Strava suggests military users 'opt out' of heatmap as row deepens

Fitness-tracking company suggests secret army base locations were made public by users, while militaries around world weigh up ban

Fitness-tracking company Strava has defended its publication of heatmaps that accidentally reveal sensitive military positions, arguing that the information was already made public by the users who uploaded it.

Following the revelations, militaries around the world are contemplating bans on fitness trackers to prevent future breaches. As well as the location of military bases, the identities of individual service members can also be uncovered, if they are using the service with the default privacy settings.
