It's no secret that Facebook collects information about its users, but you might be surprised to learn just how much the social network knows about you.
Here's a way to find out... and to stop it.
1. Go Into Settings
2. Click Ads
3. Click "Your Information"
4. Under "Your Information," Click "Your Categories"
As you can see, Facebook creepily knows all about you, using your activity on the site to pick up on everything from your family, your political views, your living situation and your interests.
It uses the information to help advertisers reach a more specific audience, but if you are freaked out by it, you can opt out any of the categories they assigned you to by clicking on the right side of each, where an X will appear.
