Turn off Facebook apps


Q. How can I stop a Facebook app from posting on my behalf?

  1.  Go to your settings-->apps. Here's the link https://www.facebook.com/settings?tab=applications
  2. You will see all apps that are "logged in with facebook" and then it says "On Facebook, your name, profile picture, cover photo, gender, networks, username, and user id are always publicly available to both people and apps."
  3. Now click on the X for each app you want to delete.
