Refund & Billing Policy

Compute credits: no results, no charge

You are only charged for a simulation run that actually completes and returns results. If a run fails to build or fails during simulation, or if you cancel a run that is still queued or running, the compute credit already debited for that run is automatically credited back to your balance in full. No request is needed — this happens the moment the run reaches its failed or cancelled state.

A retried run is a new, separately priced and separately charged run — the credit-back does not carry forward as a free retry.

Credit packs

Credit packs are a one-off purchase (available in $10 and $25 packs) that top up your compute balance. The full pack amount is credited to your balance as soon as the Stripe checkout completes.

• Pack credits do not expire.
• If a credit-pack payment is refunded or successfully disputed through Stripe, the corresponding credit is automatically removed from your balance.

Private-model subscription

The private-model subscription ($100/month USD) is billed in advance and keeps a project visible only to the people you invite. To cancel, contact us — we process the cancellation on our end.

Cancelling stops future billing. It never automatically makes a private project public again — a project you have made private stays private, and it is entirely your decision whether to change its visibility afterwards.

Subscription payments are not currently eligible for a partial-period refund.

If a renewal payment fails

Access is not withdrawn immediately. You will see a renewal reminder while our payment provider automatically retries the charge on its usual schedule. Private-model access is only withdrawn once that process concludes without a successful payment.
