Permissions are access rights an app asks to access on your phone.
They can concern various features or pieces of information, such as access to your geolocation, your contacts, your files, your microphone, vibrate function, camera and so on. Exodus Privacy analyses allow you to know, on a per app basis, which permissions are asked.
Google defines danger levels for permissions, which we report in our analyses.
Depending on your smartphone and operating system, it is possible to restrain some of these permissions by going into your phone's settings.
