Privacy Policy

This Privacy Policy explains how BMI Calculator (the "Site") handles information when you use it. This is a starter policy intended for a simple, static site — replace the placeholders below with your own details before publishing.

Calculations happen in your browser

The BMI calculator on this Site runs entirely client-side, using JavaScript in your browser. The age, gender, height, and weight values you enter are used only to compute your result on your device and are not transmitted to any server operated by this Site.

Local storage

The Site may use your browser's local storage to remember your dark mode preference and, optionally, a short history of recent BMI results, entirely on your own device. This information stays in your browser and is not sent anywhere. You can clear your saved results at any time using the "Clear saved results" option, or by clearing your browser's site data.

Information we do not collect

This Site does not require account creation, does not ask for your name or email to use the calculator, and does not knowingly collect personal health information on a server.

Cookies and analytics

At the time of writing, this Site does not use tracking cookies or analytics services. If analytics or advertising services are added in the future, this policy will be updated to describe what data those third-party services collect and how you can control it. [Update this section if/when you add Google Analytics, an ad network, or similar services.]

Advertising

This Site is designed to support advertising in the future to help cover hosting and development costs. When an advertising provider is added, this section will be updated to name the provider(s) used and describe any cookies or tracking they employ, along with your options to opt out where applicable.

Children's privacy

This Site does not knowingly collect personal information from children. The calculator includes guidance for users under 18 explaining that adult BMI categories don't directly apply to them.

Changes to this policy

This policy may be updated from time to time, particularly as analytics or advertising services are added. Continued use of the Site after changes are posted constitutes acceptance of the revised policy.
