Strava’s heatmaps may not be as anonymous as you think.
Strava’s heatmaps can be handy if you’re scoping out new running, cycling, and hiking routes, as it helps visualize popular areas. However, researchers discovered they could reverse-engineer where a Strava user lives — even though heatmaps are created through anonymized, aggregated data.
You can read through the findings (PDF), but essentially, the more active the user, the easier it was for researchers to find their home addresses — especially in remote areas. If that creeps you out, go to Settings > Privacy Controls > Aggregated Data Usage to opt out.
