Privacy Policy

The numbers you enter into any calculator are processed entirely in your browser. They are never sent to, stored on, or logged by our servers.

We use Google Analytics to understand aggregate traffic, such as which pages are visited and how visitors find the site. Analytics cookies are only set if you choose Accept in the cookie banner; you can change your choice at any time with the Cookie settings link at the bottom of every page. IP addresses are anonymised, and we never use analytics for advertising or to identify you.

To keep the calculators free, some pages show ads served by Google AdSense and, where noted, other advertising partners. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. Google’s use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the Internet.

You can opt out of personalised advertising in Google’s Ads Settings, and learn more in how Google uses information from sites that use its services. You can also opt out of some third-party vendors’ use of cookies for personalised advertising at aboutads.info. Visitors in the EEA, UK and Switzerland are asked for consent before personalised ads are shown. Ads are never shown in embedded calculators.

Questions about this policy can be sent through the details provided on our About page.
