Write to apps@ake.dev — every message is read, and you will usually hear back within a day or two. ## Frequently asked questions ### Does QuakeLens predict earthquakes? No. Nobody can predict earthquakes, and QuakeLens never claims to. What it measures is statistics: when recent small-quake activity in a zone rises measurably above that zone's own long-term baseline, the zone goes into alert. An alert means elevated probability — similar to how seismologists describe aftershock risk — not a prediction. Most alerts are not followed by a damaging earthquake, and quiet activity does not mean an area is safe. ### Is QuakeLens an early-warning system? No. Early-warning systems (such as national services like ShakeAlert or AFAD's warnings) detect an earthquake that has **already started** and give you seconds before the shaking arrives. QuakeLens does something different: it watches activity trends over hours and days. If an official early-warning app is available where you live, keep it — QuakeLens complements it, it never replaces it. ### Why was there no alert before the earthquake in my area? Because most earthquakes strike without measurable warning signs. In our historical backtests, fewer than 1 in 10 large earthquakes overall — and about 3 in 10 in highly active continental regions like Türkiye — were preceded by unusual activity the detector could catch; the rest arrived out of nowhere. Each zone's report card in the app shows exactly which past earthquakes were preceded by an alert and which were missed. ### Why is my zone so large, or centered far from my location? Zones are drawn around fault systems, not cities. The earthquakes that matter to a coastal city on a subduction zone, for example, mostly happen offshore — so the zone must reach the seismogenic region, often 150–200 km away. A large circle is not imprecision; it is where the relevant activity actually happens. ### What does the free version include? The free app shows the full live status of one location — state, activity, and history, with alerts never hidden. QuakeLens Watch (a yearly subscription with a one-week free trial, or a one-time lifetime purchase) adds push notifications, unlimited locations, hourly charts, and widgets. ### How do I delete my data? Deleting the app is enough — the anonymous registration on our server is removed automatically. Details are in the privacy policy: https://quakelens.app/privacy --- QuakeLens reports elevated statistical probability based on measured seismic activity. It does not predict earthquakes — nobody can — and it is not an earthquake early-warning system. - Home: https://quakelens.app/ - Privacy Policy: https://quakelens.app/privacy
