How Facebook spies on you and how to stop it
Here are some tips to disable data utilized by the Apps on Facebook:
From a computer: log into Facebook, click on the triangle in the top right hand corner of your browser, then Settings, then Apps.
Disable Apps from accessing your data such as friends, photos, and private information.
From your cellular device/tablet: open Facebook, click on the 3 horizontal lines in the bottom right hand corner to open your “Options”, scroll down to “Settings”, select “Account Settings”, then scroll down and select “Apps”.
Once you are in Apps and Websites, you can disable Platforms that allow apps to interact with your Facebook Account. Then disable the option “Apps others use”.
