The current case is about the wearable app of Finnish navigation and sports watch experts Polar : According to Mashable, this not only records the running and cycling data of athletes, but also shared the location of British intelligence agents of the MI5, MI6 and Gouvernement Communications Headquarter (GCHQ). Journalists from the Dutch news sites De Correspondent and Bellingcat came to this conclusion, having specifically researched whether, in addition to Strava, other fitness apps would reveal the whereabouts of soldiers or secret agents.
