GrownUpMath ("we", "us", or "our") operates the website grownupmath.net. This Privacy Policy explains how we collect, use, and protect information when you visit our site.

Information We Collect

GrownUpMath is a collection of free, client-side calculators. We do not collect, store, or transmit any personal data you enter into our calculators. All calculations run entirely in your browser — no data is sent to our servers.

Local Storage and Tracking Technologies

We use the following browser technologies:

• Local storage — saves your theme preference (light/dark mode). This data never leaves your browser

Third-Party Services

We use the following third-party services:

• Cloudflare — hosting and CDN. Cloudflare may collect basic analytics (page views, visitor country, IP address, browser type) at the network level. See Cloudflare's Privacy Policy
• Google Fonts — web fonts loaded from Google's servers. See Google Fonts Privacy

Data Retention

Since we do not collect personal data through our calculators, there is no personal data to retain. Analytics data collected by third-party services is subject to their respective retention policies.

Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated revision date.
