I don't make Apple apps but I think this is a good idea. I don't provide a way for a user to delete their data in my app but that's because I don't want to have to deal with having to tell them "You shouldn't have pressed that button". But I'll gladly delete it they request I do. That's a tough one to balance though. It's been very rare but I've had users call me a few years after their account expired asking if I still had their data, and in all those cases I did, and that saved their butts because they needed it. In my case storing user data is very inexpensive so unless they ask me to delete it I'll let it sit for long time. What's happened more often is I'll have users try to login and then renew their accounts after they've sat for over a year.
