Data we collect
We do not collect the values you enter into our calculators. All calculations run in your browser. We may collect standard usage data (e.g. page views, device and browser type, approximate region) via analytics when you visit our site.
Analytics
We may use Google Analytics (or similar services) to understand traffic and improve the site. These services use cookies and process data according to their own policies. See Google Privacy Policy.
Advertising
We may show third-party advertisements (for example through Google AdSense). Advertisers may use cookies and similar technologies to measure performance, cap how often you see an ad, or show more relevant ads. Google uses cookies as described in How Google uses information from sites or apps that use our services. You can manage ad personalization for Google at Google Ad Settings. Where required by law, we will ask for consent before non-essential cookies.
Cookies
We use essential, analytics, and (where applicable) advertising cookies. Details are in our Cookie Policy. You can control cookies through your browser settings.
Third parties
Hosting, analytics, advertising, and sign-in providers may process limited data on our behalf. Each has its own privacy policy. We do not sell your personal data.
Children
CalcHub is not directed at children under 16. If you believe we have collected information from a child, contact us and we will take appropriate steps.
Changes
We may update this policy from time to time. The “Last updated” date reflects the latest version.
