Digital downloads & refunds

Digital delivery

Before being redirected to Stripe, buyers receive a private recovery code and must confirm that they have saved it. The code cannot unlock an unpaid order. Once the purchase is independently verified, the success page provides immediate access only to the purchased PDFs. Buyers can enter their saved code on the downloads page later, even after an access link expires. Access links expire after seven days. Each purchased book permits five download URL issuance sessions, plus two extra URL retries within ten minutes of each counted issuance. Issuing a URL may use an allowance even if the later transfer fails. If the buyer loses the code, support must verify the paid order and respond only to the original checkout email address. Controlled TEST purchases confirmed secure download issuance, but the automated delivery email queue has no confirmed provider deliveries. Customers must save the code; lost-code restoration requires verified manual support.

No voluntary refunds

All digital-book purchases are final. We do not offer voluntary refunds or exchanges for change of mind, accidental purchases, or unused downloads. This policy does not limit legally mandatory cancellation, refund, or other consumer remedies.

Missing, defective or incorrect orders

If a customer is charged twice, does not receive purchased content, receives the wrong file or encounters a defective download, the store must investigate promptly and provide the remedy required by applicable law. It must not require surrender of non-waivable consumer rights.
