in november 2017, strava published a "global heatmap"—a "visualization of two years of trailing data from strava's global network of athletes." in january 2018, an australian national university student studying international security discovered that this map had mapped military bases, including known u.s. bases in syria, and forward operating bases in afghanistan, and hmnb clyde—a royal navy base that contains the united kingdom's nuclear arsenal. the findings led to continued scrutiny over privacy issues associated with fitness services and other location-aware applications; strava's ceo james quarles stated that the company was "committed to working with military and government officials" on the issue, and would be reviewing its features and simplifying its privacy settings.
