Refund policy

Last updated: September 17, 2026

This policy applies to paid subscriptions to TryMermaid from Try Mermaid LLC ("we", "us"). It forms part of our terms of service.

1. Try it free first

TryMermaid has a Free plan that includes the full web app and up to 50 saved diagrams, so you can make sure it works for you before you pay. Compare plans on the pricing page.

2. No refunds

All payments are final and non-refundable. We don't offer refunds or credits for partial billing periods, unused time, downgrades, or periods where you didn't use the service. This applies to monthly and any other billing periods we offer.

3. Cancelling your subscription

You can cancel at any time. Cancelling stops future charges; you keep Pro features until the end of the billing period you have already paid for. Your account then moves to the Free plan. No diagrams are deleted, but you'll need to be under 50 saved diagrams to save new ones.

4. Billing mistakes

If you were charged twice for the same period, or charged after you cancelled, email us within 30 days of the charge and we will correct the error.

5. Your legal rights

Nothing in this policy limits rights you have under consumer protection laws that can't be waived. Where the law where you live gives you a right to a refund, we will honor it.

6. Chargebacks

If you have a problem with a charge, please contact us first so we can help. We may suspend Pro access on accounts with an open chargeback while it is resolved.

7. Changes to this policy

We may update this policy from time to time. The date at the top of the page shows when it last changed. Changes don't apply to payments made before they take effect.
