Release date: August 4, 2026 Effective date: August 5, 2026 Record version: privacy-2026-08-v6

Key Points

  • There is no need to register an account for the basic prompt function. Documents, hotwords, settings and reading positions are saved locally on your device by default.
  • AI Follow uses a local speech model, and microphone audio, recognition, and text alignment will not be automatically uploaded due to normal use.
  • When launching for the first time, only after you explicitly click "Agree and Continue" will the app initialize networking capabilities such as account, membership, device installation identification, diagnostic identity, and update check.
  • You can choose "Disagree, use local functions only"; local documents, editing, basic Auto Scroll and local settings can still be used, and the app will not repeatedly pop up consent requests.
  • The app does not download, verify, or install the APK. The official website package only forwards the official download page to the default browser; the Xiaomi and Tencent MyApp channel packages only redirect to the corresponding store or the corresponding store webpage.
  • The selected content will not leave the device until you actively generate the diagnostic package and select the recipient in the system sharing panel.
  • Accounts, memberships and Alipay payments are optional online services. The corresponding information will only be processed when you actively log in, purchase, redeem or manage your account; it does not affect the basic prompt function that does not require login.

"Personal information" in this policy refers to various information related to an identified or identifiable natural person that is recorded electronically or by other means, excluding anonymized information. For content in the device that is only controlled by you and cannot be accessed by us, we will still explain how to handle it in this policy to help you understand product behavior.

2. How we process information

We follow the principles of legality, legitimacy, necessity and good faith and only process information needed to implement functions for clear and reasonable purposes. The basic teleprompter service does not require registering an account or providing unnecessary personal information.

Startup and version safety App version number, release channel, as well as IP address, request time, response status and basic information about device network requests usually generated by the server Only after you agree to the current privacy policy, each app process will be cold-started to check for normal updates, mandatory security updates, and necessary business maintenance status; after the first failure, it will only be automatically checked again when the network is restored from unavailable to available. Transmitted during cold start check after consent; does not contain scripts, recordings or advertising logos

We mainly process information based on legal bases such as necessary to perform the service agreement with you, obtain your consent, and perform legal obligations. For information processed based on consent, you may withdraw your consent as described in this policy; withdrawal will not affect the effectiveness of the processing activities before the withdrawal.

3. Local content and AI Follow follow-up

3.1 Local documents and settings

Documents, groups, hotwords, annotations, display settings, prompt parameters, and reading positions are saved in the app's private storage space. The app turns off Android system cloud backup and device migration backup, and will not automatically synchronize these data to the cloud through system backup. Deleting a single document, clearing app data, or uninstalling the app will affect the corresponding local content. Please keep necessary copies before operating.

3.2 Import pictures and documents

The app does not request system permission to read the entire photo album or media library. Only when you select "Image document" on the document editing page and actively select an image through the Android system photo picker, the system will grant the app limited read permissions to the selected image. The app reads up to 10 of your selected images at a time to check file type, size, pixel dimensions and orientation, generate local thumbnails, adjust order, and recognize text on the device using the Chinese OCR model provided with the APK.

The original images are only read during the import process and will not be uploaded to our server or saved as document attachments for a long time. Only after you confirm the import on the preview page, the recognized text will be saved according to local document rules. You can cancel the system selector, skip images, or abandon the import.

3.3 Local speech recognition

AI Follow requires an account; you need to be online when logging in and starting the free trial. After entering the follow-up reading, the app calls the microphone to collect the sound of the current conversation, and uses the device's built-in Sherpa-ONNX model to complete speech recognition, text matching and scrolling control. The current session does not require an ongoing Internet connection, nor does it require documents or microphone audio to be sent to our servers.

3.4 Local diagnostic records

To help you reproduce the reading problem, the app can save evidence of up to three recent AI sessions in a private directory, with a total limit of 300 MB, which may include complete documents, hotwords, recognized text and tags, algorithm events, session configurations, and microphone audio. Once the number or space limit is reached, old sessions are automatically cleaned up. General diagnostic logs are retained for a maximum of 14 days and do not exceed a total size of 30 MB. The above information is only retained on the device by default.

4. Feedback and diagnosis sharing

"Feedback" is currently the only diagnostic sharing portal for users in the app. You can fill in a problem description, select up to 3 images, and choose whether to include an available AI session. The app won't send feedback for you in the background.

  • The selected image will be scaled and re-encoded in the app's private directory, and metadata such as original EXIF will not be retained; unfinished image drafts will be retained for up to 24 hours.
  • Diagnostic packages may contain problem descriptions, images, basic device and app information, general logs, and full transcripts, hotwords, recognized text, algorithm events, and microphone audio from the sessions you choose.
  • The generated share cache will be retained for up to 24 hours. You can cancel before opening the system sharing panel or not select a session that contains audio.
  • The diagnostic package will only leave the device after you choose to receive the app or contact in the system sharing panel and confirm sending. How the recipient subsequently handles the information is governed by its privacy rules.

