Privacy Policy

Effective: June 2026

• The calculator runs entirely in your browser. What you type (room size, climate zone, etc.) is never transmitted, stored, or logged by us.
• No accounts, no forms, no email collection.
• No cookies set by this site.
• Analytics: we use Cloudflare Web Analytics, a privacy-first, cookie-less measurement tool. It does not use client-side state, does not fingerprint individuals, and does not track you across sites (Cloudflare's description). We see aggregate page views — nothing about you.
• Outbound links: manufacturer/retailer links lead to sites with their own privacy policies. Affiliate links, when active, pass a referral code to the retailer — see the disclosure.
• Advertising: this site currently serves no display ads. If ad networks are added later, this policy will be updated first with the networks named and their cookie behavior described.
• Hosting: served as static files via Cloudflare; Cloudflare's edge logs (IP, user agent) are governed by Cloudflare's privacy policy.

Questions? This is a static site with no backend — there is genuinely nothing to request a copy of.
