Facebook - Protecting Your Information

Posts

Whenever you update your status, share photos or post anything on Facebook, you can select who sees what you share by using the "Audience Selector" tool. You can choose to share with everyone or just your friends. Remember, when you post something on another person's profile, that person controls who can view the post and anyone who is tagged in your posts may see them, along with their friends.

Profile

When you log in to Facebook on a computer, you can see what your profile looks like to other people by using the "View As" tool. To use "View As", click on your profile, click "View As..." and follow the on-screen instructions. Using the tool, you can see what your profile looks like to the public or to a specific person.

Tagging

Tag review and Timeline review are options that help you control who sees what you post and what posts appear on your Timeline. Tag review lets you keep or remove tags that friends add to your posts. When you decide to keep a tag, the person tagged and their friends may see your post. Remember that when people you aren't friends with tag you in a post, you're  asked to keep or take away the tag.
