Privacy policy

We aim to collect as little information as possible. This policy describes the current site foundation.

Effective date: November 7, 2026

Information stored on your device

Practice progress may be saved in your browser’s local storage so you can resume without registering. That information stays in the browser on your device unless you clear site data. The current site does not require an account.

Analytics and advertising

Analytics and Google AdSense are not currently connected in this project. If they are added, this policy and the site’s consent controls must be updated first. Advertising and analytics providers may use cookies or similar technologies under their own policies.

Children

This site is a general educational resource and is not designed to collect personal information from children. Do not submit sensitive personal information through this site.

Your privacy choices

You can clear browser site data to remove saved practice progress. When analytics or advertising are enabled, privacy choices and consent options will be provided as required for applicable jurisdictions.

Policy changes

This policy must be reviewed when site features, service providers, or legal requirements change.
