The short version
This site sets one cookie, and it exists so that signing in works. There is no analytics here, no advertising pixel, and nothing following you around the internet.
That is unusual, and it is deliberate. If it changes, this page changes with it.
The cookie we set
A sign in session cookie. When you sign in to the book or the course, the site sets a signed cookie so it knows it is still you as you move between pages. Without it you would be asked to sign in on every click.
It is strictly necessary. It carries no advertising identifier and it is not shared with anyone.
To remove it, sign out or clear cookies in your browser. You will then need to sign in again.
What we do not do
No Google Analytics or any other analytics package.
No Meta, LinkedIn, Google, or other advertising pixel.
No retargeting, no conversion tracking, no cross site tracking.
No fingerprinting, no session recording, no heatmaps.
No cookies from any advertising network, because there are none on this site.
That was verified against the live build on 2 August 2026.
Third party services
Two services are involved in delivering the site and may set their own technical cookies or local storage:
Cloudflare, which hosts the site and delivers the course videos. Cloudflare may set cookies for security and performance.
A public code library service, used to load the video player on the course page.
Neither is used for advertising.
Server logs
The hosting provider keeps standard web server logs, including IP addresses and page requests. They are used for security and troubleshooting and are kept for a short period. This happens on every website; it is not tracking in the marketing sense.
Your browser
Every major browser lets you block or delete cookies. If you block the sign in cookie, the book and the course will not work, but the rest of the site will be fine.
If this changes
The moment analytics or advertising tracking is added to this site, this page is rewritten and a consent banner is very likely to be required. That has not happened yet.
