Facebook is making its “Off-Facebook Activity” tool, which allows users to manage and delete the data that third-party websites and apps share with Facebook, available to all users worldwide. The feature was first introduced in 2018 at Facebook’s annual developer conference, but only launched to users in select geographies last year.

When the tool was initially announced in 2018, it had a much more user-friendly name — “Clear History.” But Facebook believed that could confuse users who may think that the tool had something to do with wiping out their Facebook data published to the social network itself. The new name is meant to better clarify what kind of data is getting deleted — “Off-Facebook Activity.”
