Privacy Policy

Last updated: July 2026

At Circle Area Calculator, we are committed to keeping your browsing experience safe, private, and clear.

1. Zero Data Collection

We do not collect, store, or transmit any personal data. All circle calculations (radius, diameter, circumference, and area) are performed locally inside your browser using JavaScript. No calculation metrics or typed numbers are ever sent to our servers.

2. Cookies and Tracking

We do not use tracking pixels, advertisements, or marketing cookies. We do not integrate with third-party tracking services. Your actions on this site remain entirely private to you.

3. Local Storage

Our application may use temporary session state variables or URL search parameters to remember your last calculation input (for instance, to allow you to copy a shareable link). This information is stored solely on your device and is not synchronized to any database.

4. Contact Us

If you have questions about our zero-data privacy practices, please contact us via our contact form.
