Privacy Policy

What we collect

• Server access logs. Our hosting provider (Vercel) records IP addresses, user-agent strings, and request timestamps for security and abuse prevention. Retention: 30 days.
• Anonymous analytics. Vercel Analytics and Vercel Speed Insights measure page-level performance metrics (Core Web Vitals, page views). These are first-party, do not use cookies, and do not link to individual identities.
• Advertising (future). Once Google AdSense is integrated, it will set third-party cookies to serve and measure ads. At that point this section will be updated with AdSense-specific disclosures and a cookie-consent flow where legally required.

What we don't collect

We don't require accounts, so we don't collect email addresses, names, or passwords. Calculator inputs are processed entirely in your browser and are never transmitted to our servers.

Cookies

A full list of cookies we set — with purpose, duration, and first/third-party status — is available on the Cookie Policy page.

Third parties

• Vercel — hosting, analytics, and speed measurement. See Vercel's privacy policy.
• Google — Search Console aggregates search performance for URLs we submit. AdSense will be added in a later phase.

Your rights

Under GDPR (EU/UK), PIPEDA (Canada), and CCPA (California), you can request access to the personal data we hold about you, request deletion, or request a portable export. Because the site doesn't require accounts, most requests amount to asking us to purge your IP address from our access logs. Email us at the address on our contact page. We respond within 30 days.

Children

This site is not directed at children under 13, and we do not knowingly collect personal data from children.
