How to quickly find out which apps are using your user info, and shut it down

By TATIANA PROPHET

I have been sharing Facebook info – real info like photos and birthdate – with 98 digital applications, and I had no idea. That my birthdate was being shared with app developers was especially annoying; on my Facebook “proper” privacy settings, my birthdate is visible only to me. Yet there are 98 apps, including Five-Star Slots, Ancestry and Flixster, that have access to my birthdate, my work history, my political persuasion and my photos.

Do you know where your data is? I thought I knew. But since I joined Facebook 10 years ago, the places I consented to leave my data have now faded as quickly as where I went for lunch last week.
