, transaction records and security audits that must be retained follow the existing rules and are not used to restore cleared complete numbers. Backup restoration still applies corresponding deletion records.
No marketing consent: accepting this policy, linking a phone number or receiving support does not consent to marketing calls, promotional messages or contact-list export. This complete-number feature is limited to the stated account, support and security purposes. Other processing requires an appropriate legal basis, notice and any required consent.
Access, correction, deletion and withdrawal: manage linked numbers in Account management, or contact support@jinlingai.tech to request access, correction, deletion of the complete-number record or withdrawal from this processing. We handle requests through the identity-verification and rights procedures in this policy. Withdrawal does not invalidate processing based on earlier valid consent, and stopping complete-number storage does not automatically delete other records subject to legal retention.
Continuing withdrawal: after support verifies and carries out your request to stop retention, the account's saved complete number is cleared. Only the account-linked stop status and time remain, without the complete number. Later SMS verification, phone changes or account mergers do not automatically resume collection; mergers conservatively inherit the stop status. Digest-based sign-in, SMS verification and learning remain available. The current console provides no operation to resume retention. Any future re-enablement must obtain your separate valid authorization.
Personalized learning experience cards
When you request a pocket-book learning experience card, we select the necessary questions, answers, explanations, knowledge points, answer records, mistake reasons and notes from that book. An exam experience card uses only the question snapshots, knowledge points, answers, assessment results, score and duration from the single exam attempt you select. It does not combine other attempts for the same book, daily practice records or private notes. Necessary material and your confirmed preferences are sent to the Alibaba Cloud Bailian Qwen service in Beijing described above for analysis, summarization and writing. This feature does not search the web or read private notes from other books. AI-generated text should use existing records without presenting inferences as events that occurred.
Unfinished preferences and temporary dialogue are stored under your account so you can continue across devices. After 30 days without continuing the discussion, a background task releases the reservation. Resuming reserves one use from your then-available benefits without resetting the preferences or accumulated budget. If interrupted generation can continue, only necessary recovery material is kept, for up to 30 days. Completion, ending or deleting the round clears unnecessary raw dialogue and temporary material while retaining necessary task, allowance and cost audit records. Each card has one current body; saving an edit replaces it without an extra AI original or editing history. Generated cards remain after deletion of the source book or exam record and can be deleted separately. Regeneration is unavailable when the source is no longer available. Account closure follows the Privacy Policy.
Pocket-book cards require at least 50% mastery of that book; exam cards require the selected attempt to be completed and assessed. Both types are managed together and share one allowance: one use is reserved before preference confirmation and charged when formal generation consumes tokens, including a partial or failed round. It is released only when no formal-generation cost is confirmed. Uncertain costs await reconciliation without charging another use. Registration grants three uses, the permanent upgrade adds three once, and active membership provides eight per Beijing calendar month. See Benefits for the current balance. Later declines in mastery do not prevent reading saved cards. Editing, copying and exporting PDF or Word requires no AI call or generation use. Regeneration opens a new preference-confirmation conversation and deletes the old edition only after successful creation; consumed uses are not refunded. AI can make mistakes; check its summaries against the original material.
To avoid repeating the first-time Create pocket book guide across devices, we store whether that guide has been shown under your account. This flag contains no study text and is cleared with account closure.
Updated: October 26, 2026 Effective: October 26, 2026
This agreement is between you and 南昌锦灵网络科技有限公司. Read it before using the relevant services, especially the provisions on account security, AI content, charges, backups, service changes and disputes. The Privacy Policy, personal information list and notices accepted for specific features explain their corresponding rules.
1. Eligibility and choice
The product is for users aged 14 or above. Users aged 14–17 should use it with a guardian's knowledge and guidance and obtain permission where required. Children under 14 must not register or submit personal information. Offline examples and features that do not need an account remain available. Refusing optional permissions or processing does not prevent unrelated features.
2. Account security
Use available account methods, including phone verification. Password login is for existing accounts; verification codes may also support phone binding and password recovery. Use a number you are entitled to use, protect credentials and never share codes. We identify accounts through valid authentication. Update your binding when changing or giving up a number and contact us promptly about misuse.
Necessary limits apply to suspicious logins, repeated code requests and abuse. Binding conflicts, merging and closure explain their consequences and require confirmation. You can contact support to challenge restrictions. Do not sell, rent, share or bypass account security and quota controls.
3. Content and intellectual property
You can create private pocket books and manage questions, notes, favorites, study records, imports, exports and synchronization. You or the lawful rights holder retain existing rights. You grant only the non-exclusive permission necessary to store, synchronize, parse, generate, display, export and secure requested content.
Provide only material you are entitled to use. Do not submit unlawful, infringing, confidential or unauthorized personal information, or use the service to obtain or distribute pirated full texts. Private storage does not excuse unlawful use. There is no public community; creating a pocket book does not publish it to other users.
4. AI assistance and labels
AI generates or assesses learning content from your topics, materials and questions. Results may contain errors, omissions, bias or inappropriate output. Verify important conclusions and do not rely solely on AI for medical, legal, financial or other professional decisions. You can edit, delete, correct or report content.
Read and confirm the AI service notice before first use. Necessary task content is sent only for corresponding requests to disclosed providers. Refusal leaves manual questions and ordinary learning available. Do not submit sensitive personal information, state secrets or trade secrets.
