Cookies we set. The site’s own pages do not set tracking cookies. Your tool preferences (such as the last conversion you ran) are kept in your browser’s local storage on your device and are never sent to us.

Third-party cookies. Advertising provided through Google AdSense may set cookies to serve and measure adverts. These are controlled by Google, not by us.

Managing cookies. You can block or delete cookies in your browser settings, and manage ad personalisation through Google’s ad settings. Blocking cookies will not stop the clock or converter from working, because those run locally.
