MAstroAlarm — Privacy Policy
Last updated: May 2026
1. Data Collection
MAstroAlarm collects only the alarm data you create: alarm type, scheduled time, and city/coordinates. This data is stored locally on your device using Room database.
2. Location Data
If you enable GPS, the app requests your device location to set your default city. Location data is used only for astronomical calculations and is never transmitted or stored in the cloud.
3. Account Data
If you sign in with Google, your account name and email are stored in Firebase Auth for cloud backup only. Sign-in is optional — all alarm features work without an account.
4. Third-Party Services
Firebase Auth (optional, for backup). RevenueCat for in-app purchase management. Google Play Billing for payment. Swiss Ephemeris runs locally — no external API calls for calculations.
5. Offline Operation
All astronomical calculations use Swiss Ephemeris running on-device. No calculation data, alarm times, or location information is sent to any server.
6. Data Retention
Local alarm data stays on your device until you delete it. Cloud backup data is retained while your account is active.
