The French army has warned about the risk of military information leaks when using everyday devices, from Tesla and BYD vehicles to smartphone applications (Tinder, Strava, etc.). This is because it is possible to photograph military facilities through vehicle cameras or track personal information using location services. In fact, the dating app Tinder has been used to track the movement routes of soldiers using triangulation, and the exercise logging app Strava has also resulted in cases where the location of French aircraft carriers was exposed. Recognizing these security vulnerabilities, the French army urged its personnel to be cautious and recommended turning off mobile phones as the best defense.
