Privacy Policy

The short version: we only collect what we need to deliver your books.

Last updated: October 2026

1. What we collect

When you buy a book, we collect your name and email address — and nothing more. That’s all we need to send your download link and receipt.

2. How we use it

We use your email to deliver your purchases and, only if you opt in, to send occasional notes. We don’t spam.

3. What we never do

We never sell, rent, or share your personal information with third parties. Period.

4. Payments

Payments are handled by our secure payment provider. We never see or store your full card number.

5. Cookies

We use a small number of cookies to keep the site working — like remembering what’s in your cart. You can disable cookies in your browser, though some features may not work.

6. How long we keep data

We keep order records for as long as needed to serve you and meet legal requirements. You can ask us to delete your data anytime.

7. Contact
