Cookie Policy

Last updated: 5 August 2026

What cookies are

Cookies are small files a site stores in your browser. Related technologies such as localStorage work the same way but are never sent to a server automatically.

Categories we use

• Strictly necessary — security and load balancing. These are always on and set no advertising identifiers.
• Preferences — your cookie choice and game settings, stored in localStorage under keys beginning duckmath.
• Analytics — aggregate page view measurement. Only loaded after you accept.
• Advertising — Google AdSense and its certified partners may set cookies to measure and personalise ads. Only loaded after you accept.

Changing your choice

Clear this site's data in your browser settings and the consent banner will reappear on your next visit. You can also block third-party cookies entirely; the games will still work.
