PRIVACY

You don’t necessarily want your personal data accessible to every app that asks, and iOS is here to give you the kind of fine-grained control that you crave. Under the Privacy section of Settings you can not only adjust which apps have access to your location, but also prevent them from accessing your contacts, calendars, reminders, photos, and Bluetooth sharing. Plus, if you use Twitter or Facebook, you can decide which of your apps can log in with your credentials. Just tap the appropriate section for any of these and slide the switch for the selected app to Off.
Restrictions. Go to General and then to Restrictions. You’ll be prompted to enter a passcode. You can then select which features you would like to lock down on your iOS device. If you’re planning to hand the iPhone off to Junior, and Junior has a habit of unintentionally deleting your apps, you can specifically disable that capability from the Restrictions screen. You can also prevent access to the iTunes Store, the iBookstore, Safari, Camera, FaceTime, and more.
