How local worksheets, checklists, hosting and external links work.

Browser tools and storage

Search, category filters, checklists and worksheets run in your browser. Worksheet edits and checkbox selections are stored locally on this device when the browser permits storage. They are not sent to this website and do not sync to another device. Use the tool’s clear button or clear this website’s browser data to remove saved entries. CSV exports are created on your device.

Hosting and downloads

The web server may record request times, IP addresses, requested paths and browser information for operational purposes. Photos, fonts, scripts, styles and downloadable files are served locally; no external font service is requested. This edition has no account, payment, newsletter or comment form.

Advertising and analytics

Google AdSense advertising code is included on this website. Ads can be displayed only after Google approves the site and subject to the account's advertising settings.

Third-party vendors, including Google, may use cookies to serve ads based on visits to this website and other websites. Google's advertising cookies can enable Google and its partners to serve personalized ads where permitted.

You can manage personalized advertising through Google Ads Settings. Other advertising vendors may offer their own controls; additional opt-out information is available at YourAdChoices.

See how Google uses information from sites that use its services. No separate audience analytics service has been added. Where consent controls are required, ad serving depends on the applicable consent settings.

External links

Reference and photography links lead to independently operated websites with their own privacy practices. Avoid putting passwords, identification numbers or payment details into local worksheets or shared exports. Notice dated 18 October 2026.

Article popularity

Articles are ordered by aggregate reading counts. An anonymous random visit token is kept in this browser session so repeatedly opening the same article within thirty minutes does not repeatedly increase its count. The counting service stores a keyed hash of that token temporarily and aggregate article totals. It does not create an account or store the token with notebook entries. The token ends with the browser session; temporary deduplication records are removed after a day. Operational hosting logs are described elsewhere in this notice.
