We all use Google services as they make our lives easier. But, did you know that Google is tracking your every movement? It is understandable when the location service is on or the phone is connected to the internet. But, in a shocking experiment, two identical phones were carried around all day without having connected to the internet and one of them was in the airplane mode.
At the end of the day when they were connected to the internet they sent data to Google which accurately tracked the location of where the phones were carried throughout the day. What was more surprising was the fact that the phone on airplane mode saved more locations than the one that was not.
