Learn how to control the privacy settings for timeline applications on Facebook.
When you click on the application from the Facebook timeline application directory, you’ll often be taken to the application website and asked to log in. Then you’re directed to the application approval page from there.
You only need to approve the application once to ensure your information is shared in many different places. This makes it easy to set up, but it might come as a surprise to some. If you already use the application, you’ll need to re-approve use to enable the timeline application, but the custom sharing settings you’ve previously set for that application will be maintained.
