Data is refreshed every 5 minutes from multiple seismological agencies including AFAD, Kandilli Observatory, USGS, EMSC, JMA, BMKG, and others. The app list updates automatically on your screen.

Check the following: (1) Notification permission is granted in your device settings for the app. (2) Battery optimisation is not restricting background activity. (3) You have an active internet connection. (4) Your notification filters (magnitude, radius) are not set too strictly.

Premium unlocks: (1) Location-based notifications — get alerts only for earthquakes near you. (2) Priority processing — your device receives alerts faster. (3) Advanced filters — filter by magnitude, depth, country, and time range. Plans are available monthly, quarterly, and annually.

Subscriptions are managed entirely by Google Play or Apple App Store. To cancel: on Android, go to Google Play → Subscriptions → Deprem Uyarı Sistemi X → Cancel. On iOS, go to Settings → Apple ID → Subscriptions. Cancellation takes effect at the end of your current billing period.

No. Location access is entirely optional. Granting location permission enables personalised proximity-based notifications, but the app is fully functional without it — you'll still see all earthquake data globally.

The map uses OpenStreetMap tiles which require an internet connection. Try: (1) Check your connection. (2) Force-close and reopen the app. (3) If on a restricted network (school, corporate VPN), the tile server might be blocked — try switching to mobile data.

We aggregate data from official seismological agencies. Accuracy depends on the source agency. Early reports may be revised as agencies refine measurements. Always refer to official civil protection authorities for emergency decisions.
