Privacy policy

Last updated: 12 November 2026

In short

We keep as little as possible. A report holds a locality and an intensity. No exact location, no name, no phone, no tracking cookies, no ads.

"I felt it" reports

• Saved: the locality you picked, the intensity, the time, the site language, and an optional short note after an automatic check.
• If you use "my location", the nearest locality is found on your device. The coordinates are never sent to us.
• One report per device per quake: your browser keeps a random code; we store only a one-way hash of it together with the quake, and we delete that hash after 30 days.
• Against abuse: a one-way hash of your network address with a salt that changes every day, deleted after 24 hours. The address itself is never stored.
• The locality, intensity and time stay as anonymous statistics. Notes are deleted after 90 days.
• Bot check: Cloudflare Turnstile checks that the sender is human, without cookies for tracking (see Cloudflare's privacy policy).
• The "How strong was it where I am?" box sends only the code of the locality you picked and nothing is stored on our side. The last locality is kept only in your browser, to offer it again.

Alerts

If you turn on alerts, we keep the push address your browser gives us, the threshold and the language, until you turn them off or the browser cancels the address. Messages pass through your browser's push service (Google, Apple, Mozilla or Microsoft).

Visit counting

Cloudflare Web Analytics counts visits anonymously, without cookies and without identifying you.

Map

Map tiles load from OpenFreeMap, which receives the usual technical request details (such as the network address) to serve them.

Ideas and bugs

Messages from the feedback page go to the server of our sister app Tension index and are kept for up to a year.
