1. Information We Collect
Because we do not use databases or user logins, we collect very little information:
- Calculation Data: All matrix inputs and calculations are processed using vanilla JavaScript running directly on your device. We do not store or transmit your matrix values to any external server.
- Log Files: Like most websites, we collect standard server log data (such as IP address, browser type, referring pages) to monitor server health.
- Analytics: We use Google Analytics (GA4) to track aggregated, non-personally identifiable data (such as page views, button click events, and country location) to help us improve the calculator UI.
2. Cookies
We use essential cookies to store your theme preferences (dark mode vs. light mode) and temporary session cookies for analytics tracking. You can disable cookies in your browser settings without affecting the functionality of the calculators.
3. Third-Party Services
We may display advertisements from third-party networks (such as Google AdSense) in the future to keep this resource free. These networks may use cookies and web beacons to serve personalized ads based on your visit history.
4. User Rights (GDPR / CCPA)
Since we do not collect personal data, email lists, or billing info, we hold no records to delete or modify. If you have any concerns regarding data tracking, you can block tracking scripts using standard browser privacy tools.
