Thanks, I found it: https://git.dryusdan.fr/Dryusdan/garmin-to-fittrackee

I’ll check it out!

Unfortunately Garmin does not offer their API to private consumers: https://developer.garmin.com/gc-developer-program/program-faq/

I have not found a way to pull the data without API access.

Recording is currently not possible with wanderer itself. I personally use osmAnd to record my trails and import them into wanderer. If you don’t want to expose wanderer to the public your friends would need to send you their trails, yes. But I guess that’s no different with any other service.

Currently, it creates a new trail every time. I agree that the name is a bit unfortunate. It was fitting when wanderer started out because back then it was solely made for hiking. I plan to transform summit logs into leaderboards similar to strava in a future update. Then I will probably also rename the summit logs to something more fitting.
