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.

Affiliate links

Some pages may contain affiliate links: if you sign up for a recommended product through one, we may earn a commission at no cost to you. We only link to products relevant to the tool you are using, and commissions never influence the calculations — every rate table and formula on this site is sourced from government publications and verified against primary documents, independent of any commercial relationship. Affiliate links are marked where they appear.

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.
