Privacy Policy

Last updated: May 2026

Short Version

We do not collect, store, sell, or share your personal information. Everything our calculators and tools do happens directly in your browser. Nothing is sent to our servers because we don't have those kinds of servers.

What We Do Not Collect

• Your name, email, or any account information (we don't have accounts)
• The numbers or text you type into our calculators
• The results our calculators generate
• Your IP address (beyond standard server logs from Cloudflare for security)
• Tracking cookies or fingerprinting data

What Happens In Your Browser

All calculations happen locally on your device using JavaScript. When you type into a calculator, that data never leaves your browser. When you close the tab, everything is gone.

Cookies

We do not set any first-party tracking cookies. Some browser-required cookies may be set by Cloudflare (our hosting provider) for security and CDN functionality.

Third-Party Services

We use the following third-party services:

• Cloudflare Pages — hosts our website. Cloudflare may collect standard server logs (IP, user agent, request paths) for security and performance. See Cloudflare's privacy policy.
• Google Fonts — used for typography. Google may receive your IP address when fonts are loaded.
• Google AdSense (when added) — displays advertisements. Google may use cookies to serve ads based on your visits to this and other sites. You can opt out of personalized advertising by visiting Google's Ads Settings.

Children's Privacy

This site is intended for general audiences. We do not knowingly collect any information from children under 13. If you believe we have, please contact us so we can address it.

Changes to This Policy

If we make changes to this policy, we will update the "Last updated" date at the top of this page. Significant changes will be noted on the homepage.
