Payments
Paid course prices and supported currencies are shown before checkout. Payments are processed by a third-party payment provider. nullble does not store complete payment card numbers.
Course access
Access is enabled after payment is successfully confirmed. A pending, failed, or disputed payment may delay or prevent access.
Refund requests
Standard refund requests must be submitted within four hours of the payment's confirmed timestamp. After this window, a purchase is not eligible under nullble's standard refund policy. This policy does not limit refund, cancellation, or withdrawal rights required by applicable law. For questions about a legal exception, contact support@nullble.com.
If you need help with a purchase, submit an eligible refund request from your Transactions page. We review requests according to the circumstances of the purchase and applicable law. If approved, the refund is sent through the payment provider; course access is revoked after the provider confirms the full refund.
Cancellations and disputes
Do not submit duplicate charges or payment disputes while a support request is being reviewed. If a charge is unauthorized, contact your payment provider immediately and notify nullble.
