Privacy Policy
This policy describes what the site collects, what it does not, and how a reader can contact the maintainer about either. The short version: the site is a static notebook that collects almost nothing.
What is collected
The site is static. It stores no accounts, no inputs and no personal data. Standard server logs may record request metadata such as IP address and user agent, retained by the hosting provider for security purposes under the provider's own retention policy.
Aggregate analytics are used to count page views. The analytics script does not build advertising profiles, and the notebook does not run advertising networks beyond its own sponsor slot.
Cookies and third parties
The site sets no tracking cookies of its own. The analytics provider may set functional cookies for aggregate counting; the sponsor slot is managed by a first-party script and does not share data with third-party advertisers.
No commerce occurs on the site, so no payment data exists anywhere in its scope. External links, where present, are public references and are not affiliate links.
Reader rights and contact
Readers who wish to ask about the minimal data described above can reach the maintainer through the contact route on the about page. Requests to review or remove any stored request metadata should be directed to the hosting provider, which controls those logs.
This policy is dated to the last substantive revision, like every page in the notebook, and superseded versions are retained rather than deleted.
