Privacy and worksheet settings

Last updated September 17, 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.

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.
