Facebook lets you manage your applications from the settings page. If you are searching for Application settings from your Account settings, it won’t be there. On Facebook, your name, profile picture, gender and networks are visible to everyone. Also, by default, apps have access to your friends list and any information you choose to share with everyone.
Step by step:
- Login to Facebook
- Click on Account tab from the navigation bar and hit the Privacy Settings link
- From the bottom of the page, choose Apps settings.
- Now that you are in the page, you can remove each of the apps by hitting the x mark to its right
- Confirm the removal and the application will no longer post in your wall.
