1. What this policy covers
CalcHub ("we", "our") operates calc-hub.info. This policy explains what information we collect when you visit the site, why we collect it, and what choices you have. Using CalcHub means you accept the practices described here.
2. Calculator inputs
All calculations run in your browser. The numbers you type into any calculator never leave your device — we transmit nothing to a server, and we store nothing on our end. Your data stays on your screen.
3. Automatically collected data
Our server and third-party analytics tools collect: • Browser type and version • Operating system • Referring page URL • Pages visited and time on page • Country and city (derived from IP address, not stored directly) We use this data only to understand how people use the site and to fix problems.
4. Cookies
We use three categories of cookies: • Analytics cookies (Google Analytics) — track page views and sessions so we can see which calculators people use most. • Advertising cookies (Google AdSense) — serve relevant ads based on your browsing history across sites. Google manages these through DoubleClick. • Functional cookies — remember small preferences like your last calculator tab. You can block or delete cookies in your browser settings at any time. Doing so does not break the calculators.
5. Google AdSense
CalcHub displays ads through Google AdSense. Google uses cookies to show ads relevant to your interests based on your visits to this site and others. You can opt out of personalised advertising at google.com/settings/ads or aboutads.info. Google's full data policy lives at policies.google.com/technologies/partner-sites.
6. Google Analytics
We run Google Analytics to see aggregate traffic patterns — which pages are popular, which devices people use, where visitors come from. Google processes this data under their own privacy policy. To stop Analytics tracking you across all sites, install the Google Analytics Opt-out Browser Add-on at tools.google.com/dlpage/gaoptout.
7. Third-party links
Some pages link to external websites. We have no control over those sites or their privacy practices. Check their policies directly before sharing personal information with them.
8. Children
CalcHub serves students of all ages. We do not knowingly collect personal data from anyone under 13. If you believe a child submitted personal information here, contact us and we will delete it promptly.
9. Policy changes
When we update this policy, we change the "Last updated" date at the top of this page. Continued use of CalcHub after a change means you accept the new terms.
