Privacy

Short version: we do not want your data. This site works without accounts, sign-ups, or tracking.

What we store

If you turn on alerts for a city, your browser creates a push token: a long random address used to send notifications to your device. We store that token so we can send you alerts, and nothing else about you. If you turn alerts off, we stop using it.

Your choices, like which cities you subscribed to, are saved in your own browser, not on our servers.

What we do not do

No advertising. No analytics trackers. No selling or sharing of personal data. We do not ask for your name, email, or location. The map can show a "you are here" dot if you allow it, but your position never leaves your browser.

Services we rely on

The site runs on Google Cloud. Maps, translation, spoken audio, and notifications are provided by Google services, which process those requests under their own terms. The hazard data itself (earthquakes, rivers, weather) is public information about places, not about people.

Removing your data

This is a demonstration project with no accounts and no support desk. The only thing tied to your device is the push token described above, and it lives only while alerts are on. To remove it yourself, turn alerts off for your cities, or clear this site's data in your browser settings: that deletes the token and every choice saved locally, leaving nothing of yours on our side.
