You can put parental controls on most everything. I know that it has happened on games and songs on my just regular old phone and I'm the only one that uses it. I am continually getting some kind of miscellaneous monthly charge. And "customer service" just can't quite figure out how it got on there. If I don't catch it on the first or second charge, they won't refund all the charges; just a couple of them. HUH? But I never authorized it!! I think all this is just another way to make money for the apps creators.
PS: My 1 year old grandson knows how to manipulate his parents i-phones!! He loved computers and phones. :)
