Cancellation and refunds

Last updated 16 October 2026

Cancelling Pro

Pro is a monthly or yearly subscription that renews automatically. You can cancel at any time, from the payment confirmation email or by writing to the address on our contact page. After you cancel, you won't be charged again and you keep Pro until the end of the period you've paid for.

Pro payments are not refundable

Pro gives immediate access to every problem, so monthly and yearly payments aren't refunded, in full or in part, once the period has started. Ten problems are free for every account, so you can try the platform before you pay. Cancelling stops the next payment; you keep Pro until the end of the period you've paid for.

AI review credits

  • Credit packs are not refundable.
  • If an AI review can't be completed, its credit is returned to your balance automatically.

Charged by mistake

Billing mistakes are always refunded: if you were charged twice, charged after cancelling, or charged an amount different from the price shown at checkout, we refund the extra amount in full.

How to ask, and how long it takes

Write to the address on our contact page from the email address you sign in with, and include the payment or order id from your receipt. We reply within 3 working days. Approved refunds go back to the original payment method, which usually takes 5–7 working days to show up, depending on your bank.
