Privacy Policy
Last updated: June 2026
Calcool ("we", "us") respects your privacy. This page explains what data is and isn't collected when you use the calculators at calcool.us.
Your calculator inputs stay on your device
Every calculator on Calcool runs entirely in your web browser using client-side JavaScript. The numbers you type — salaries, loan amounts, cash flows, anything — are processed locally and are never uploaded to or stored on our servers. When you close or reload the page, those inputs are gone.
Cookies and analytics
We may use privacy-respecting analytics to understand which calculators are used and how pages perform, so we can improve them. Any analytics cookies are used only in aggregate and are not tied to your identity. You can block cookies in your browser settings without losing access to the calculators.
Advertising
Calcool is supported by advertising, which keeps the tools free. Third-party ad partners may use cookies or similar technologies to serve and measure ads. These partners operate under their own privacy policies. Where required, a consent banner lets you manage your choices, and you can opt out of personalized advertising through your browser or the partner's own controls.
What we don't do
- We don't sell your personal information.
- We don't require an account or ask you to log in to use any calculator.
- We don't store the financial or personal figures you enter into the tools.
Children's privacy
Calcool is a general-audience reference site and is not directed at children under 13. We do not knowingly collect personal information from children.
Changes to this policy
We may update this policy as the site evolves. Material changes will be reflected by updating the date at the top of this page.
