KEY POINTS
  • Facebook knows everything you've ever done on the social network, like what you've posted, whom you're friends with and where you've been.
  • You can download a copy of your Facebook information, so we'll show you how. Facebook recently made the process a lot easier.
  • Then, if you want, you can delete your account permanently and keep a copy of everything you'd ever posted to Facebook. Here's how.
Facebook CEO Mark Zuckerberg

Facebook knows an awful lot about you. In my research digging into what Facebook knows about me, I've found that it has a copy of every comment I've ever posted, every message I've sent, anything I've ever searched for, a log of exactly where and when I logged into my account and much more. It's an astounding amount of data.

There's good reason to worry about your private information being left in the company's hands. Facebook hasn't managed to keep its user's info secure. A security breach just last month, for example, exposed the private information of 30 million accounts. Of those 30 million, hackers gained access to 14 million accounts' phone numbers, email addresses, gender, relationship statuses, recent check-ins and more.
