Privacy Policy

Your data is your business. Keeping it safe is ours.

Last Updated: May 10, 2026

At CalcHub Pro, we believe that high-quality digital tools shouldn't come at the cost of your personal privacy. This policy outlines exactly how our platform operates, what minimal data we collect, and how we protect you.

1. Client-Side Data Processing

CalcHub Pro is built on advanced client-side JavaScript architecture. This means we do not collect, store, transmit, or share any personal information or numbers you enter into our calculators. All math and data processing happens locally inside your own web browser. Once you close or refresh the page, your data is permanently gone. We have absolutely no database storing your financial, health, or text inputs.

2. Google AdSense & Cookies

To keep our suite of tools 100% free for all users, we use Google AdSense to display advertisements. Google, as a third-party vendor, uses cookies (specifically the DART cookie) to serve ads based on your visit to CalcHub Pro and other sites on the internet.

You may proactively opt out of the use of the DART cookie by visiting the Google Ad and Content Network Privacy Policy.

3. Analytics & Log Files

Like almost all professional websites, CalcHub Pro utilizes standard log files. The information collected in these logs is strictly anonymous and includes internet protocol (IP) addresses, browser type, Internet Service Provider (ISP), date/time stamps, referring/exit pages, and the number of clicks. We use this non-identifiable data exclusively to analyze trends, administer the site, and improve user experience.

4. Contact Information

If you have any questions or require further information regarding our Privacy Policy, please feel free to reach out. We are committed to transparency and ensuring your experience on CalcHub Pro is safe and productive.
