Facebook has updated its privacy policy to say that it can now track your every move, even when you're logged out of the app.
Facebook's latest policy change will come as a knife in the heart to the privacy-aware, as the new policy allows the website to gather data about you from across the internet, including online searches and details shared with online retailers.
A Facebook spokesman explained: "It takes into account pages and places visited on Facebook, alongside browsing on the internet at large."
Facebook, of course, claims this is a good thing, and that it will improve the user experience by showing only relevant adverts.
The saving grace is that you can opt out for some parts of the new policy by customising the privacy settings.
