WiFi Manager

Privacy Friendly WiFi Manager helps you automatically turning on/off your
Wi-Fi while you are not near a known WiFi network. The app keeps track of
the cell tower ids in your area while you are connected to a WiFi network.
By keeping this information, the app tries to learn where your WiFi is
located without using GPS.

By switching off the device’s WiFi when it is not required, so-called
tracking via WiFi is avoided. Privacy Friendly WiFi Manager also saves
battery life by automatically disabling your device’s WiFi in case it is
not near an already known WiFi network.

The app preserves your privacy by tracking least necessary data. All data
is kept on your phone. No data is sent to anybody. We also try to use the
least permissions possible. Privacy Friendly WiFi Manager requires access
the the device’s coarse location to retrieve the cell tower information. It
furthermore requires access to the WiFi state and the permission to change
the WiFi state.

The app belongs to the Privacy Friendly Apps group developed by the
research group SECUSO at Karlsruhe Institute of Technology.
