Privacy Policy

Last updated: 3 October 2026. This page explains what this site collects and what third parties operating on it may collect.

What we collect directly

Nothing that identifies you. There are no accounts, no sign-up, no newsletter and no contact form. Worksheet settings — the problem count you last chose — are stored in your own browser and never sent to us.

Analytics

We may use a privacy-focused analytics service to count page views in aggregate. Where used, it records the page address, approximate country and referring site. It does not set advertising cookies and does not build a profile across sites.

Advertising

This site is supported by advertising. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites.

Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and other sites on the internet. You may opt out of personalised advertising by visiting Google Ads Settings, or opt out of third-party vendors' use of cookies for personalised advertising at aboutads.info.

Third-party vendors and ad networks other than Google may also serve ads on this site. You can review their privacy policies and opt-out options through the links above.

Children

These worksheets are intended for use by parents and teachers with children. The site is not directed at children as users, does not knowingly collect information from children, and has no feature that would allow a child to submit information to us.

Your choices

You can block or delete cookies in your browser settings at any time. The worksheets and the generator work with cookies and JavaScript storage fully disabled.

Changes

If this policy changes, the date at the top of this page changes with it.
