Privacy Policy

The short version

Our calculators run entirely in your browser. The numbers you type into a calculator are not sent to our servers and are not stored by us. We collect only limited, standard information needed to run and improve the website.

Information we do not collect

• We do not require an account or sign-up.
• We do not save the values you enter into calculators.
• We do not sell personal information.

Information that may be collected automatically

Like most websites, our hosting and analytics may automatically log standard technical data such as your IP address, browser type, device, referring page and the pages you visit. This is used in aggregate to understand usage and keep the site secure and fast.

Cookies and analytics

We may use privacy-respecting analytics and essential cookies to measure traffic and improve our tools. If we display advertising in future (for example, Google AdSense), advertising partners may use cookies to serve and measure ads in line with their own policies. Where required, we will request your consent and provide controls. You can also manage or block cookies in your browser settings.

Third-party services

We rely on third parties for hosting, content delivery and analytics. These providers process data on our behalf and have their own privacy practices. External links (such as government reference pages) are governed by the privacy policies of those sites.

Your rights

Depending on where you live (for example, under the GDPR or CCPA), you may have rights to access, correct or delete personal data we hold about you, or to object to certain processing. To make a request, contact us at [email protected].

Children

This website is not directed at children and we do not knowingly collect personal information from children.

Changes to this policy

We may update this policy from time to time. The “last updated” date above reflects the latest revision.
