Short, because there isn't much.

Email. If you request the gift or the newsletter, we store your email address and where the sign-up came from (for example a QR code in a book). Double opt-in. Used only to send the gift and occasional news about new books. Every email has an unsubscribe link; unsubscribing deletes you from the list.

Analytics. We use cookieless, privacy-friendly analytics (self-hosted) to count page views and which link brought you here. No advertising trackers, no cross-site profiles.

Purchases. Paperbacks are sold by Amazon under Amazon's terms. Printable PDFs are sold through a payment provider that handles checkout and VAT; we receive your email to deliver the file.

Children. The site is for parents and adult colorists. We do not knowingly collect data from children.