AI content carries visible labels such as “AI-assisted”, with source information and applicable metadata retained in corresponding exports. Do not maliciously remove, alter, forge or conceal labels or present generated content as authentic authoritative information. Report concerns in the app or to support@jinlingai.tech.
5. Free features, benefits and charges
Free features and quotas are shown on the benefits page. Any purchase must first disclose benefits, duration, price and restrictions and is governed by the confirmed order and applicable terms. When purchasing is unavailable, no purchase charge is initiated. Automatic renewal is not currently offered. Promotional or manually granted benefits do not authorize recurring charges.
AI quotas settle under the applicable rules, not simply because a request was submitted. Delivered and undelivered portions of failed or cancelled tasks settle according to actual delivery rules. Contact support about quota, payment or service disputes; statutory consumer rights remain protected.
6. Offline use, sync and deletion
Downloaded content supports offline study; AI, login and cross-device synchronization need connectivity. Offline edits synchronize when conditions permit. Confirm synchronization and export important content before replacing a device, uninstalling or clearing application data. Unsynchronized data and local-only resources may not be recoverable.
You can delete content, export data or request closure. Closure has a cancellable seven-day cooling-off period, followed by deletion or anonymization under the Privacy Policy. Legally retained information is limited to the required purpose and period.
Once you confirm an account-closure request, all existing login sessions are invalidated and the client signs out. During the seven-day cancellation period, you may verify your identity again, but the restricted session can only view closure status, cancel closure or sign out. It cannot read learning data, export content or perform other business operations. Cancelling closure restores normal use. After the period ends, associated data is deleted or anonymized under the Privacy Policy; legally retained information remains limited to the required purpose and period.
7. Responsible use and service quality
Do not attack, abuse, damage or bypass the service or infringe others' rights. Evidence-based risk controls should be proportionate, with a support channel for appeals. Maintenance, network or provider failures may interrupt service; we take reasonable recovery measures and explain material impacts where necessary.
We remain responsible for applicable security, privacy and consumer obligations. We do not exclude liability for intentional misconduct, gross negligence or other liability that cannot lawfully be excluded. Material changes or service termination will be notified and unfinished matters and data reasonably handled as required by law.
8. Changes, contact and disputes
Material changes are notified through appropriate prompts. Silence or continued use does not replace consent where renewed consent is required. You may stop affected services and manage your data and account. PRC law applies. Disputes may be negotiated or brought to a court with lawful jurisdiction; statutory complaint and remedy rights remain available.
You can preview available Academy books, add them to your library for free, and practice, take notes and review. Your copy is independent; later catalog changes do not automatically overwrite your edits. Later AI tasks still follow the applicable benefits and allowance rules. Academy material supports interest-based study and self-assessment; it is not certification by an examination body, publisher or professional institution and does not guarantee exam results. Respect content rights and source labels when sharing or exporting.
Announcements and news appear in the message center. Contact in-app support or support@jinlingai.tech for help. If your account is restricted or banned, you can still email us to request a review. Include your account identifier and issue, not passwords or verification codes.
Updated: October 27, 2026 Effective: October 27, 2026
Provided by 南昌锦灵网络科技有限公司; read together with the Privacy Policy and third-party list. Contact: support@jinlingai.tech. The categories below explain data, purposes, triggers and storage.
1. Basic networking and security
Data: IP address, request time, app version, platform, language, necessary request identifiers and security state. Trigger/purpose: network features after your initial privacy choice, for configuration, connections, troubleshooting and abuse prevention. Website access generates necessary requests. Storage: necessary server logs and security records, subject to legal and purpose-limited retention.
2. Authentication and account management
Data: entered phone number, password/code, number digest/masked hint, user ID, app-instance/session information, age declaration, agreement versions and security events. Trigger/purpose: requested login, binding, reset, session management or closure, for authentication and security. Storage/recipients: our identity database and secure storage; passwords use salted one-way derived values. When SMS is available and requested, Tencent Cloud and carriers process the number, verification message and delivery status. Codes last five minutes. No plaintext passwords are stored and ordinary logs omit codes.
WeChat authentication and initial profile (supported Android versions): only after you explicitly request WeChat login, binding or security verification and authorize it in WeChat does our server process a one-time code, random verification state, OpenID and UnionID when available to verify identity and associate accounts using a digest. Under that authorization, our server may also retrieve your nickname and avatar URL from WeChat. Available nickname and avatar data is adopted as the initial profile only when that authorization creates a new account. Login, binding or security verification for an existing account does not overwrite its nickname or avatar. Avatars are fetched only from trusted official WeChat image addresses, validated and processed, then copied to our private avatar storage. If optional profile data is absent or unavailable, default profile values are used without blocking successful identity verification. You can later edit your profile. We do not send phone numbers or learning content to WeChat. Codes and WeChat access tokens are not written to ordinary logs or persistent mobile storage. You can revoke authorization in WeChat settings, use phone login or manage the association in our account-security settings.
