Copy link puts your measurements and bikes into the address itself, so you can send a fit to a friend, a bike shop or your other device without an account or an upload.

Opening a link on a device that already has data asks first, and Keep mine leaves your own setup untouched.
The link only carries what you typed. Values the tool assumed, such as an unknown spacer stack, are rebuilt at the other end.
Repeat readings stay on your device. The range they produced travels, the individual measurements don't.

A link carries your body measurements, so share it only with people you want to see them. Export JSON is still there for a full backup, including saved scenarios.

Share a fit with a link.
