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.