QQ authentication (supported Android versions): the QQ Connect SDK initializes and checks QQ/TIM installation only after you read the relevant privacy notice and explicitly choose QQ login, binding or security verification. It handles the access token, expiry, OpenID and local correlation state following your authorization in QQ. Our server verifies the token and its application with QQ and associates an identity digest with your account. Available QQ nickname/avatar may initialize a newly registered profile; an existing profile is not overwritten. You may edit your profile, use phone login or manage account associations. Cancellation does not complete login. Tokens are used for verification and are not written to our ordinary logs or persistent account storage. We do not send your phone number, questions, answers or library to QQ. The provider is Shenzhen Tencent Computer Systems Company Limited. Device model supports SDK compatibility and diagnostics; networking involves IP and network status. See the third-party list for details and revocation options.
3. Nickname and avatar
Data: your chosen nickname and selected/cropped avatar, or the nickname, avatar URL and image adopted during authorized WeChat registration as described above, plus resource identifiers and necessary metadata. Trigger/purpose: display after you confirm a profile edit, or initial profile values when you authorize WeChat and create a new account. Later login, binding or security verification for existing accounts does not overwrite their profiles. Missing or unavailable optional data uses defaults; cancelling a manually selected photo does not upload it. Storage: nicknames and necessary avatar URLs are stored in our database; validated and processed avatar images are copied to private COS and associated through resource identifiers, with account-isolated display caches. You can edit your profile; the whole photo library is not read.
4. Creating, studying and synchronizing
Data: books, questions, answers, notes, favorites, plans, attempts, times, progress and review state. Trigger/purpose: creation, editing, importing, study and synchronization for offline use, statistics and multi-device continuity. Storage: local SQLite and our database; deletion and closure follow the recovery windows, cleanup and lawful-retention rules in the policy.
5. AI and selected uploads
Data: requested topics, book/author details, instructions, selected files/URLs, file name/type/size/digest, extracted text, necessary images, scanned pages and diagrams from the selected material, and necessary questions/answers/context. Trigger/purpose: after confirmation of the AI notice, adding reference material can start text recognition, image and diagram interpretation, and organization before Generate is pressed. You may also request generation, follow-up questions, lookups or grading. A changed notice requires confirmation before the next relevant AI use. Storage/recipients: private COS and our task processing store originals and extraction results; necessary text and converted/resized reference images go to Beijing Model Studio Qwen. Uploaded originals and extraction results not used in a task become eligible for cleanup after 24 hours. Task material enters asynchronous cleanup after completion, cancellation or final failure. AI interpretation results produced during preparation become eligible for periodic cleanup 24 hours after completion. Necessary duplicate-request digests, billing and security audit records are retained for their respective purposes; cleanup errors are retried. Model Studio handles call records under applicable terms and legal duties, without a promise of zero retention. Ordinary study does not need these features, and other device files are not scanned.
6. Optional speech, reminders and overlay
Speech input for explanations, answers or question notes starts at your request. Sign in, confirm the speech-to-text notice and allow microphone access; the Mini Program also requests the privacy authorization required by WeChat. A recording lasts up to three minutes. Our server forwards that recording to Qwen-ASR in Alibaba Cloud Model Studio's Beijing region, operated by Alibaba Cloud Computing Co., Ltd. and the applicable Model Studio operator. It does not attach question answers, your phone number or your entire library.
In Teach the AI, recording is transcribed in the background. Before submission, the text stays in the current account's local explanation draft for recovery and submission. It is not shown on the explanation, feedback or history screens and cannot be edited. Typed input has a separate draft; switching input methods does not merge them. Ordinary short-answer questions and question notes show the transcription for you to review and edit. Explanations and answers are assessed only after you submit them. Voice notes record your study thoughts; only text you choose to save becomes a question note and syncs under the existing rules. Voice notes are not graded. Finishing a recording or transcription does not submit an answer or save a question note. The Mini Program study page may keep an unsaved note draft on this device so you can return to edit it; this draft does not sync as a saved note.
The app clears temporary recordings after successful transcription, cancellation or leaving the page. Failed recordings remain only on that page for up to five minutes for retry. The Mini Program deletes the recording file after reading it. Failed audio remains only in that page's memory for up to five minutes for retry and is cleared after successful transcription, cancellation, leaving the page or changing accounts. Recordings are not included in learning-data synchronization. Our server forwards audio during request processing without writing it to databases, object storage or business logs. Encrypted transcripts are cached for up to five minutes; duplicate-request digests and necessary security state last up to 24 hours. Explanations and answers you submit, and note text you choose to save, are retained under the rules for those learning records and notes. Alibaba Cloud handles necessary call records under its service terms and legal obligations. You can use typed input instead. Cancellation cannot recall data already sent.
Reminders, permission preferences and overlay state remain on-device; they do not observe other apps.
7. Feedback, reports and rights requests
Data: submitted description/category, chosen attachments, optional contact, necessary account/verification information and handling state. Trigger/purpose: your request, for troubleshooting, responses, content safety and rights protection. Storage: our service and access-controlled administration, for limited handling/dispute/legal retention. Do not submit unrelated sensitive data.
8. Optional usage statistics
Data: limited feature events and consent state, not original questions or complete study content. Trigger/purpose: off by default; your opt-in and enabled server configuration allow product improvement statistics. Storage: purpose-limited processing by our service. Disabling it does not affect core features.
