Privacy and browser storage

How local notes, checklists, hosting requests and external links work.

Reading and local tools

You can read the guides without an account. Search and category filters run in your browser. Optional checklists and notebook entries use this site’s local browser storage. They are not uploaded to a processing server or synchronized to an account. Clear controls remove saved entries; browser settings can remove all site storage.

Downloads

Notebook CSV files are created on your device after you choose to export. Printing uses your browser. Save a copy of notes you want to keep before clearing site data.

Hosting requests

Pages, styles, scripts and original SVG diagrams load from this host. Operational server logs may contain IP addresses, request times, requested paths, browser information and errors. No fixed retention period is promised here. This website has no account, newsletter, payment or comment form.

Advertising and analytics

An AdSense identification meta tag and ads.txt authorization identify a potential publisher. No advertising request script, analytics tracker or externally hosted font is enabled. Disclosures and applicable consent controls need to reflect any later advertising activation.

Contact and external references

Contact links open the main publisher site, where its contact form and privacy notice apply. External source sites operate independently and have their own privacy practices. Do not put identification numbers, bank information, passwords or sensitive health records into notebook fields or shared exports.
