Emergency GPS Location Sharing

How emergency location sharing works

You send an SOS. The app asks your phone for a GPS fix. If it can’t get one within about 20 seconds, the alert isn’t sent and you’re told why.
A private link is created. Your contacts receive it in their alert. Only someone with the link can open it.
Your phone keeps sending updates. While sharing, it sends your position every few seconds when you move, and the contact’s map refreshes every 10 seconds.
You stop sharing. Press Stop when you’re safe. The link also expires on its own after 24 hours.

OneTapAlert uses your phone’s own location services. Accuracy depends on:

Permissions. Location access must be allowed for OneTapAlert. Precise location gives better results than approximate.
Surroundings. GPS works best outdoors with a view of the sky. Inside buildings, underground or between tall buildings it can be off by a lot or take longer.
Connection. Updates need data or Wi‑Fi. Without a connection, new positions can’t reach your contacts.
The app being open. Keep OneTapAlert open while you share. If you switch away or lock your screen, some phones pause location updates.

The contact’s map shows when the location was last updated, so they can tell if it’s stale.

No location is shared until you send an alert or a safety timer you set runs out.
Contacts can’t request your location or see where you’ve been.
Links expire after 24 hours at most.

Read the Privacy Policy for how location data is stored and handled.

If a safety timer expires, your contacts get a link with the last location your phone shared — even if your phone has since turned off.
