Hide your home address from any activity file.

Most people start and end activities at home or near it. When you share the raw GPX with a friend, post it on a forum, or upload it to a route-sharing site, you are also handing out your home address - every trackpoint is GPS-accurate to within a few metres, and the cluster of points at the start tells anyone where you live. A 500m privacy radius removes those breadcrumbs while keeping the meaningful part of the ride intact.

Inside Strava, mostly - the privacy zone blurs the start and end of activities on the Strava map for other users. But the moment you export the GPX (or someone else exports your public activity), the full unblurred track is back in the file. Strava's privacy zone is a display layer, not a data layer. This tool modifies the file itself, so the protection survives any export.

Athlete name in the GPX metadata block. FIT device serial number, user_profile fields, and any optional personal-info fields. TCX author and creator fields. The scrub is optional - leave the checkbox off if you want to keep that info. Stats (distance, time, elevation, HR, power) always stay intact.

For sharing a route with friends, 200-500m is plenty. For posting a public route on a forum or a route-aggregator site, lean toward 500m or more, because anyone who downloads it might also be running scripts to find clustered start points across thousands of files. If you live in a quiet rural area where 500m only covers your driveway, go bigger.

No - the trimmed file is still a valid GPX/FIT/TCX. It will upload to Strava as a shorter activity, with the start and end trimmed to where you left and re-entered the privacy zone. If you want the full activity in Strava but want to share a trimmed version separately, upload the original first, then run this tool on a copy of the file for sharing.

Not directly. The Strava heatmap is built from activities uploaded to Strava, not from files you share elsewhere. To get off the heatmap, you need to mark activities private in Strava itself. This tool protects the file you share outside Strava.

Those stay intact - the point of this tool is to hide your home, not your route. If you also want to obfuscate the entire route, run it through our [Route Simplifier](/tools/route-simplifier) first to reduce points, or upload it as private to whatever platform you use.

Yes - the before-and-after map preview shows the full original track in one colour and the trimmed track in another, with the privacy circles drawn. You can drag the radius slider and watch the cut update live before downloading anything.
