Essential storage

The site may store a theme preference (light/dark) in local storage or a small cookie so the interface stays consistent. This is not used for advertising.

Analytics and ads

On the production domain, third-party scripts such as advertising or analytics may set cookies according to their own policies. Those providers process data under their terms.

Managing preferences

You can clear cookies and site data in your browser settings. Blocking all cookies may affect theme persistence but calculators still work for core math shown in HTML tables.
