The site

Privacy

This site is published by Ralph Ellis, through Edfu Books, in Cheshire, England. It does not sell addresses, and it does not run advertising.

Contact

The contact form sends your name, email address, and message to Ralph so he can reply. Delivery is handled by FormSubmit. The message is kept so he can answer it, and for no other purpose.

The mailing list

If you sign up, only the email address is sent to Ralph. He writes when a new lecture or a new edition is published. There is no weekly mailing. To come off the list, write through the contact form.

Page counts

The site keeps a private tally of which pages are opened and which links are used, such as a book, a lecture, YouTube, or Amazon. The tally is a total. It does not store your name or email address. A note in the browser, for that visit only, stops the same page being counted twice.

On this device

Light or dark appearance is saved in the browser and is not sent anywhere.

Other sites

Lectures play from YouTube. A book link opens Amazon. Patreon, X, and Facebook are their own sites, with their own rules.
