This is a one-page site that sells one book. It is kept deliberately small, and so is this.
Nothing. There are no accounts, no forms, no newsletter box, no comments and no chat widget. There are no analytics and no advertising or tracking pixels. No cookies are set by this site.
The site is served by Cloudflare Pages. Like any web host, Cloudflare records standard server request information — things like the IP address a request came from, the time, and which page was asked for — in order to serve the page and protect it from abuse. That data is held by Cloudflare under its own privacy terms, not by me, and I do not query it or build profiles from it.
The buy button hands you over to Gumroad, which is a separate company and a separate site. Everything about the purchase happens there: your email address, your payment details, the receipt and the download link. This site never sees your card details and neither do I.
Gumroad tells me the email address of people who have bought the book, so that a download can be resent if something goes wrong. That is the only personal information I hold about a customer.
How Gumroad handles your data is covered by Gumroad's own privacy policy, which you should read before you buy. Requests to see, correct or delete what Gumroad holds are best made to Gumroad directly.
I do not run a mailing list and I will not add you to one. If you reply to your Gumroad receipt, I will read it and answer it, and I keep that correspondence only as long as it takes to sort the problem out.
This book and this site are meant for adults and are not directed at children.
If this changes — if analytics are ever added, for instance — the date at the top of this page changes with it.
