Privacy Policy

This Privacy Policy explains how Prime Calculator handles information when you visit our website. We are committed to a "private-by-design" approach where your data stays on your own device.

1. No Personal Data Collection

We do not collect, store, or see any personal information. There are no sign-up forms, no contact forms that transmit data to a server, and no databases where your information is stored.

2. Local Storage & Calculation History

The Scientific Calculator features a "History" tool that saves your recent calculations. This data is stored exclusively in your browser's localStorage.

Unlike a database, this information never leaves your computer. It is not transmitted to us or any third party. You can clear this history at any time using the "Clear" button in the history panel or by clearing your browser data.

3. No Tracking or Cookies

Prime Calculator does not use cookies, Google Analytics, or any other third-party tracking scripts. Your mathematical work and browsing patterns are not recorded or analyzed by us.

4. Third-Party Links

Our site may contain links to external websites (such as browser extension stores). Once you leave our site, we are not responsible for the privacy practices of those other websites.

5. Changes to This Policy

We may update this Privacy Policy if we add new features. Any changes will be posted on this page with an updated "Last Updated" date.
