Ever take one of those Facebook quizzes to find out which superhero most resembles your dog, or have a friend who seems to spend most of their life doing so? Then you might be in for a surprise when you take this quiz and learn just how much of your personal information these quizzes can access.

Even if your Facebook profile is “private,” when you take a quiz, an unknown quiz developer could be accessing almost everything in your profile: your religion, sexual orientation, political affiliation, pictures, and groups. Facebook quizzes also have access to most of the info on your friends’ profiles. This means that if your friend takes a quiz, they could be giving away your personal information too.

But don’t take our word for it – take this quiz and see for yourself!

(And, yes, we know it’s a little weird to warn you about Facebook quizzes by asking you to take a Facebook quiz – but at least you know who we are and that we have a real privacy policy that we’re committed to upholding. Can you say the same for every unknown author of every quiz you or your friends take?)

It’s amazing what information a quiz/application can collect from your profile.

You can change what information is available by going in Privacy –> Applications.
