Facebook conceived new tools after the Cambridge Analytica scandal to give users better control over their data privacy at the expense of advertiser positioning. When the user opens it, they will see the tracking user activity and send a report to Facebook on the list of apps and websites for advertising purposes. Clicking on the "Clear History" button will unlink this information from the Facebook account.
Users can also choose to prevent these apps and websites from reporting tracking data about users to Facebook in the future. Users can choose to disconnect all non-Facebook browsing data, or data for specific applications and websites. Facebook warns that users may see apps and websites they don’t recognize in their account activity, probably because a friend isMobile phoneLook it up, or because the user shares a home computer with a partner and child.
The Clear History tool was originally expected to be launched last year. But suffered a series of unexpected delays. Facebook will delay the two technical challenges, both of which are related to how Facebook is in itserverIt is related to storing user data, including Facebook data, which does not always store user data in the same way as collection, and also includes Facebook currently storing browsing data by date and time, rather than by user to which it belongs. This means that there is no easy way to view all browsing data linked to a single user in the Facebook system. Therefore, Facebook must build a new system for storing browsing data at the user level.
