Membership and Refunds

Updated 15 October 2026

Using the book is no longer charged

Once you have registered and verified an account, you may use the book without payment. Membership is no longer sold, and pages are no longer counted. What follows covers payments already made.

Plans

Membership that was already bought was a monthly or yearly subscription. The plans and prices were whatever the payment page showed at the time.

Payment methods

Checkout is hosted by Stripe Hosted Checkout. Whether cards, Apple Pay and other methods appear depends on your device, region, currency and the methods enabled on the Stripe account at the time.

Crediting

Membership is opened and renewed on the strength of Stripe’s signed notices. The same payment event never grants a period twice. If the page has not shown your membership after checkout, go back to the account page and refresh; do not pay again.

Refund principles

A membership already opened or renewed is in principle not refundable. Exceptions are duplicate charges, clear system errors, what applicable law requires, and verified unauthorised payments.

Cancelling

You can cancel on the account page under “Manage membership”. It is not renewed afterwards. Using the book is not charged.

What to send when you ask

To ask for a refund or help, write to (contact email to be added) with your account email, the payment date, the amount, the Stripe payment receipt and the reason. Do not send full card numbers or codes.
