Eliminate Surprises

Restrict App installation, deletion, and In-App Purchases.

After turning on "Disable App Installation", the App Store will not be able to open. If you click on the link to the App Store, it will only be displayed as shown below:

After turning on "Disable App Removal", when you try to delete an app you can only remove its icon from the Home Screen, but the app still exists in the App Library, which means the app is not deleted and can be searched or re-added back to the Home Screen.

After turning on "Disable In App Purchase", when trying to make in-app purchases, it will prompt "In-app purchases are not allowed."
