When you buy a book, Polar (our merchant of record) processes your payment and your email address so it can send you the download link and a receipt. We do not see or store your card details.

We use your email address only to deliver your purchase and to answer you when you write to us. We do not sell or share it.

This site does not use advertising trackers. To ask about or delete your information, email the address on your purchase receipt.
