The 18 Things You May Not realise Facebook Knows About You

The creepy ways Facebook spies on its users have been detailed in a bumper document presented to Congress.

They include tracking mouse movements, logging battery levels and monitoring devices close to a user that are on the same network.

The 454-page report was created in response to questions Mark Zuckerberg was asked during his appearance before Congress in April.

Lawmakers gave Zuckerberg a public grilling over the Cambridge Analytica, but he failed to answer many of their queries.

The new report attempts address their concerns, but it sheds little new light on the Cambridge Analytica scandal.

However, it does contain multiple disclosures about the way Facebook collects data.

Device information

Facebook tracks what device you using to access its social media.

To do this, it will log the hardware manufacturer of your smartphone, connected television, tablet, computer, or other internet-connected device.

Facebook also tracks the operating system, software versions and web browser.

If you’re using a smartphone, it will also keep a record of the mobile carrier, while internet service providers (ISPs) will be stored for users using a Wi-Fi or Ethernet connection to access Facebook.

Mouse movements

Facebook watches the movements of your computer mouse on-screen when you are interacting with the social network.

The company says it does so to help fight against bots on the social network. How to Disappear: Eras... Frank Ahearn, Eileen H... Best Price: $2.80 Buy New $8.51 (as of 05:35 UTC - Details)

App and file names

Facebook keeps a note of the file names in your system for the same reason.

This data is synced with your profile, and will influence the types of advertisements you see when you launch Facebook.

Device operations

Facebook wants to learn about how you use its social network.

To do so, it records whether you keep your Facebook browser window at the foreground of your computer screen – or whether you tend to leave it in the background, hidden behind other windows.

Facebook also watches the ‘operations and behaviours performed on the device’ while you’re active on the social network.
