GPS elevation: fixed 5 m spatial grid, centered triangular smoothing over 20 m. Missing samples carry forward; leading gaps use the first known elevation. Repeated distances retain the last sample. Smoothing can soften short hills; these are not surveyed terrain measurements.
Your GPX is processed locally and is not uploaded. OpenStreetMap receives background-tile requests (including your IP and viewed area). Version switching does not transfer your private track.
