GRIND

1. Data Storage

All your data — challenges, routines, habits, streaks, stats — is stored exclusively in a local SQLite database on your device. Nothing is sent to any server. We have no access to your data.

2. Camera & Photo Verification

GRIND uses your camera for optional photo verification of habits. Photos are analyzed entirely on your device using TensorFlow.js and MobileNet. No image ever leaves your device or is uploaded to any server.

3. Notifications

GRIND sends local push notifications to remind you of habits. These are processed on your device only and are not shared with third parties.

4. Crash Reports (Optional)

GRIND optionally uses Sentry for anonymous crash reports. This is disabled by default and can be enabled in Settings. If enabled, only technical error data is sent — no habit content or personal data.

5. Third-Party Libraries

GRIND uses TensorFlow.js, MobileNet, and Capacitor — all run locally on your device. No personal data is shared with these libraries.

6. Backup & Export

You can export all your data as a JSON file at any time. Exported files are stored locally. Sharing them is your responsibility.

7. No Account Required

GRIND requires no registration and collects no personal information like email addresses, names, or phone numbers.

8. Data Deletion

Uninstalling the app removes all data. You can also reset all data from within the app settings.
