Developer contact: contact+glyphbeat@pauwma.com
2. What data we collect & why
| Category | Source | Purpose | Stored? | Shared / sent off-device? |
|---|---|---|---|---|
| Media metadata (title, artist, album, playback state, cover-art bitmap) | Android Notification Access & MediaSession | Drive the animation (e.g. stop the vinyl when music is paused) | Kept in RAM only | No |
| User settings (selected theme, brightness, timeout, auto-start preferences, shake sensitivity) | In-app preferences | Restore your choices on next launch | Stored locally in SharedPreferences | No |
| Motion sensor data (accelerometer) | Device sensors | Detect shake gestures for track skipping (optional feature) | Not stored - processed in real-time only | No |
| Donation page traffic | External browser (Buy Me a Coffee, PayPal, GitHub Sponsors) | Process voluntary support payments | Handled entirely by the external provider | Not collected by the app |
Glyph Beat does not collect personal identifiers, location, contacts, or usage analytics, and never transmits your media metadata outside the device.
3. Permissions used
