Privacy

We collect an email address only when you ask for the free download or buy a PDF. It is used to send you what you asked for and, at most, occasional notices of new editions; every message includes an unsubscribe link. We do not sell or share addresses.

Purchases are processed by Creem, our merchant of record, under its own privacy policy; we never see your card details. Amazon purchases are governed by Amazon's policies.

The site uses no advertising trackers. Cloudflare, which hosts the site, records standard server logs for security.
