Privacy Policy

This platform is designed to work without collecting unnecessary personal data. No account or sign-up is required to use any calculator.

Your theme (light/dark/system) and language/region preferences are stored only in your browser's local storage, on your device. They are never sent to a server and are not linked to your identity.

The values you enter into a calculator are used only to compute the result shown to you in your browser and are not stored or transmitted anywhere.

As the platform adds analytics or advertising in the future, this policy will be updated to accurately describe what is collected and why.
