Delete my data

Your device profile isn't tied to your identity — it's a random ID plus the notification settings and alert location you chose. Deleting it removes that profile from our server and clears all data stored on this device. This can't be undone.

We never ask for your name, email or an account, and your privacy is our highest priority.
