PAYMENTS / 28 OCTOBER 2026

Payments and refunds

Paid membership is a single payment for 12 calendar months. There is no automatic renewal or recurring charge to cancel. Dodo Payments sells the membership as merchant of record and issues the receipt. Prices include applicable taxes, which Dodo Payments collects and remits as merchant of record.

Immediate access and final sale

Membership opens as soon as payment is confirmed. When you pay, you ask for that immediate access and acknowledge that, where the law allows, this ends any statutory right to withdraw from or cancel the purchase. Sales are therefore final: we do not refund a change of mind, unused time or a membership you no longer need, except where the law of your country requires a refund or Dodo Payments grants one under its buyer terms. The open lessons and free sample problems let you judge the material before paying. Your mandatory consumer rights are unaffected.

Billing problems

Contact [email protected] from your account email, with your order reference, about a duplicate charge, an unsuccessful purchase that was charged, or paid access we have not supplied. We verify the order and respond with its status, and put a confirmed fault right, normally by restoring or extending access or by asking Dodo Payments to refund the charge. Approved refunds are issued by Dodo Payments through the original payment method; bank processing times vary.

Refunds and disputes end access

A refunded membership, or one whose payment is reversed or disputed with your bank, no longer provides paid access. Please contact us before opening a dispute so we can help first. We never ask for your card number, CVV, password or Google security code.

Payment pending?

Check your dashboard before attempting another payment. If you were charged but access is missing, send support the provider reference. Do not pay again just because a browser window closed.
