CommercialCalc ("we," "us," or "our") operates the website at commercialcalc.com. This Privacy Policy explains what information we collect, how we use it, and your rights regarding your information.
By using CommercialCalc, you agree to the collection and use of information in accordance with this policy.
H2: Information We Collect
Information you provide directly
We only collect personal information when you voluntarily submit it — for example, when you use the contact form. This may include your name and email address. We do not sell, rent, or share this information with third parties.
Information collected automatically
When you visit CommercialCalc, we automatically collect certain information through Google Analytics 4, including:
- Pages visited and time spent on each page
- Browser type and operating system
- Approximate geographic location (country and region level only)
- Referring website
- Device type (desktop, mobile, tablet)
This data is anonymous and aggregated. It does not identify you personally. We use it solely to understand how the site is used and to improve the tools and content.
Calculator inputs
The numbers you enter into our calculators are processed entirely in your browser. They are never transmitted to our servers and are never stored. When you close or refresh the page, your inputs are gone.
H2: Cookies
CommercialCalc uses cookies only for the following purposes:
- Google Analytics cookies — anonymous usage tracking as described above
- Essential cookies — required for basic site functionality
We do not use advertising cookies, tracking pixels, or third-party marketing cookies.
You can disable cookies in your browser settings at any time. Disabling analytics cookies will not affect your ability to use any calculator on the site.
H2: Google Analytics
We use Google Analytics 4 to understand how visitors use the site. Google Analytics collects anonymous usage data and stores it on Google's servers. Google's privacy policy is available at policies.google.com/privacy.
You can opt out of Google Analytics tracking by installing the Google Analytics opt-out browser add-on, available at tools.google.com/dlpage/gaoptout.
H2: Third-Party Services
CommercialCalc uses the following third-party services:
- Google Analytics 4 — anonymous usage analytics
- Vercel — website hosting and content delivery

Each of these services has its own privacy policy. We do not control how these third parties handle data.
H2: Data Security
We take reasonable technical measures to protect information submitted through the contact form. However, no method of internet transmission is 100% secure.
Calculator inputs are never transmitted to any server. They exist only in your browser during your session.
H2: Children's Privacy
CommercialCalc is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has submitted personal information through our contact form, please contact us and we will delete it promptly.
