Who Operates This Site

CalcHub is operated by Cloudtopia, an Ontario, Canada company. References in this policy to “we,” “us,” or “CalcHub” refer to the site and its operator.

Information We Collect

CalcHub does not require an account or collect personal information. Calculator inputs are processed entirely in your browser and are never sent to our servers.

Analytics

We use Google Analytics 4 (GA4) to understand how visitors use the site. GA4 may collect anonymized data including pages visited, time on site, device type, and approximate geographic location. You can opt out of Google Analytics by installing the Google Analytics Opt-out Browser Add-on.

Advertising

We display advertisements through Google AdSense and potentially other ad networks. These services may use cookies and similar technologies to serve ads based on your prior visits to this site or other websites. You can opt out of personalized advertising by visiting Google's Ads Settings.

Affiliate Links

Some pages may include links to retailers (for example Home Depot, Lowe’s, or Amazon) that are affiliate links. If you click one of these links and make a purchase, we may earn a commission at no extra cost to you. Affiliate links are disclosed near the links themselves and are marked with rel="sponsored" per search-engine guidance. Commission income helps keep this site free for everyone.

Cookies

CalcHub itself does not set cookies. However, third-party services (Google Analytics, Google AdSense, and Pinterest features when enabled) may set cookies as described above. You can control cookies through your browser settings.

  • Google AdSense — display advertising
