Privacy Policy
Short version: the sizing calculator runs in your browser, and btuwise does not collect personal data itself.
What we collect
btuwise is a static website of free mini-split guides and a BTU sizing calculator. The room details and numbers you enter into the calculator are processed entirely in your browser and are never sent to or stored on our servers.
Cookies & analytics
btuwise itself uses no tracking cookies. Where analytics are enabled, we use a privacy-friendly, cookieless service that only counts aggregate page views and does not identify you.
Advertising
btuwise may show ads through Google AdSense. Advertising partners such as Google may use cookies or similar technologies to serve and measure ads. You can review and control ad personalization in your Google account settings, and learn more in Google's own privacy and advertising policies.
Affiliate links

If you click an affiliate link and make a purchase or request a quote, btuwise may earn a commission at no extra cost to you. These partners set their own cookies and have their own privacy policies.
Third parties
Pages may link to external sources and partners (clearly marked). Those sites have their own privacy policies. btuwise does not sell or share data we don't collect.
