It is not shocking news that Facebook tracks you on its platform that's why it can resurface your birthday photos from five years ago  but you might not yet realize the scope and the depth of its tracking all across the internet. Facebook's tentacles stretch out across other website and services into the various apps you're using on your phone, and to the places you physically visit in the real world especially if you decide to check in on Facebook while you're there. Facebook's reach also goes way beyond Facebook itself.
