Does it work with your kit?

No. Every head unit worth owning writes a .fit, .gpx or .tcx file, and an uploaded file is analyzed exactly like one that synced itself - same maps, same power curve, same climbs. A direct connection saves you the upload; it does not buy you a better ride page.

On sync means we fetch your rides whenever our next check comes round. Auto means the maker tells us the moment one exists, so it is here in a minute instead. Both are listed per device, because not every maker offers the second.

No. An archive import is a one-time move, not a connection - it brings across what exists on the day you upload it and then it is done. Run it again later and it adds what is new; it never rewrites a ride you have already edited here.

No. A ride is matched first by the provider's own activity id, then by the file's content hash, and only then by a fingerprint of start time, elapsed time and distance. So a reconnect re-links the rides you already have instead of making second copies of them - and that record is what lets you tell, years later, which bike computer captured which era of your riding.

Yes, and only you can. Once the provider is disconnected, a separate action behind a typed confirmation erases everything it brought in. It is never a side effect of anything else, and disconnecting on its own stops new data immediately without deleting a ride.

Connecting a bike computer is on the free tier. Wearables - recovery, sleep and strain - are a Pro feature.
