Whole run & recording notes
Smoothed GPS elevation: fixed 5 m grid, centered triangular smoothing across 20 m. Missing samples carry forward; leading gaps use the first known elevation. Duplicate-distance samples use the last value. Edge samples clamp. This can soften short hills; it is not surveyed terrain.
GPX parsing and analysis stay in this browser. Opening the map requests external OpenStreetMap tiles, which disclose your IP and viewed map area. No location permission, GPX upload or cross-version transfer.
