Privacy Policy.
Short, because we collect almost nothing. Last revised 1 August 2026.
| What we collect | Two things. An email address, when you give one to the Registry or to unlock a solutions archive. And anonymous, aggregate page counts — no cookies set by us, no cross-site tracking, no advertising identifiers. |
|---|---|
| Why we collect it | To send you a note when a new volume is published, and to know roughly which pages people read. That is the whole of it. |
| Who else sees it | Our mailing provider, which stores the list, and our hosting provider, which serves the pages. We do not sell, rent, trade or share your address with anyone else, ever. |
| Downloads | Solutions PDFs are gated behind an email address. Once you have unlocked a key, the link keeps working. If you would rather not give an address, write to us and we will send the file. |
| Amazon | Books are sold through Amazon KDP. When you follow a link to a product page you are on Amazon’s site and subject to Amazon’s policies, not ours. |
| Your rights | Write to us and we will tell you what we hold, correct it, or delete it. No form, no verification hoops — one email. |
