Facebook tracks a scary number of details about you - here's how to find out everything it knows

Mar 21, 2018, 00:48 IST

To find out what Facebook knows about you, log in to Facebook and head to a page called "Your ad preferences" .

Facebook keeps track of anything you "Like" as you use its service. I apparently liked some page with an emotional message and now Facebook believes I will respond to "emotion."

Facebook also tracks what you do on the internet. Plus, every time you use Facebook to log in to apps on your phone it tracks that information. That's how Facebook learned I use Fandango on my phone.

If you're not brand new to Facebook, there are likely pages and pages of data on you.

After scanning all this stuff you do online, Facebook builds a profile about you, which you can see by clicking on "your categories." This is info Facebook shares with advertisers.

For me, it determined things about my family life, where I live, and what kind of tech I use. There is a lot of information about me that Facebook keeps track of and then uses to allow advertisers to target ads to people like me who share similar interests.

Not all of it is accurate. Facebook has labeled me as "very liberal" which is funny and a bit unsettling. My political views are moderate. You have the ability to cross out anything on the page, but it's not clear what impact that would have on ads, particularly political ads or fake news that target you, based on data that was previously gathered on you.

Facebook also tracks your location, meaning where you are and where you've been, using both Facebook and Instagram.

You can tell Facebook not to share your information with some advertisers but the only way to have Facebook NOT track any of your activities is to stop using its services, including the other apps it owns like Instagram. It's important to remember that Facebook is free because it makes its money by showing you ads.
