Strava's Heatmap Feature Raises Privacy Concerns

Researchers at North Carolina State University Raleigh discovered that Strava's heatmaps can reveal users' home addresses by merging publicly accessible heatmap data with unique user metadata. The researchers were able to identify individual residential addresses by locating starting and ending locations near specific homes and comparing the findings with voter registration data. To ensure privacy, Strava users can hide the start and finish of their activities within the app's privacy controls.
