AstroBuruj — Privacy Policy
Last updated: 25 June 2026
AstroBuruj (“the app”, “we”) is an offline-first astronomy and Islamic-astronomy app for the night sky. This policy explains what data the app processes and why. We designed AstroBuruj to keep your data on your device wherever possible.
1. Data processed on your device only
- Location. With your permission, the app uses your device’s precise location to draw your local sky, compute prayer times, and point toward the Qibla. Your location is processed entirely on your device; it is not transmitted to our servers and not shared with anyone. You may instead set a location manually, or decline location access (the app falls back to a default city).
- Your settings. Language, theme, calculation method, and preferences are stored locally on your device.
2. Data collected by third-party services
The app includes Firebase Crashlytics (crash & diagnostics) to keep the app reliable: when the app crashes or logs a non-fatal error, it sends a crash report — stack trace, device model, operating-system version, and app version — to Google so we can fix bugs. The app uses no advertising or analytics SDKs.
This data is processed by Google as our service provider, under Google’s privacy terms. We do not receive your name, email, or location through this service.
3. Content the app fetches
The app retrieves read-only public content — officially declared Hijri dates,
regional crescent-sighting reports, and nightly sky highlights — from our server
(api.astroburuj.com) over an encrypted (HTTPS) connection. These
requests do not include your identity or your location.
4. What we do NOT do
- No user accounts or sign-in.
- No advertising and no advertising SDKs.
- No selling or renting of personal data.
- No third-party trackers beyond the Google Firebase services named above.
- No purchases or payment processing.
5. Data retention & your choices
On-device data (settings, cached content) remains until you clear the app’s data or uninstall it. Crash-report data is retained by Google per their retention policies. You can revoke location permission at any time in system settings.
6. Children
AstroBuruj is a general-audience reference app and is not directed to children under 13. We do not knowingly collect personal information from children.
7. Security
All network communication uses HTTPS/TLS. On-device data is stored in the app’s private storage.
8. Changes
We may update this policy; material changes will be reflected by the “Last updated” date above.
