Privacy Preserving Proximity

PCube was the first location-aware app that alerts you about the proximity of your friends without acquiring your location data.

The app was available for Android as well as iOS, however the project is currently suspended. For this reason the server is down and the PCube service is not currently available.

PCube description:
By connecting to Facebook from PCube, you can be notified about the proximity of your Facebook friends (iOS version only).
