Privacy Policy

Last updated: August 24, 2026

Your privacy matters. This page explains what information the Euler's Method Calculator collects, if any, and how it is handled. The short version: all calculations run locally in your browser, and we do not collect any personal data.

What We Collect

We do not collect, store, or transmit any personal information. The Euler's Method Calculator is fully client-side — your equations, step sizes, results, and graphs are computed on your own device.

Local Storage

The only data stored on your device is a single setting that remembers your preferred color theme (light or dark). This is stored in your browser's local storage and never leaves your device. You can clear it at any time through your browser's settings.

Analytics and Cookies

We do not use analytics trackers, advertising cookies, or third-party tracking of any kind. No cookies are set by this site beyond the local theme preference described above.

Third-Party Services

We do not sell, rent, or share your information with any third parties. There is nothing to share — we collect nothing.

Children's Privacy

This site is suitable for everyone, including students and educators. Since no personal information is collected, there are no special protections needed beyond what is described here.

Changes to This Policy

If this policy ever changes, the updated version will be posted on this page with a new revision date.
