The US Department of Defense has banned employees from using GPS trackers on government and non-government-issued devices when on duty in operational or top secret locations around the world. These devices include fitness trackers, smartphones, tablets, smartwatches and any software application that can track movement. Exposing employees personal information, activity and location could jeopardize military foreign missions and homeland security. The memo recommends thorough US personnel training to properly use GPS technology without leaking data about themselves or confidential operations.”]
