Privacy Policy
1. Local Storage and Processing
All audio, video files, segment marks, and category tags are stored locally on the user's device. The app does not automatically upload, sync, or transfer any user content to the developer or third-party servers.
2. Recording and Personal Data
Certain features (such as Echo Method, Waveform Recording, Intensive Listening) use the microphone with user permission for local practice, analysis, and playback. Recordings are stored locally and can be deleted at any time.
3. Import and Export
Users can choose to export audio/video and segment records for backup or device migration. If exporting group information (MATE files), this includes filenames and category tags. When sharing with others, users should avoid exposing personal information.
4. Background Playback Permissions
When background playback is enabled, the app will continue playing audio or video in the background without collecting any other information.
5. Category Management and Cover Images
Users can customize categories and cover images for local display. Related image data is only saved on the device.
6. No Collection of Personal Identifiable Information
The app does not require account registration and does not collect names, emails, location data, contacts, payment information, or any personally identifiable information.
7. Third-Party Services
The app does not use advertising networks, analytics or statistical SDKs, and does not share user content with third parties.
8. User Control
Users can delete locally saved audio, video, recordings, and segment marks at any time. Import and export are completely under user control.
