Your study data stays on your device.
HanziPro is an offline Chinese handwriting and vocabulary trainer. Your study data stays on your device unless you export it yourself.
What Data We Collect
None.
HanziPro does not collect analytics, telemetry, advertising identifiers, account data, location, contacts, or payment information.
What Data We Share
None.
HanziPro does not share user data with third parties.
What Data Leaves Your Device
Nothing leaves your device automatically.
The app can create files when you choose to export a full backup zip or a zip of vocabulary CSV files. Those files are handed to Android's system share or file picker UI. You choose where they go.
What Is Stored Locally
- Folders and vocabulary lists
- Words, pinyin, meanings, and notes
- Generated character review cards
- Writing attempts
- Review events and practice sessions
- App settings
Writing attempts are stored as stroke point data so the app can redraw them. They are not uploaded.
Offline Reference Data
HanziPro bundles Chinese dictionary data and character stroke data as app assets. These reference files are not personal data.
Backups And Deletion
- Export
- Use the app's Data screen to export a backup or CSV zip.
- Restore
- Restoring a backup replaces the current local study database with the selected backup.
- Deletion
- Uninstalling the app or clearing app storage deletes HanziPro's local database and settings from the device.
Exported backup files are ordinary files. If you save them to cloud storage, protect them the same way you would protect any personal study document.
