Refund Policy
Effective September 4, 2026
For a duplicate charge, an unauthorised payment, a file that will not open, a download that never arrives, or a product that does not match its description, email [email protected] with your order number. We will review a refund or replacement and reply within two business days. Tell us within 14 days of the charge and, where one of those cases applies, we refund or replace — you do not have to argue for it.
Because downloadable files can be kept once access begins, change-of-mind refunds may be restricted after delivery. Nothing on this page limits the consumer rights you have by law in your country.
1. What we cover, and what a downloaded file changes
Our books are downloadable PDF and EPUB files, not physical goods. Because a file can be retained after it is delivered, we do not offer exchanges. Once download or access begins, we do not offer change-of-mind refunds where the restriction was clearly presented before purchase and the required express consent was obtained. This does not limit consumer rights that cannot legally be excluded.
2. Before supply begins
If you ordered the wrong product and have not accessed or downloaded it, contact us promptly with your order number and purchase email. We will assess cancellation under applicable law and the payment provider’s rules.
3. Refund-eligible cases
We review duplicate orders, unauthorised charges, a materially incorrect product description, non-delivery, and a technical defect that prevents reasonable use and cannot be corrected by replacement files or support. A download or access record does not remove rights that cannot legally be excluded.
4. How to request help, and by when
Include the order number, purchase email and a clear description of the issue. We may request reasonable evidence needed to reproduce a technical defect. For the refund-eligible cases in section 3, write to us within 14 days of the charge and we will refund or replace; after 14 days we still review the request, but we may not be able to reverse the payment through the platform that processed it. This page does not replace any statutory notice period, and a longer period given to you by law still applies.
5. Processing and records
Where a remedy is due, it is returned to the original payment method through the platform that processed the order — Lemon Squeezy or Gumroad for English editions, Latpeed for Korean editions. Lemon Squeezy and Gumroad act as Merchant of Record and may also make determinations under their own payment and chargeback policies. Korean-language purchases through Latpeed follow Latpeed’s published cancellation rules. We use available order, supply-start and download/access records to investigate a request.
6. Contact
Send order and file-access questions to [email protected]. Our standard response target is two business days.
