The short version

The calculators on this site run entirely in your browser. The numbers you type into a calculator are never sent to us, stored on a server, or shared with anyone, they exist only on your own device while you're using the page. We don't require an account, a login, or an email address to use any tool here.

What we do collect

Like most websites, we use basic analytics to understand which pages get used and how the site performs, this typically includes things like which pages were visited, roughly how long someone stayed, and general location and device information at a country or city level. This helps us understand what's useful and what to build next, it doesn't identify you personally.

Advertising and cookies

This site is supported by advertising, including through Google AdSense. Google and its advertising partners may use cookies to show ads based on your visits to this and other sites. You can review or opt out of personalized advertising through Google's Ads Settings, and general information about how Google uses data from partner sites is available through Google's own policies.

Most browsers let you block or delete cookies through their settings if you'd prefer not to accept them, though some site features may not work as well without them.

Third-party links

Some pages link to outside resources or, where relevant, to Google's own tools and settings pages. We aren't responsible for the privacy practices of sites we don't operate, so it's worth checking their own policies before sharing information with them.

Children's privacy

This site is intended for business owners, managers, and freelancers, and isn't directed at children. We don't knowingly collect information from children.

Changes to this policy

We may update this policy as the site changes. Significant changes will be reflected in the date at the top of this page.
