Refund and cancellation policy

Last updated October 12, 2026

Free trial

Pro starts with a free trial. Cancel before it ends and you won't be charged anything. We'll email you a reminder before the trial ends.

Cancelling

You can cancel Pro at any time from your account. Cancelling stops the next renewal: you keep Pro until the end of the period you've already paid for, then your account moves to Free. Your saved assemblies and reports stay in your account.

Refunds

Payments aren't refunded automatically when you cancel, but you can ask for a refund and we'll review every request. To request one, email [email protected] within 30 days of the charge, from the email address on your account, and tell us which charge it is and why you're asking.

We usually approve requests such as:

• a renewal you meant to cancel, if you haven't used Pro features since it was charged;
• being charged twice, or charged after you cancelled;
• a problem on our side that kept you from using Pro and that we couldn't fix.

For a yearly plan we may refund the unused months rather than the full year. Approval is at our discretion, and we'll reply within 5 business days. Approved refunds go back to the original payment method, including any sales tax charged, and usually appear within 5 to 10 business days depending on your bank.

Simulation runs

Full assembly simulation runs are included in Pro and aren't charged separately. If a run fails or stops early, run it again or contact us and we'll look into it.

Before disputing a charge

If something looks wrong on your statement, please contact us first at [email protected]; we can usually sort it out faster than a card dispute.
