Privacy and worksheet settings

Last updated September 22, 2026.

Worksheet use

You do not need an account to use the worksheets. The practice tools do not ask for a student name or store student answers. Name and date lines in downloaded PDFs are blank spaces for offline use.

PDFs are created in your browser. When you explicitly save practice settings, those settings are stored in your browser on your device. They are not a saved student profile. Clear this site's browser data to remove them.

Interactive checks and optional research contributions

Answers in the skill checks stay in the current page and are lost when it is reloaded. Times-table maps and skill-path choices are saved locally only when you choose Save; use Clear in the tool to remove them. Downloaded results and plans are created in your browser.

An optional adult contribution checkbox, off by default, sends the fixed check or multiplication-fact identifier and correct/incorrect response counts to Google Analytics. It does not send the typed answer, name, age, birthday, or saved map. These events use the existing analytics service, which can process browser information and identifiers; they are not anonymous browsing. Public reports show only aggregated rows with at least 100 responses. They count responses rather than unique children and are not national benchmarks.

Analytics and advertising

The site loads Google Analytics, Microsoft Clarity, Vercel Analytics, and Google advertising scripts. These services may process page visits, device or browser information, identifiers, and interactions according to their settings and policies. Practice events describe actions such as preparing a PDF; they do not include names, typed answers or completed worksheets.

See Google's privacy policy, Microsoft's privacy statement, and Vercel's privacy policy for their practices and controls. Browser privacy settings or blockers may limit these services.

Correspondence

If you contact us, include only the information needed to explain the issue. Please do not send student names, sensitive information or completed student work. Email is handled by the email providers involved.
