Facebook Inc Chief Executive Mark Zuckerberg admitted on 11 April, Wednesday, that the social media network tracks activities of its users even after they have logged out.
Zuckerberg started his second day of testimony on Capitol Hill in Washington, facing more questions from lawmakers about data privacy at the world's largest social media network.
“We track certain information of people not signed on Facebook for security and ad information,” the internet mogul answered to a question raised by US Senator John Shimkus.
“We provide an ad network which third party apps can use and make money. So for that we also collect information so that those ads can work on those websites,” Zuckerberg claimed.
The 33-year-old billionaire was asked this question on the first day of hearing as well. He replied saying, “Senator, I want to make sure that I get this accurate, so it'll probably be better to have my team follow up with you on this.”
In the Wednesday hearing, Zuckerberg also told lawmakers that his own personal data was included in that of 87 million or so Facebook users that was improperly shared with political consultancy Cambridge Analytica.
But he pushed back on congress members' suggestions that users do not have enough control of their data on Facebook in the wake of the privacy scandal at the world's largest social media network.
Zuckerberg faced broad concerns from members of Congress about how Facebook shares user data.
