Diagram generation uses credits. A generation may reserve or consume a credit before AI processing and rendering complete. If a generation fails after a credit is consumed, the system is designed to automatically refund the consumed credit when the failure is recorded.
Paid plans provide a defined credit allowance for the billing period. Unless the plan page states otherwise, paid plan credits reset each billing cycle and do not roll over. Trial or promotional credits may be limited, expire, or be changed at any time.
Payments, subscriptions, checkout, invoices, and customer portal features may be processed by Stripe. Your billing relationship may also be subject to Stripe’s terms, privacy policy, and payment network rules.
You are responsible for taxes, fees, and charges associated with your plan. Plan names, prices, credits, limits, and features may change as the service evolves. Changes will apply as allowed by law and by the billing flow presented to you.
If payment fails, a charge is reversed, a checkout appears fraudulent, or an invoice is unpaid, we may suspend, downgrade, limit, or terminate access to paid features, credits, API access, or generation capacity.
