I tend to avoid to install apps that require permission for unnecessary internet connection.
I’ve used Tracker Control and for apps without internet access it says they still might track you by exchanging data with other apps.
How do you know if such thing is happening? I couldn’t find any related info online.
I’ve also used Immuniweb to test the level of security and privacy of apps. The last section of analysis is Mobile App External Communciation. Surprisingly some apps that don’t require internet access seem to connect to remote hosts.
Do you find it convincing?
I haven’t read the full report yet but would check that later.
