Privacy

This site uses Cloudflare Web Analytics only. It is cookie-free, fingerprint-free, and stores no personal data. We do not run Google Analytics, Meta Pixel, or any cross-site tracker.

What we collect

• Aggregated pageview counts (Cloudflare Web Analytics).
• Search Console query data (Google Search Console), anonymized and aggregated.

What we do NOT collect

• Account information (no logins).
• Inputs to calculators. All math runs in your browser; inputs never leave your device.
• Cross-site identifiers.

Advertising

Display ads may appear on high-traffic pages once a minimum traffic threshold is met. At that point, third-party ad networks may set cookies for ad personalization; those are governed by the ad network's own privacy policy, not this one.

AI crawlers

This site explicitly allows GPTBot, PerplexityBot, ClaudeBot, Googlebot, and Bingbot. We do not block LLM crawlers.
