Arch + KDE does that

As an Italian, it's even funnier cause "sega" means handjob

Because the request's payload actually contains a json with the sql property.

I understand. Currently, I'm using the NextCloud's extension Phonetrack, and one on my main use cases is to export GPX files to use them in Darktable and add geotracking information to the pictures I shoot with my camera. It works well, actually, but Phonetrack is not too intuitive and does not offer many other features: that's why I was looking with interest at this alternative!

Very very cool! I see that you can import GPX files: can you also do the opposite, i.e., export a GPX file for a selected time range?

I tried both the OwnTracks server and Dawarich, and had problems using them with my reverse proxy (Caddy), which I didn't manage to fix. Eventually, I installed the Nextcloud app Phonetrack, and I've been using it for months with the OwnTracks client: it works fine, it can also export GPX files, which I can use to tag pictures shot with my camera, using Darktable. I recommend this solution if you are already using Nextcloud!
