Google ‘Apple Watch saved my life’ and you will be met with a raft of stories about how the eponymous wearable computer detected an undiagnosed heart irregularity or dialled emergency services when its wearer experienced an accident or health incident. These features are made possible by collecting large amounts of very personal data about the user: blood pressure, heart rates and precise GPS locations, for example.
While GPS location data is very helpful, potentially lifesaving information for an ambulance crew, it must be remembered that the same data could be very dangerous in the wrong hands — such as those of an abusive ex-partner, for example.
