Facebook Admits It Collects User Data Even From Non-Users

After the US Congress questioned Mark Zuckerberg about Facebook’s tracking of users personal data, the social networking company revealed that it collects data even if users aren't logged in and even collects data from non-users for security purposes.

Zuckerberg explained that Facebook collects data beyond what users share on their profiles. He said, “In general we collect data on people who are not signed up for Facebook for security purposes.”

“When you visit a site or app that uses our services, we receive information even if you’re logged out or don’t have a Facebook account,” wrote David Baser, Facebook's Product Management Director in a blog post on Facebook.

Baser said “many” websites and apps use Facebook services to target content and ads, including via the social network’s like and share buttons, when people use their Facebook account to log into another website or app and Facebook ads and measurement tools.

He stressed the practice was widespread, with multiple companies such as Google and Twitter and many more, “Most websites and apps send the same information to multiple companies each time you visit them.” 

“There are three main ways in which Facebook uses the information we get from other websites and apps: providing our services to these sites or apps; improving safety and security on Facebook; and enhancing our own products and services."

Baser reiterated that Facebook does not sell people's data.
