5. Delivery of rewards
Early access is provided by email to the address given at payment, upon the release of each version concerned. The first two years of licence included in the Founder (1 seat) and Founding engineering firm (10 seats) tiers start on the release of version 1.0. The founder rate (−30% on renewal of the annual licence) applies as long as the licence is renewed without interruption. It is calculated on the public price in force and applies to the edition held as well as to any edition of ARCYNDRA CAD offered later (for example a 3D edition), up to the number of seats included in the tier (1 seat for the Founder tier, 10 seats for the Founding engineering firm tier).
6. Right of withdrawal and refund
The rewards are digital content and services supplied remotely. At payment, you expressly request that access be opened immediately and acknowledge that you lose your statutory right of withdrawal once that access is opened (Article VI.53, 13° of the Code of Economic Law).
ARCYNDRA CAD nevertheless grants you a voluntary full refund within 14 days of payment, with no reason required: simply request it by email. The refund is made to the payment method used, and the corresponding rewards end.
If version 1.0 of ARCYNDRA CAD is not available by 31 December 2028, the Founder and Founding engineering firm tiers may be refunded on simple request, up to the share corresponding to the licence not supplied.
