No form and no hard questions. Cancellation is done on the Creem portal, and the plan stays active until the end of the paid period.
After that the machine goes back to Basic FREE: measuring continues and nothing on your computer is deleted.

What this account knows. And what it'll never see.
HarnessUp runs the official claude and codex with your account and never reads, stores or passes on your token or your key. The site account only handles the license and the subscription.

Account questions.
Why do I need to sign in here if HarnessUp has no login?
The app still has no login. This page exists only for subscribers: it's where Creem confirms the subscription is yours before showing the plan, the key and the receipts.
Does unplugging erase anything on the old machine?
No. The old machine goes back to Basic FREE at the next license check and keeps measuring. Settings, SafeBox and history stay put.
I formatted the computer without unplugging. Now what?
Sign in here and unplug the old machine with the button on the active machine. Then plug the license into the formatted computer as if it were a new machine.
I lost the email with the key.
Sign in with the email link: the key shows on the license panel, with copy buttons. If the purchase email is lost too, write to help@harnessup.dev.
How do I change the card or request a receipt?
On the Creem portal, under manage subscription. Creem is the merchant of record and issues all HarnessUp receipts.
Can I use the same key on two machines?
Not at the same time: each key has one activation at a time. For several machines or people, the Team plan gives you 10 GIGA licenses in a single payment.
