The Privacy Risks of Strava's Heatmap Feature
Strava's global heatmap feature, which is based on GPS data and compiles data from the previous two years, could reveal user locations, even on private mode, according to researchers at North Carolina State University. The feature could pose a privacy and safety risk to Strava's more than 100 million users, as it could expose secret or sensitive information through its global heatmap. Strava has provided an opt-out function for the heatmap after discovering the risk. However, researchers found that making an account private doesn't guarantee protection against this.
