App Permissions

To help you in an emergency, this app needs a couple of permissions. Here's exactly what's used and why:

Location

Used only when you activate the emergency location feature. Coordinates stay on your device and are never stored. Tap "Open Map" to send them to Google Maps so you can identify nearby streets or landmarks for the dispatcher.

Phone / Call

Emergency call buttons open your phone's dialler directly so you can reach services with one tap. No calls are made automatically.
