What You Can Do About Facebook Tracking

Here are four cold, hard realities of Facebook's privacy policies -- and what you can do about them right now:

1. You can't stop receiving ads on Facebook -- but you can keep Facebook from aiming specific ad topics at you.
2. As long as your browser keeps cookies, you can't stop Facebook from tracking you according to age, gender and where you live. But you can stop it and other companies from using that information to deliver ads.
3. You can stop Facebook from knowing your phone's location and limit it from using other information to target ads.
4. Unfortunately, all of these rules could change later.
