Let's take Instagram for example. You give it permission to access your gallery because of course when you try to add a picture, it will need to access the file system in order for you to upload one. That's fine. But can someone at Instagram look through your gallery without you even knowing? Can they see every single picture you have whenever they want, or can they only see the pictures at the point of upload?
I was just curious about this and can't seem to find a definitive answer online.
