Calculator and browser storage

The calculator processes its inputs in your browser; the site code does not submit them to a server or save them. The site has no newsletter signup or contact form. Hosting providers may process ordinary request information such as IP addresses when delivering pages.

A previous banner may have stored a choice and an approximate region in your browser. That stored choice does not control Google advertising. You can clear old site data in your browser settings.

Advertising and choices

When advertising is enabled, the site loads Google AdSense. Google and its partners may use cookies or similar technologies and information from visits to this and other sites to serve and measure ads, including personalized ads. See how Google uses information for advertising.

You can manage Google's ad personalization in My Ad Center, and manage cookies through your browser. Turning off personalized ads does not necessarily stop all ads. External sites have their own privacy practices.