9. Purchases, orders and benefits
Data: order and product identifiers, amount, currency, in-app account association identifier, transaction identifiers, and payment, refund and benefit status. Trigger/purpose: after you explicitly confirm a product in a supported domestic Android channel, payment is completed through Hupijiao WeChat checkout. Our service verifies the result before updating benefits and supports order queries and after-sales requests. Current Android memberships renew manually without automatic debits. On iOS, necessary product, account association and Apple-signed transaction information is processed only when App Store purchases, products and production configuration are available and you explicitly confirm a purchase. Restoration verifies existing transactions without charging again; unavailable or unconfigured channels do not initiate real transactions. Storage/recipients: our database stores records needed to complete transactions, verify benefits and lawfully handle after-sales requests. Payment channels receive necessary transaction fields; see the third-party list for recipients. We do not send questions, answers, notes or phone numbers to payment providers. Our product does not read bank-card numbers, payment passwords or payment-platform login credentials. Checkout and payment platforms handle information you submit on their pages under their own rules.
We do not obtain contacts, location, SMS content, call logs, advertising identifiers or all device files. See the Privacy Policy for retention, access/copy, correction/deletion, withdrawal and closure.
Read-aloud
For cloud read-aloud, we process question text, options, your selected voice and the account information needed for audio delivery in mainland China to provide reading audio. See the Privacy Policy for retention periods and your choices.
Academy, announcements and support messages
Academy: selected books, content versions and copy records, used to add content to your library and synchronize it. Personal practice records are not published. Announcements and news: the account identifier and reading position, used to show unread items. Support messages: text and images you choose to send, account identifier, time and handling state, used to respond. Images are checked and converted before storage in private object storage and are not automatically sent to AI. Access is limited to you and authorized staff. Messages and images are retained as needed for the request, service continuity and disputes; contact support for access or deletion.
WeChat Mini Program details
Data: requested authentication codes, AppID, OpenID and conditional UnionID returned by WeChat, keyed identity digests and binding state; for purchases, account, product/order identifiers, amount, currency, time, platform transaction identifiers, state and necessary signatures. Purpose/trigger: production configuration permits verification of client scope, login and explicit linking. Payment approval and an order you confirm permit verification, shared entitlement accounting, reconciliation, refund disputes and abuse prevention. Phone numbers are entered manually, without getPhoneNumber. Storage/recipients: WeChat and the applicable contractual operators, plus our identity/business/transaction services. Identity linking uses keyed digests. The order buyer OpenID is encrypted with a separate key and bound to its order for reconciliation. Payment session_key is transient in server memory for necessary signatures, not returned to clients or written to order storage. Required financial, audit and dispute records remain purpose-limited after unlinking/closure. Native apps and Mini Programs cannot read each other's sandboxes; authorized APIs synchronize core learning data, while ancillary local images do not automatically migrate.
Registration-gift eligibility records
Information: the sign-in provider, a necessary identity digest and the eligibility registration time. Purpose and trigger: registration, linking or changing a sign-in identity, account merger or closure triggers checks of first-registration eligibility to prevent repeated free question credits, initial free capabilities or reference-material trials. Paid benefits are separately recorded under verified purchases and the applicable rules. Storage: an eligibility record in our own database, separate from learning data. Unlinking, changing an identity, merging or closing an account does not restore eligibility already used. After closure, the record remains only to the extent necessary to prevent repeat claims; it is not used to restore closed learning data, disclose a personal identity publicly or conduct marketing. Requests for access, correction, deletion or explanation follow the Privacy Policy.
Verified phone contacts and support verification
Information and purposes: in addition to the number digest and masked hint used for identity matching, we may retain the complete phone number you enter and verify by SMS, together with its verification time, for account services, human support contact you request, account recovery, necessary security verification, and necessary contact and tracing when investigating suspected violations of law or rules. We view it only when necessary. It is not provided to AI services, public libraries or ordinary users.
Trigger and choice: when registering, after you explicitly accept the current Privacy Policy containing this notice on the sign-in page and actively complete SMS verification, we may save the number verified in that registration when you complete registration agreement confirmation. In other cases, a complete number is saved only after you explicitly accept the current Privacy Policy and then actively complete SMS verification of that account's phone number. Before that acceptance, the original sign-in verification may complete, but no new complete-number record is saved. Reading the policy, an existing signed-in session, password sign-in or acceptance of an older version does not authorize this new storage. Historical digests and masked numbers cannot be reversed, and missing numbers are not inferred or reconstructed.
Storage and safeguards: the complete number is encrypted with AES-GCM in our own service database in mainland China and validated against its identity digest. Ordinary account APIs, user lists and ordinary business logs do not return or record it. A suitably authorized super administrator may briefly view it only when necessary for the stated purposes, after re-verifying their current password and entering a specific reason. The interface is masked by default and hides the revealed number after approximately 30 seconds. Access, staff identity, subject account, time and reason are audited without including the complete number. The display timeout protects the interface; it does not delete the stored number after 30 seconds.
Retention and cleanup: the complete number remains only while it is bound to a valid account, including an account suspended for suspected violations, and necessary for these services. Unlinking or changing the number clears the previous complete-number record; the new number must meet the consent and SMS-verification conditions above. During the account-closure cancellation period, new complete-number records are not saved and administrators cannot view them; completed closure clears them. On account merger, only a verified phone association actually retained and transferred to an active destination account may remain. Removed phone associations and records belonging to an ended source account are cleared according to those associations. Identity digests, registration eligibility, transaction records and security audits that must be retained follow the existing rules and are not used to restore cleared complete numbers. Backup restoration still applies corresponding deletion records.
