Refunds

updated 22 October 2026

This page covers what you buy through shop.naisu.pro: digital products from every Naisu property (books, reports, data, planners, keys and app seats), which have nothing to post back and no return postage. It says when a payment is refunded. The terms of sale apply alongside it.

Before you download

Cancel within fourteen days of purchase by writing to support@naisu.pro from the email address you used at checkout. If the file has not been downloaded or opened, the payment is refunded in full.

After you download

Once you download or open the file, supply has begun and the right to cancel is lost; you consented to this at checkout. A refund is still made where the edition is faulty: the file will not open, is incomplete or corrupt, or is not the title and edition described. Tell us what is wrong. We first supply a repaired or replacement file; if we cannot do that within a reasonable time, the payment is refunded.

How a refund is paid

Refunds are issued by Stripe, the merchant of record, to the payment method you used, normally within five to ten working days of approval. Every request is acknowledged within five working days.

What is not refunded

A change of mind after download. A newer edition appearing: editions are immutable and the one you bought stays available to you. A file that opens and is the product described. The unused part of a subscription period you cancel: it runs to the end of the period, unless we ended it, in which case the unused part is refunded.

Printed copies

Printed copies of Naisu titles may be sold by other retailers, such as Amazon. They are never sold through shop.naisu.pro, because Stripe's payment service there covers digital products only. This page does not cover them: a printed copy is returned and refunded under the rules of the retailer you bought it from. If you bought a printed Naisu Limited title and need help, write to support@naisu.pro.
