Three subscriptions: Free at $0 USD, Round at $11 USD per month, Roster at $33 USD per month, all inclusive of statutory VAT (inkl. MwSt.). Yearly billing is available on the paid plans. Subscriptions renew automatically until you cancel, and you can cancel at any time from your billing page with effect from the end of the paid period.
Each plan includes a monthly allowance of credits, used when the assistant is instructed and when a summary sheet is generated. A member filling in their measurements never costs the organiser anything. Credits are a service allowance only: they are not money, cannot be topped up, bought separately, exchanged, refunded or transferred, and unused credits do not carry into the next period. If you run out, the only route is a higher plan. Full terms in the AGB.
