The short version

This site does not use advertising trackers. We collect only what is needed to sell and deliver the PDF.

When you buy

Stripe collects your payment details, name, and email address. We receive your email address, name, and country so we can confirm the order and help you if something goes wrong. We never see your full card number.

When you visit

Our hosting provider, Cloudflare, may keep basic technical logs such as your IP address and the pages you request, to keep the site running and secure.

What we do with it

We use your information to deliver your purchase and answer your questions. We do not sell it. We may keep order records as long as the law requires.

Your choices

To ask about the information we hold or to have it removed where the law allows, email kepleroates@gmail.com.