If you send us a diagnostic package, we will only use it to process feedback, locate faults, improve the product, and ensure security, and limit who has access to the information. After the problem is resolved, we will delete or anonymize the relevant information when it is no longer needed or when the retention period required by law expires.

Please check before sending

Contributions and recordings may contain your or others’ name, voice, contact information, business information and other information. Please select only what is necessary to resolve the issue, and make sure you have the authority to provide the information to the recipient.

5. System permissions

The app will apply for or guide you to open permission when you use the corresponding function. Denying permissions required for non-basic functions will not affect functions such as document editing that do not rely on this permission.

authority or ability Purpose of use Impact of rejection or closure
microphone Collect the current voice for local AI Follow and corresponding local diagnosis You cannot use AI to read along, but you can still use Auto Scroll and manuscript editing.
Android system photo selector (non-whole library album permissions) It is up to you to actively select picture manuscripts or feedback pictures; the app can only read the pictures you select, and will not obtain permission to read the entire album or media library. After deselecting, this image import or feedback image attachment will not continue and will not affect other functions.

Local writing, editing and basic Auto Scroll can still be used

The foreground service is a system operating mechanism required by Android to continuously display the floating window or use the microphone. It does not mean that the app will continue to record when you do not activate the relevant functions. You can stop prompting, turn off permissions, or manage app permissions in system settings at any time.

6. Optional accounts and trading services

Account, AI Follow free experience, membership, redemption code and Alipay payment are online services and are only enabled when you agree to the current privacy policy and actively log in or operate the corresponding functions. You can still use local document editing and basic constant-speed word prompting when you are not logged in; AI Follow requires an account, and free trial rules are subject to the App page display. After entering follow-up reading, speech recognition, text matching and scrolling are still completed locally on the device.

7.2 Trusted processing and technical services

The official website and optional account services are deployed on cloud servers in China.

The app uses our self-hosted Countly Community Edition for the bounded behavioral analytics described above, not for ad serving or cross-app profiling. The public official website does not set advertising or analytics cookies. WeChat, QQ, SMS, and Alipay capabilities are invoked only when you actively use the related function after consent and are not used for advertising or profiling. If we add another service that processes personal information, we will update this policy and the third-party list first and obtain consent where required.

8. Invitation rewards, commissions and manual transfers

When you actively use the invitation reward function, we will process the invitation code, the internal identification of the inviter's and invitee's accounts, the binding time, the rule version, the reward issuance record, the first official member purchase result, the commission ratio and amount, settlement and refund correction records. Scanning the invitation poster will only open the official website download address; the invitation relationship will only be established when the invited user actively fills in the invitation code after logging in and the server verifies it successfully.

In order to prevent repeated collection, self-invitation, batch registration or payment identity abuse, we will use the installation ID, the anti-abuse summary of the bound third-party account and the payment identity summary verified by the payment channel for consistency verification. These summaries are saved using measures such as irreversible HMAC with independent keys. The client and customer service pages will not display the original third-party identification, original payment identity or specific risk control rules. Abnormal relationships, commissions or withdrawals can be restricted and entered for manual verification.

Before applying for manual commission transfer, you need to bind your WeChat account and mobile phone number, and submit your name that is consistent with your WeChat real name. Names are encrypted and stored, and mobile phone numbers are protected by independent encryption measures; customer service only views information within the scope required to perform real-name verification and register manual WeChat transfers, and the administrator is also the financial officer to review the amount, transfer voucher and statement. The backend uses named accounts, minimum permissions and operation auditing, and does not use shared administrator passwords. The SMS verification code is only used to confirm this withdrawal. Please do not provide the verification code to anyone.

The commission usually waits 30 days from the first successful purchase of the official membership by the invited friend; a full refund will offset the corresponding commission according to the event rules. The actual processing and arrival time of manual transfers depend on data verification, risk inspection, customer service processing, WeChat and other channels, and automatic or immediate arrival is not promised.

9.2 Security measures

We take risk-appropriate measures, including app private storage, disabling system cloud backup, transmission encryption, account credentials protected by Android Keystore, mobile phone number field encryption, access control, log desensitization, permission minimization, and security auditing. Nonetheless, no system can guarantee absolute security; when leakage, tampering or loss of personal information occurs or may occur, we will take remediation, reporting and notification measures in accordance with the law.

9.3 Cross-border provision
