The social media giant in a 225-page document responding to a set of 2,000 questions by the US Senate Committee on Judiciary admitted that it collects information from and about computers, phones, and connected devices, including mouse, that users use with its various services and that it combines this information to give users a personalised content.
Tracking mouse movements also helps the social media giant, which has been under fire for its data privacy practices, to also determine if the window is foregrounded or backgrounded.
"We collect information from and about the computers, phones, connected TVs and other web-connected devices users use that integrate with our Products, and we combine this information across different devices users use," Facebook wrote in the document adding that the collected information is used to "give better personalize the content (including ads), to measure whether they took an action in response to an ad we showed them on their phone".
The company also admitted to collecting information about users' reported gender, people users have removed from their friend list and every ad the user has ever clicked on.
While the Facebook co-founder might not have admitted to recording audio snippets, in light of the recent information it has divulged, especially the part regarding tracking mouse movements, the company seems to be one step short of admitting the same.
