Facebook Chief Executive Mark Zuckerberg used Data Privacy Day on Tuesday to give details about a new feature designed to give people more control over how they are tracked by the social networker across the internet.

Zuckerberg used a Facebook blog post to say the Off-Facebook Activity tool is now available to all of the company’s approximately 2.4 billion users worldwide. Facebook originally announced plans for the tool in 2018, which it called “Clear History” at that time.
