Your calculator numbers

All calculations run in your own browser. The numbers you type into any calculator are never sent to us, never stored, and never shared. There are no accounts and no sign-ups on this site.

Analytics

We use aggregate analytics (such as Google Analytics) to understand which calculators people use and whether pages work correctly. This tells us things like page views and approximate region — never the numbers you entered.

Advertising

This site is supported by advertising (such as Google AdSense). Ad providers may use cookies to serve and measure ads, including personalized ads where you have consented. You can control cookies in your browser settings, and personalized advertising through your ad-settings page with the provider.

Contact

Questions about this policy can be sent via the contact address listed on the About page once the site launches.
