Dad installed phone sherriff on my iphone?

How do i deactivate or uninstall this successfully. I'm 17 and it doesn't really make sense to me why he needs to know everything i'm doing

As I said before: when you pay for the phone, you get to make the rules.

Nothing you can do as he owns the account and phone. If you want to start paying all your own bills then you will own the account.

When your 18, you can get a phone in your name but until then learn to deal, cope, and adjust. Most teens think they know Four times what they really do, sorry dude.

Easy, just pawn the phone and buy a new one.
