Usage analytics, the details Stripe needs to process an order, and what you send us. Nothing is sold.

Pages you view, how far you scroll, links you follow out, files you open, the kind of site that referred you (search, social, an AI assistant), and checkout steps. Google Analytics sets first-party cookies to recognise a returning browser. No names, emails, or payment details are sent to it.
Checkout runs on Stripe. Stripe collects your card details; this site never sees or stores them. We receive your name, email, billing and (for hardcovers) shipping address, and what you ordered, to fulfil and support your order. Stripe’s privacy policy applies to the data it processes.
If you write to us, we keep the correspondence to answer you and to honour any request it contains.
The site is served by Vercel, which keeps standard request logs for security and reliability.
