Facebook has reportedly signed all users up to its new privacy policy that lets the site track their activity on the internet even after they have left it.
According to the Independent, the change enables it to gather data from activity across the internet, as well as the normal data it gathers on information you and your friends have added to the site.
The new policy also enables the social network to pass on the information to Instagram and its other branches.
However, no data will be shared with WhatsApp.
The company said that it had informed users about the same and sent them emails, adding that the change would be implemented on January 30, the report said.
