Android has a powerful permission system that forces apps to declare the exact permissions they require — whether it’s displaying notifications, reading your contacts, or accessing your location. Controlling these permissions as a user is possible, but more complicated.

The permission system seems powerful, but there’s one big problem for Android users: By default, it’s a take-it-or-leave-it offer. You can choose to install the app and grant the permissions or not install it.
