Understanding Facebook Privacy
Apps and games privacy
At some point, you may receive invitations from your friends to use Facebook apps and games. These are applications that let you interact with Facebook and your friends in different ways. A majority of these applications are created by third-party developers, not by Facebook itself.

When you use an app or game, you're giving it permission to do certain things with your Facebook account. This might include accessing your profile data, posting on your Timeline, and viewing information about your friends.

Although you can't use apps or games without allowing the requested permissions, most apps let you customize these settings after you've started using them. We'll explain how to do this in our lesson on Adjusting Your Privacy Settings.
