Facebook has been in the news a ton over the last few weeks because of their data usage practices.

Thanks to IFLScience.com we know how to disable these features, but here's exactly why you should:

"Most people forget that when they download an app or sign into a website with Facebook, they are giving those companies a look into their Facebook profile. Your profile can often include your email address and phone number as well as your work history and current location. And most people don't realize that if you're sharing that data with friends, then apps used by those friends can see that data as well! Advertisers, Facebook-app developers, and Facebook ad-tech partners can't see your name, your phone number, or your employer – Facebook encrypts and anonymizes all the data to protect your privacy. But it does sell that data in bulk to companies who want to target and track both you and people like you."

With all of that in mind, the video above will walk you through how to stop these apps from tracking you.

You'll also have the option of turning off the function that allows you to log into websites using your Facebook account.
