Privacy
Short version: this site has no accounts, no sign-up forms, no ads and no tracking cookies. We do not collect personal information from visitors.
Visit statistics
We use Cloudflare Web Analytics to count visits and see which pages are popular, so we can make better books. It does not use cookies, does not track you across other websites and does not identify who you are. We only see totals, such as the number of visits per page and the country they came from.
Our website host may also keep standard technical logs to keep the site running and secure.
Children
This site is for parents, teachers and other grown-ups. We do not knowingly collect personal information from children under 13. If you believe a child has given us their email, write to us and we will delete it.
Your rights
You can ask us to show, correct or delete your information at any time.
