How do I edit the privacy settings for my timeline?

The visibility of posts you make on your own timeline depends on the audience you choose for each post using the audience selector. For example, a friend will see posts you've set to Friends and Public, while a non-friend will only see posts you've set to Public.

The visibility of posts others make on your timeline depends on the setting you've chosen for who can see posts by others.

You can remove an individual post whenever you want.

To control who sees stories that games and apps you use publish to your timeline, change your app privacy setting.
