Home/Refund policy

Refund policy

You can ask for a refund for any reason within 30 days of your purchase.

How to ask for a refund

Our orders are processed by Paddle.com, our reseller and Merchant of Record, so refunds are handled by Paddle. Go topaddle.net, look up your order with the email address you used, and ask for a refund. You can also reply to your receipt email. If you get stuck, email us at support@blueprintexercises.com and we will sort it out.

What happens after a refund

  • The money goes back to the payment method you used. How long that takes depends on your bank or card.
  • Your Pro access or Exam pass ends when the refund is made, and a subscription stops renewing.
  • Your account, progress and certificates stay. You can keep using the free preview.

Cancelling instead

If you only want to stop a subscription from renewing, cancel it from your account page. You keep access until the end of the period you paid for.
