Android (NASDAQ: GOOG) owners using the Facebook Messenger (NASDAQ: FB) application to chat with friends and send silly stickers could be having their location tracked by the social media platform without even knowing it. While the application is open and the user is chatting in a specific window, the default setting is for the message to be accompanied by a location tag. This feature can be turned off by selecting the compass, according to CNN Money. This default feature was first discovered by Harvard Professor Aran Khanna, who used the application to plot location points. "The latitude and longitude coordinates of the message locations have more than 5 decimal places of precision, making it possible to pinpoint the sender's location to less than a meter," Aran Khanna wrote on his blog. "It seems so harmless to attach a location with a single message, but the problem is over time the information from these messages adds up." For more technology and business news, click here.
