Book updates and privacy

Email sign-ups are optional and handled by Gumroad: you enter your email on Gumroad's sign-up page, then confirm the subscription using the link Gumroad emails to you, under Gumroad's terms and privacy policy. We use the list to send practical AI tips, book updates and offers. You can unsubscribe through any of those emails, or by writing to imperiumpost33@gmail.com. We do not sell the sign-up list.

Purchases take place on the retailer’s website under that retailer’s terms. When enabled, Cloudflare Web Analytics measures page visits and Umami Cloud measures page views and clicks on buy and sign-up links without tracking cookies. We send no email addresses or form contents to analytics; providers may process browser and session metadata as described in their policies. Hosting and form providers may maintain their own operational logs.
