App Permissions: Why Does a Torch Need Your Contacts?

Apps ask permission to use parts of a phone: camera, microphone, location, contacts and photos.

Some apps ask for far more than they need, and the data can be used for adverts or worse.

The single best question is: does it need that to do its job?

Location deserves special care: photos and apps can reveal home, school and routines.

The rule from the episode: only say yes to what the app needs.