No marketing consent: accepting this policy, linking a phone number or receiving support does not consent to marketing calls, promotional messages or contact-list export. This complete-number feature is limited to the stated account, support and security purposes. Other processing requires an appropriate legal basis, notice and any required consent.
Access, correction, deletion and withdrawal: manage linked numbers in Account management, or contact support@jinlingai.tech to request access, correction, deletion of the complete-number record or withdrawal from this processing. We handle requests through the identity-verification and rights procedures in this policy. Withdrawal does not invalidate processing based on earlier valid consent, and stopping complete-number storage does not automatically delete other records subject to legal retention.
Continuing withdrawal: after support verifies and carries out your request to stop retention, the account's saved complete number is cleared. Only the account-linked stop status and time remain, without the complete number. Later SMS verification, phone changes or account mergers do not automatically resume collection; mergers conservatively inherit the stop status. Digest-based sign-in, SMS verification and learning remain available. The current console provides no operation to resume retention. Any future re-enablement must obtain your separate valid authorization.
Personalized learning experience cards
When you request a pocket-book learning experience card, we select the necessary questions, answers, explanations, knowledge points, answer records, mistake reasons and notes from that book. An exam experience card uses only the question snapshots, knowledge points, answers, assessment results, score and duration from the single exam attempt you select. It does not combine other attempts for the same book, daily practice records or private notes. Necessary material and your confirmed preferences are sent to the Alibaba Cloud Bailian Qwen service in Beijing described above for analysis, summarization and writing. This feature does not search the web or read private notes from other books. AI-generated text should use existing records without presenting inferences as events that occurred.
Unfinished preferences and temporary dialogue are stored under your account so you can continue across devices. After 30 days without continuing the discussion, a background task releases the reservation. Resuming reserves one use from your then-available benefits without resetting the preferences or accumulated budget. If interrupted generation can continue, only necessary recovery material is kept, for up to 30 days. Completion, ending or deleting the round clears unnecessary raw dialogue and temporary material while retaining necessary task, allowance and cost audit records. Each card has one current body; saving an edit replaces it without an extra AI original or editing history. Generated cards remain after deletion of the source book or exam record and can be deleted separately. Regeneration is unavailable when the source is no longer available. Account closure follows the Privacy Policy.

4. Local components
Flutter renders the interface; Drift/SQLite stores account-isolated offline data; flutter_secure_storage uses secure system storage for credentials; shared_preferences stores local preferences; http transports requests; package_info_plus reads app version; path_provider locates private app directories; url_launcher opens the system browser or mail app only when you select a link. These components do not send learning data to their authors on our behalf.
file_selector and image_picker use system pickers for selected material/avatars only. They do not read the entire library, contacts or call logs. flutter_local_notifications, flutter_timezone and timezone support reminders and time-zone scheduling you enable, not remote push.
Sources: https://flutter.dev/ and https://pub.dev/ . Component versions may change through maintenance; material changes to processing purposes or scope require new notice.
5. Voice input and Android study overlay
Speech input for explanations, answers or question notes starts at your request. Sign in, confirm the speech-to-text notice and allow microphone access; the Mini Program also requests the privacy authorization required by WeChat. A recording lasts up to three minutes. Our server forwards that recording to Qwen-ASR in Alibaba Cloud Model Studio's Beijing region, operated by Alibaba Cloud Computing Co., Ltd. and the applicable Model Studio operator. It does not attach question answers, your phone number or your entire library.
In Teach the AI, recording is transcribed in the background. Before submission, the text stays in the current account's local explanation draft for recovery and submission. It is not shown on the explanation, feedback or history screens and cannot be edited. Typed input has a separate draft; switching input methods does not merge them. Ordinary short-answer questions and question notes show the transcription for you to review and edit. Explanations and answers are assessed only after you submit them. Voice notes record your study thoughts; only text you choose to save becomes a question note and syncs under the existing rules. Voice notes are not graded. Finishing a recording or transcription does not submit an answer or save a question note. The Mini Program study page may keep an unsaved note draft on this device so you can return to edit it; this draft does not sync as a saved note.

The Mini Program deletes the recording file after reading it. Failed audio remains only in that page's memory for up to five minutes for retry and is cleared after successful transcription, cancellation, leaving the page or changing accounts. Recordings are not included in learning-data synchronization. Our server forwards audio during request processing without writing it to databases, object storage or business logs. Encrypted transcripts are cached for up to five minutes; duplicate-request digests and necessary security state last up to 24 hours. Explanations and answers you submit, and note text you choose to save, are retained under the rules for those learning records and notes. Alibaba Cloud handles necessary call records under its service terms and legal obligations. You can use typed input instead. Cancellation cannot recall data already sent.
Domestic Android overlays use system overlay and visible foreground-service capabilities you enable and can exit/revoke. They do not observe other apps through accessibility or screen recording. Google Play and iOS builds do not offer this overlay.
