I bought I device that is supervised. Does that mean they can view and steal my data
So I bought a used device and it looks like it supervised. They guy said it saved from ewaste. I understand the purpose of supervision and restricting devices but this one does not appear to be heavily restricted so far. I went to settings>general> and then there is not even an option for "Profiles & Devices." I also tested a website that should be restricted and it worked fine.
I want to test downloading apps etc but I am hesitant to sign in with my apple id. I know supervision can restrict access, but does it allow allow a 3rd party to view all of my stuff, websites I view, keystrokes, etc? That is what I am really worried about. Or is this a thing where if the supervision is not intrusive, it just shouldn't really matter to me? I'm trying to figure out if I should make a big fuss about this purchase or not. Thanks for any insight!
