How to uncover what Facebook knows about you
With nearly 3 billion monthly active users, Facebook can keep tabs on about a third of the world’s population. Whether you visit the social network daily (as 1.82 billion people do) or only log on to RSVP to events, you should be aware of how much of your personal data you’re giving to the site and the company behind it.
Facebook primarily uses your information to serve you more relevant targeted advertising. While some see this as uncomfortably intrusive, others accept the ads as the price they pay for the network’s free services and tools. Whatever you think about the ethics of this data collection, you should know just what the company is learning about you—and how you can control the flow of information. While this guide can help, there’s only so much you can do to protect your privacy—if you really want to stop Facebook from mining your data, your best bet is to delete your account.
