Your account
One name across it all.
A Cairn account is one claimed builder name. The game writes it into your capture filenames and your stream overlay, and it is what anything you buy is recorded against. It's lightweight by design — claim a name and you're in.
Accounts are a lightweight visitor identity — no password, no email. Claim a name and it follows you across Cairn on this browser.
Play without one
You never need an account to download and play, and nothing about the game depends on one. It's a name, and a record of what you own.

Subscribe to Cairn Cabins and your local worlds back up to your account, restorable anywhere. Not built in this reference build — the subscription is recorded through the free-mode gateway and nothing is uploaded.
