Privacy Policy

Last updated: January 1, 2025

The Short Version

We collect no personal information. Every calculation you perform runs entirely in your browser — no data is ever sent to our servers. We don't use cookies, we don't track you, and we don't sell anything.

1. Information We Collect

We collect no personally identifiable information. Specifically:

  • We do not require you to create an account or sign up.
  • We do not ask for your name, email, or any contact details.
  • All calculator inputs you enter stay in your browser and are never transmitted to any server.

2. Cookies & Tracking

This website does not use tracking cookies, analytics scripts, or behavioral advertising trackers. We may use a minimal session cookie required for normal browser operation (e.g., CSRF protection), but no persistent tracking cookies are set.

3. Third-Party Services

We may use the following third-party services:

  • Google AdSense — if ads are enabled, Google may use cookies to serve relevant ads. You can opt out via Google's Ad Settings.
  • Hosting provider — our hosting provider may collect standard server logs (IP address, browser type, pages visited) for security and operational purposes. These logs are not used for marketing.

4. How We Use Information

Since we collect no personal data, there is nothing to use, share, or sell. Any server logs retained by our hosting provider are used solely for security monitoring and are not shared with third parties for marketing purposes.

5. Children's Privacy

Our website is suitable for all ages. We do not knowingly collect information from children under 13. Because we collect no personal information from any user, there is no special risk to children using this site.

6. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated "Last updated" date. Continued use of the website after changes constitutes your acceptance of the revised policy.

7. Contact
