Tremor – Earthquake Alerts

Frequently Asked Questions

I'm not receiving earthquake alerts.

1. Check that notifications are allowed: iOS Settings → Notifications → Tremor.
2. Check your Focus / Do Not Disturb modes — they can silence alerts.
3. In the app, open your location's settings and review its alert level and range — only earthquakes at or above that magnitude and within that distance trigger alerts.
4. Check your quiet hours — alerts below your night threshold are muted during that window.

Does Tremor warn me before an earthquake?

No. Tremor is not an early-warning system. It notifies you about earthquakes that scientific agencies (USGS, EMSC) have already detected and published. For life-safety guidance, always follow your local civil protection authorities.

How is my location handled?

Your exact coordinates never leave your device. The places you add are stored on our servers only as a coarse ~5 km grid cell — enough to match earthquakes near you, and nothing more. See our Privacy Policy for details.

How do I manage or cancel my Tremor Pro subscription?

1. Open iOS Settings → tap your name → Subscriptions.
2. Select Tremor and choose the plan you want, or tap Cancel Subscription.

Subscriptions are billed and refunded by Apple, not by us.

I bought Pro but it isn't active.

Open the paywall and tap Restore Purchases. If it still isn't active, email us — we'll sort it out.

How do I delete my data?

Deleting the app stops all data collection. To remove your server-side data too, email privacy@alihanaktay.com and we'll delete it within 30 days.
