GPS Auto-Responder

Allow a trusted person to discover your location. You will be notified when your location is being shown.

The service itself does not keep any location data about its users and discards them shortly after displaying to the user. No registration required.

How it works: This app creates a unique link to find your phone from any web browser. The app will notify you each time, when the link is used by the person you shared the link with.

The app is extremely battery-efficient - it uses GCM so it runs only when the location is being displayed to the user.

Uses permissions:
* Your location
* Network communication
* Prevent phone from sleeping (GCM requires it)
* View network connections (to be able to renew link validity fom time to time when network is ready)
* Find accounts on the device (GCM requires it)

This app is open-source. You can download the source from:

To achieve ultimate privacy you can host the web service on your own server. The server code is also open-source and is available on:
