On this website

This site has no accounts, advertising trackers or newsletter form. Like any web server, it may keep basic technical logs. If you reach us through a tracked link, we count the click with its source, the date and your approximate country.

Payments

Purchases are handled by Gumroad, which processes your payment and email address under its own privacy policy. We receive your order details from Gumroad so that we can deliver the book and answer support requests. We never see your full card number.
