CalcQuarry (“we”, “us”, “our”) operates calcquarry.com, a free set of construction and home-project calculators and guides. This policy explains what information is collected when you visit the site and how it is used.
Information we collect
Calculator inputs. The numbers you type into a calculator (for example length, width and depth) are used to produce your result in your browser. We do not ask you to create an account and we do not ask for your name to use a calculator.
Log and technical data. Like most websites, our hosting provider (Cloudflare) processes technical data such as IP address, browser type, device type, pages visited and time of visit. This is used to deliver the site, keep it secure and understand how it is used.
Contact information. If you email us, we receive your email address and the content of your message, and we use it to reply.
Analytics
We use privacy-focused and standard analytics tools to understand which pages are useful:
- Cloudflare Web Analytics measures page views and performance.
- Google Analytics / Google Site Kit collects information about how visitors use the site, such as pages viewed and approximate location. Google’s use of this data is described in its own policy. You can opt out with a Google Analytics Opt-out Browser Add-on.

- Third-party vendors, including Google, use cookies to serve ads based on a user’s prior visits to this and other websites.

Data retention and security
We keep contact emails only as long as needed to respond. We rely on our hosting provider, Cloudflare for security, and no method of transmission over the internet is perfectly secure.