6. WeChat Open SDK (Android WeChat authentication)
Provider: 深圳市腾讯计算机系统有限公司 (Shenzhen Tencent Computer Systems Company Limited). Method: WeChat Open SDK 6.8.40 in the Android app and WeChat credential verification and authorized profile retrieval from our server, including avatar-image retrieval within the scope described below. Purpose/data: login, binding or account-security verification that you request. The SDK checks whether WeChat is installed and sends this app's identifier, authorization scope and a random verification state to WeChat. After you authorize in WeChat, our app sends the one-time code and verification state to our server. Our server verifies the code with WeChat, receives OpenID and UnionID when available, and associates your account using a digest. Under that authorization, our server may also retrieve your nickname and avatar URL from WeChat, adopting them as initial profile values only when that authorization creates a new account. Login, binding or security verification for existing accounts does not overwrite their profiles. Avatars are fetched only from trusted official WeChat image addresses, validated and processed, then copied to our private avatar storage. Missing or unavailable optional profile data uses default profile values without blocking successful identity verification; users can edit their profiles later. We do not send phone numbers, questions, answers or your library to WeChat. Authorization codes and WeChat access tokens are not written to ordinary logs or persistent mobile storage. Trigger: only after your privacy choice and explicit WeChat login, binding or verification action does the SDK initialize, check installation and request authorization. Opening the app, ordinary study and phone login do not initialize it. Missing WeChat prompts installation; cancelled authorization does not create a login session. Location/choices: WeChat processes relevant information in China under its rules. You can use phone login, manage the association in account security (keep another usable login method before unlinking), or revoke authorization in WeChat's personal-information and permissions settings. Users aged 14–17 should obtain written guardian consent before using WeChat SDK features. Policy: https://support.weixin.qq.com/cgi-bin/mmsupportacctnodeweb-bin/pages/RYiYJkLOrQwu0nb8 Development guide: https://developers.weixin.qq.com/doc/oplatform/Mobile_App/WeChat_Login/Development_Guide.html
7. QQ Connect SDK (Android QQ authentication)
Provider: Shenzhen Tencent Computer Systems Company Limited. Method: QQ Connect SDK 3.5.19 on Android; QQ identity and profile APIs on our server. Purpose/data: QQ authentication (supported Android versions): the QQ Connect SDK initializes and checks QQ/TIM installation only after you read the relevant privacy notice and explicitly choose QQ login, binding or security verification. It handles the access token, expiry, OpenID and local correlation state following your authorization in QQ. Our server verifies the token and its application with QQ and associates an identity digest with your account. Available QQ nickname/avatar may initialize a newly registered profile; an existing profile is not overwritten. You may edit your profile, use phone login or manage account associations. Cancellation does not complete login. Tokens are used for verification and are not written to our ordinary logs or persistent account storage. We do not send your phone number, questions, answers or library to QQ. The provider is Shenzhen Tencent Computer Systems Company Limited. Device model supports SDK compatibility and diagnostics; networking involves IP and network status. See the third-party list for details and revocation options. Trigger: explicit use of QQ authorization only; app launch, ordinary study and phone login do not initialize the SDK. Installation checks are limited to QQ/TIM, not a full app inventory. This release does not use QQ sharing, friend, photo or clipboard features. Location/choices: processing in China under QQ Connect rules. Revoke authorization through QQ authorization management or unlink in our account security settings, retaining another usable login method. Users aged 14–17 should obtain guardian consent. Privacy rules: https://wiki.connect.qq.com/qq互联sdk隐私保护声明
8. Payment services and feature availability
Hupijiao WeChat checkout (domestic Android channels) Providers: the Hupijiao (Xunhu) payment interface is provided by 重庆直数电子科技有限公司; WeChat Pay is provided by 财付通支付科技有限公司. Method: our server calls the Hupijiao interface. Your explicit payment action opens its checkout in a browser, where you follow the prompts to pay with WeChat. Our app does not embed a Hupijiao data-collection SDK. Purpose/data: order and product identifiers, amount, currency, in-app account association identifier, transaction identifiers, and payment or refund status support payment, order verification, benefit delivery, reconciliation and after-sales support. Requests also contain the merchant application identifier, notification address, signature and replay-protection fields. We do not send phone numbers, questions, answers or notes to the payment channel. Payment platforms handle information provided on their pages and necessary network/security data under their own rules; our product does not read bank-card numbers, payment passwords or payment-platform login credentials. Trigger: you select a product and explicitly confirm payment. Browsing, studying or simply opening the app does not create a payment transaction. Current Android memberships renew manually without automatic debits. Hupijiao service agreement, including provider and data-processing information: https://admin.xunhupay.com/xieyi.html WeChat Pay privacy policy: https://www.tenpay.com/v3/helpcenter/low/privacy.shtml
iOS App Store (subject to availability on that platform) Provider: Apple and the applicable service entities identified in its privacy policy. Method: Apple system StoreKit and server-side transaction verification. Product identifiers, in-app account association identifiers, Apple-signed transactions, transaction identifiers and status are processed for verification, benefit updates and restoration only when purchases, products and production configuration are available and you explicitly confirm a purchase. We do not provide Apple with questions, answers or notes. Restoration verifies existing transactions without charging again. Our product does not read bank-card numbers, payment passwords or Apple login credentials. Unavailable or unconfigured channels do not initiate real transactions; listing this capability does not mean sales are currently available. Purchase type, price, duration and any automatic renewal depend on terms clearly shown and confirmed by you on the purchase page and Apple confirmation sheet when the feature is available. Apple App Store privacy notice: https://www.apple.com/legal/privacy/data/en/app-store/
Apple social login and WeChat or QQ login on iOS are not enabled, and no authorization requests are made for those unavailable login scenarios. There are no advertising, attribution or third-party behavioral analytics SDKs. Before adding recipients, enabling these services or materially changing purposes, we update this list and provide required notice/consent. Contact us for explanations or rights assistance.
