| Delivery timing (引渡時期) | Credit is delivered electronically to the purchaser's Ulearn account immediately after Stripe confirms a successful payment (typically within seconds). No physical shipment. |

Defective service / failed transactions: If you are charged but credit is not applied, or if the service malfunctions and credit is consumed without delivering the expected result, contact academysiegel@gmail.com. We will either apply the missing credit or issue a full refund to the original payment method via Stripe.
Customer-initiated returns: Purchased credit that has not been consumed may be refunded within 14 days of purchase by emailing academysiegel@gmail.com from the registered account email. Refunds are issued to the original payment method via Stripe. Credit that has already been consumed for AI calls is non-refundable because the underlying third-party API costs have been incurred. Account deletion: Users may delete their account at any time from the Account tab. This does not automatically trigger a refund of remaining credit; request refunds by email before deleting. |
