HVACToolSuite ("we," "us," or "our") operates hvactoolsuite.com. This policy explains what data we collect, how we use it, and your rights. We are committed to protecting your privacy and being transparent about our practices.
Data We Collect
HVACToolSuite is a client-side calculator. All calculations run in your browser — no form data, HVAC inputs, or calculation results are transmitted to or stored on our servers.
We collect limited data through standard web infrastructure and advertising partners:
- Usage analytics: Page views, browser type, device type, and general location (city/country level) collected through Google Analytics.
- Advertising data: Google AdSense may use cookies and similar technologies to serve personalized ads based on your browsing history. See the Google AdSense section below.
- Server logs: Standard web server logs including IP address, access times, and referring URLs, retained for security and performance purposes.
Google AdSense
We use Google AdSense to display advertisements on this site. Google AdSense uses cookies to serve ads based on your prior visits to this and other websites. You may opt out of personalized advertising by visiting Google Ads Settings. Google's use of advertising cookies is governed by the Google Privacy Policy.
How We Use Data
- To understand how visitors use the site and improve the calculator experience
- To display relevant advertisements that help keep the service free
- To maintain site security and diagnose technical issues
We do not sell your personal data to third parties. We do not use your data to build personal profiles beyond what is described above.
Cookies
This site uses cookies set by Google Analytics and Google AdSense. These cookies are used for analytics and ad personalization. You can manage or disable cookies through your browser settings. Note that disabling cookies may affect the display of ads but will not affect the calculator functionality, as all calculations run locally in your browser.
