License & activation
How HISAB activates inside Excel, and where your plan stands.
How activation works
HISAB has no license key to copy. You activate by signing in inside Excel — open the HISAB panel and sign in with the same email and password you use here. Your plan is checked with our server and works offline for up to a week between checks. To move to a new machine, just sign in there; to release a machine, sign out of HISAB on it.
