Drop a ski day here: a GPX, FIT or TCX file from your watch or phone. For a Garmin, the FIT from Garmin Connect has the most detail.
The file stays on this device. To find the resort, only one point rounded to about a kilometre and the date are sent. Heart rate in the file is not read unless you say yes.
Open the whole day from the start in Flyby, or replay it on the mountain in the Snow Globe.
Fly it shows your day on map pictures from Esri, EOX, OpenTopoMap and national mapping agencies. Your browser asks them for the map squares around your day, so they see your internet address and roughly where you skied, but not your file.
Built in your browser. Only one rounded point and the date left this device, to find the resort and its conditions.
