Information collected
The site may collect page path, referral domain, device category, response status, and a short-lived anonymous visitor identifier for aggregate traffic statistics. When a recognized search engine supplies a search term, the site stores the engine, a sanitized term, and landing page as daily aggregates. Terms containing an email address, long number, or URL are discarded. PDF and answer-sheet opens and print-button actions are counted per worksheet. Raw IP addresses and full user-agent strings are not stored in the analytics tables, and search or worksheet events are not linked to a visitor identifier.
Why it is used
Aggregate data helps us find popular worksheets, broken pages, and printing issues. Administrator login data is used only to secure the content management area.
Third-party services
Cloudflare provides hosting, security, and database services. We use Google Analytics 4 to understand how visitors use the site. Google may process the page URL, visit time, browser and device details, approximate location, IP address, and cookie identifiers. We do not send names, email addresses, or other directly identifying information to Google Analytics.
We use the Google AdSense connection code. Ads may appear depending on Google's site approval and ad settings. Google and its advertising partners may process cookies, IP addresses, device and browser information, and ad interactions to deliver and measure ads and prevent fraud. Personalization depends on region, consent, and ad settings.

You can block or clear browser cookies or install the Google Analytics opt-out browser add-on. Blocking cookies does not stop all ads or data processing. We do not load third-party analytics or advertising integration scripts on print-list or administrator pages.
Children
The public worksheet pages do not require a child to create an account or submit personal information. Adults should contact us on a child's behalf.
