Does it work with your kit?
What connects today, which of the four things actually move, what is in development, and how to bring across the years you already have somewhere else.
Four things move. Two each way.
A connection is not one pipe. Two things come to you; two go out to the device in your bar bag. Not every device does all four, so every card and every row below spells out which.

Already have years somewhere else?
Bring it with you.
Every platform owes you an export of your own data. Ask for the archive, upload the zip, and you arrive with your history rather than starting again at zero.
Your Strava history, in one go
Ask Strava for the data export they are obliged to give you, then upload the zip here. Activities and their original files, photos and videos with their captions, your bikes and their component lists, your goals and your saved routes all come across - and each ride keeps the visibility it had over there.
We never touch Strava's servers to do it - it is your file, handed over by you, and we never ask for your Strava password. Multi-gigabyte archives are fine, and running it again later only adds what is new.
A move, not a connection. An archive is a snapshot of the day you export it; from then on, rides arrive through a connected device or an upload.
Device not listed?
Upload the file.
Every head unit ever made writes a .fit, .gpx or .tcx. Drag it in and it gets the same maps, power curve and climb detection. A connection saves you a step; it does not unlock anything.
.fit, .gpx and .tcx all welcome
Questions people actually ask
My head unit isn't on the list. Am I stuck?
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.
What's the difference between auto and on sync?
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.
Does importing my history keep it up to date afterwards?
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.
If I reconnect, will everything import twice?
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.
Can I delete what a provider imported?
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.
Does a direct connection cost extra?
Connecting a bike computer is on the free tier. Wearables - recovery, sleep and strain - are a Pro feature.
Bring the rides you've already done.
Connect a head unit, bring an old platform over, or drag in a single file. Your history gets here; it is yours to keep.
