Facebook Can Pinpoint Your Exact Location Down to Location in a Room — RT News
If you value privacy, you may want to think twice before using Facebook Messenger. A new extension for Chrome has revealed just how much location data is shared through the app – and it’s enough to track someone down with almost perfect accuracy.
The extension – called the ‘Marauder’s Map,’ after the magical map in Harry Potter – pinpoints the locations of a person’s Facebook friends. It allows a person to track their movements, learning about their routines and weekly schedules.
Though some may view the information as useful, others think it is downright creepy, as it hands over a person’s movements on a silver platter to any potential stalkers.
Khanna developed the extension after noticing that Facebook Messenger locations had more than five decimal points of precision – meaning the sender’s location was pinpointed within three feet (one meter) of accuracy.
By testing his map on a group of Facebook friends who posted on chat at least once a day, Khanna realized he could see where one of them lived – even down to the exact location of his dorm room
