Consider what the route reveals
The beginning of a recording can identify a home, workplace or another sensitive place. Removing a fixed number of first points is unreliable because recording intervals vary. A loop may also return to the same place halfway through the activity, leaving the location visible even after a simple start/end trim.
The privacy operation creates spherical zones around the current endpoints of the tracks you select. It applies those zones to every track in the working file, removes fixes inside them and separates retained runs when an edge would cross a zone. The tool never inserts a replacement coordinate on the zone boundary. Applied zones remain in local memory for subsequent point deletion and simplification; new crossing edges are separated again. Those zone centers are not included in downloads. Reset restores the original local recording and clears the zones. Review the resulting shape because sparse recordings can lose a complete crossing edge.
Remove hidden location context too
Coordinates are not the only identifying data in GPX. Names, timestamps, waypoints and vendor extensions can contain places, exact activity times or custom coordinate fields. The default privacy option strips those categories along with point and segment extensions. Keeping them is an explicit choice and can reveal information that the visible route preview does not show.
The edited GPX, KML, CSV, SVG and change report contain the resulting working geometry. Original source files and removed endpoint coordinates are not bundled into these downloads. Undo restores the previous local working copy, so prepare fresh exports after undoing or resetting an edit; earlier download links are cleared when the working route changes.
Review the entire result before publishing
Endpoint zones are a useful removal tool, not a guarantee of anonymity. A route can reveal a familiar street, repeated meeting point or recognizable pattern away from its endpoints. A small radius may also leave enough geometry to infer where the recording began. Inspect the complete route and choose a different sharing approach when location sensitivity requires it.
Check a downloaded file in the destination viewer and confirm its point count and metadata. The preview uses an approximate local projection and the zone test uses a mean-radius sphere, so it should not be interpreted as a legal boundary or precision survey. No external map service receives the coordinates during editing, and no missing private section is reconstructed.
