Your numbers are yours. Everything you type into a calculator is processed entirely in your browser.

What we collect

Calculator inputs: processed locally in your browser and not sent to or stored on our servers.
Anonymous analytics: aggregate page-view data to understand which tools are useful. No personally identifying information is required to use the site.

We may use privacy-friendly analytics and, where shown, clearly-labelled affiliate links. Third-party partners have their own privacy policies.

We may update this policy as the site evolves. Material changes will be reflected on this page.
