The Cipher Librarian / Privacy
A simple site.
A clear approach.
This author website provides book information and links to Paul Clark’s projects.
What this site does
The site does not include an email sign-up form, advertising trackers, or third-party analytics scripts. Fonts and images are served with the site. Site hosting may process standard request information, such as an IP address, for delivery and security.
Contacting Paul
Email links open your email application. Information you choose to send is handled through email. Please do not include confidential information in an initial inquiry.
Other websites
Links to Cipher Museum, Crypto Lab, and other resources take you to separate websites, which may have their own privacy practices.
For questions, email paul@systemslibrarian.dev.
