Sponsors
The work is free to read and asks for no email. Sponsorship is how that stays true — and it is deliberately kept at arm's length from everything you learn.
What a sponsor buys
A slot and a flight window. Nothing else. A sponsor's name may appear in a marked place — this page, or a sidebar — and never inside a lesson, a quiz, an exam, or in how any of it is scored.
What a sponsor cannot buy
- No affiliate links in any lesson. The content and the money are separated in code, not just in policy: the sponsorship module is forbidden from even importing the lesson code, and the build fails if that ever changes.
- No influence on rubric or ranking. Exams and grading are published and reproducible; a sponsor cannot move a score.
- No third-party analytics, no tracking. A sponsor learns nothing about who read what.
Every placement carries a plain disclosure label, always visible, so you always know what is sponsored and what is not.