WeChat Mini Program details
Provider: 深圳市腾讯计算机系统有限公司 and the applicable operator identified in the WeChat/virtual-payment agreements at activation. Method: native WeChat host, wx.login, our backend jscode2session and Mini Program virtual-payment APIs; this is not a Mini Program SDK embedded in the Flutter app. Data/purpose: temporary code, AppID, OpenID and conditional UnionID verify login and account linking you confirm. Phone numbers are entered manually and verified by SMS; getPhoneNumber is not used. Necessary product/order information, amount, currency, signatures and platform identifiers support transactions and reconciliation. Raw identifiers are not sent to AI. Identity records contain keyed digests; order-buyer OpenID is separately encrypted. The payment session_key is transient in server memory and never returned to clients. Trigger: your requested login, binding or confirmed purchase, with real configuration and platform availability. No local simulation replaces formal authentication. Bindings and sessions can be managed in account settings; required transaction records remain subject to the Privacy Policy. Privacy: https://weixin.qq.com/cgi-bin/readtemplate?lang=zh_CN&t=weixin_agreement&s=privacy Platform privacy: https://developers.weixin.qq.com/miniprogram/dev/framework/user-privacy/PrivacyAuthorize.html Login: https://developers.weixin.qq.com/miniprogram/dev/framework/open-ability/login.html Virtual payment: https://developers.weixin.qq.com/miniprogram/dev/api/payment/wx.requestVirtualPayment.html
The Mini Program uses native UI, account-isolated WeChat private storage and a pending synchronization queue, not Flutter/SQLite or native-app secure-storage plugins. File/media/avatar pickers run only when you select materials or an avatar, using the WeChat privacy flow where required. Downloaded avatars and support images are for display. Exported study files are shared only with a recipient you select. The Mini Program offers optional speech-to-text through its native recorder as disclosed above, but not local reminders, overlays or optional behavioral analytics SDKs. WeChat's own device/network processing is governed by its privacy policy.
Updated: October 26, 2026 Effective: October 26, 2026
Read and confirm before initiating AI use. Refusal leaves offline examples, manual questions and ordinary learning available. Operator: 南昌锦灵网络科技有限公司. Contact: support@jinlingai.tech.
1. Material interpretation, text, search, reasoning, review and grading
Our backend calls Qwen3.7-Flash through Alibaba Cloud Model Studio in Beijing to recognize text, interpret images and diagrams, and organize selected reference material, as well as for question generation/review, explanations, follow-up questions, resource lookup, teaching preparation/assessment and open-answer grading. The provider is 阿里云计算有限公司 and the applicable Model Studio operator.
Your requested action determines necessary topics, book/author details, goals, instructions, selected-file/URL extracted text, related questions/options/answers, grading conditions, submitted transcription text and limited context. Adding files first uploads them to our private storage; added links initially stay on the current client. Reading, parsing and AI interpretation begin after you select Generate. Necessary images, scanned pages and diagrams are converted and resized, then sent with relevant text to that service for interpretation and organization. Confirm this notice before first use and again before the next relevant AI use after it changes. Model Studio's built-in search processes necessary queries when public lookup is needed; not every request uses search. Generic motivational messages do not require your study text.
We do not automatically send phone numbers, passwords, codes, session tokens or your entire library. Cancellation cannot recall already-sent data. Historical content retains its original source records rather than attributing it falsely to a new model.
Bundled pocket-book covers are static app resources.
2. Speech and submission control
Speech input for explanations, answers or question notes starts at your request. Sign in, confirm the speech-to-text notice and allow microphone access; the Mini Program also requests the privacy authorization required by WeChat. A recording lasts up to three minutes. Our server forwards that recording to Qwen-ASR in Alibaba Cloud Model Studio's Beijing region, operated by Alibaba Cloud Computing Co., Ltd. and the applicable Model Studio operator. It does not attach question answers, your phone number or your entire library.
In Teach the AI, recording is transcribed in the background. Before submission, the text stays in the current account's local explanation draft for recovery and submission. It is not shown on the explanation, feedback or history screens and cannot be edited. Typed input has a separate draft; switching input methods does not merge them. Ordinary short-answer questions and question notes show the transcription for you to review and edit. Explanations and answers are assessed only after you submit them. Voice notes record your study thoughts; only text you choose to save becomes a question note and syncs under the existing rules. Voice notes are not graded. Finishing a recording or transcription does not submit an answer or save a question note. The Mini Program study page may keep an unsaved note draft on this device so you can return to edit it; this draft does not sync as a saved note.
The app clears temporary recordings after successful transcription, cancellation or leaving the page. Failed recordings remain only on that page for up to five minutes for retry. The Mini Program deletes the recording file after reading it. Failed audio remains only in that page's memory for up to five minutes for retry and is cleared after successful transcription, cancellation, leaving the page or changing accounts. Recordings are not included in learning-data synchronization. Our server forwards audio during request processing without writing it to databases, object storage or business logs. Encrypted transcripts are cached for up to five minutes; duplicate-request digests and necessary security state last up to 24 hours. Explanations and answers you submit, and note text you choose to save, are retained under the rules for those learning records and notes. Alibaba Cloud handles necessary call records under its service terms and legal obligations. You can use typed input instead. Cancellation cannot recall data already sent.
