What you buy: prepaid generation credits for Mina’s Chamber (Chamber Vision Door C), not a donation, investment, or equity.
When: credits are ledgered on successful processor payment. Generation unlocks when Door C testing opens (date stated on the Founding page / purchase receipt).
Refund: if we fail to enable generation by the stated open date, or the processor cannot fulfill, email support@chambervision.online with your purchase id for a full refund of unused prepaid credits.
Chargebacks: contact support first; we honor the refund path above for delivery failure.
Not Stripe: Door C uses an adult-processor rail (Segpay-class) only.