Our service and COS are in mainland China; Model Studio text calls and reference-image interpretation use Beijing. Uploaded originals and extraction results not used in a generation task become eligible for cleanup after 24 hours. Task originals, extraction results and intermediates enter asynchronous cleanup after completion, cancellation or final failure; errors are retried. AI interpretation results cached during material preparation to avoid repeat processing become eligible for periodic cleanup 24 hours after completion. Material summaries associated with a generation task are cleared when that task ends. Necessary duplicate-request digests, billing and security audit records are retained for their respective purposes. Model Studio processes requests and call records under its applicable terms, privacy rules and legal duties. We do not promise zero retention by every recipient. Submit only ordinary study material you may lawfully provide, not sensitive personal information, state/trade secrets or unauthorized information about others.
AI output may contain errors, omissions or inappropriate content. Structure/safety checks do not guarantee accuracy. Verify important conclusions and do not replace professional advice with AI. Generated content carries visible AI-assistance labels; corresponding exports retain source labels and applicable metadata. Do not maliciously remove, alter, forge or conceal labels.
Edit, delete, correct or report content, or email support@jinlingai.tech for explanations, privacy requests or assistance contacting a provider. Material changes to recipients, purposes or data scope will be disclosed with necessary consent before implementation.
Personalized learning experience cards
When you request a pocket-book learning experience card, we select the necessary questions, answers, explanations, knowledge points, answer records, mistake reasons and notes from that book. An exam experience card uses only the question snapshots, knowledge points, answers, assessment results, score and duration from the single exam attempt you select. It does not combine other attempts for the same book, daily practice records or private notes. Necessary material and your confirmed preferences are sent to the Alibaba Cloud Bailian Qwen service in Beijing described above for analysis, summarization and writing. This feature does not search the web or read private notes from other books. AI-generated text should use existing records without presenting inferences as events that occurred.
Unfinished preferences and temporary dialogue are stored under your account so you can continue across devices. After 30 days without continuing the discussion, a background task releases the reservation. Resuming reserves one use from your then-available benefits without resetting the preferences or accumulated budget. If interrupted generation can continue, only necessary recovery material is kept, for up to 30 days. Completion, ending or deleting the round clears unnecessary raw dialogue and temporary material while retaining necessary task, allowance and cost audit records. Each card has one current body; saving an edit replaces it without an extra AI original or editing history. Generated cards remain after deletion of the source book or exam record and can be deleted separately. Regeneration is unavailable when the source is no longer available. Account closure follows the Privacy Policy.
Pocket-book cards require at least 50% mastery of that book; exam cards require the selected attempt to be completed and assessed. Both types are managed together and share one allowance: one use is reserved before preference confirmation and charged when formal generation consumes tokens, including a partial or failed round. It is released only when no formal-generation cost is confirmed. Uncertain costs await reconciliation without charging another use. Registration grants three uses, the permanent upgrade adds three once, and active membership provides eight per Beijing calendar month. See Benefits for the current balance. Later declines in mastery do not prevent reading saved cards. Editing, copying and exporting PDF or Word requires no AI call or generation use. Regeneration opens a new preference-confirmation conversation and deletes the old edition only after successful creation; consumed uses are not refunded. AI can make mistakes; check its summaries against the original material.

AI Pocket Book Membership and Paid Benefits Agreement
Updated: 3 October 2026 Effective: 3 October 2026
This agreement covers membership and other paid benefits available in AI Pocket Book, operated by Nanchang Jinling Network Technology Co., Ltd. Contact: support@jinlingai.tech.
Before purchase
The purchase page shows the product, price, term, included features or AI allowances and applicable scope. Monthly and annual memberships have a defined term. A one-time upgrade is not membership and does not make all AI use permanently free. Choose according to the product description; benefits follow the order you confirm.
Current memberships renew manually without automatic charges. Domestic Android uses the displayed WeChat checkout. iOS and the Mini Program offer their platform purchase methods only when the feature and configured products are available. Unavailable channels do not initiate transactions. Restoring purchases checks existing transactions without charging again.
Delivery, use and support
We verify payment before delivering benefits. Closing checkout, a client payment-complete message or a timeout does not replace order verification. Check membership dates, allowances and orders on the benefits page. If delivery is delayed, check the order before paying again.
AI tasks settle according to the applicable rules and actual delivery, including failure, cancellation or partial completion. Contact in-app support or email with your order details about charges, benefits or refunds; do not send payment passwords or verification codes. Refunds, unused benefits and disputes are handled under applicable law. This agreement does not exclude statutory consumer rights.
The User Agreement and Privacy Policy apply to other matters.
Current memberships renew manually. There is no automatic renewal or charge after expiry. To renew, select a product in the app and confirm payment again.
Check the price, term and included benefits before paying. We do not obtain automatic-debit authorization for bank cards, WeChat or Alipay, and do not read payment passwords. For an order or benefits issue, contact in-app support or support@jinlingai.tech.
If automatic renewal is offered later, its price, charging schedule and cancellation method will be explained before activation and require your explicit choice. This notice does not authorize automatic charges.
