Privacy Policy

Last updated: August 8, 2026

HomeCalcHub respects your privacy. Because this is a static website, we do not operate user accounts and we do not store any personal information on a server.

1. Information We Do Not Collect

Our calculators run entirely in your browser. The numbers you enter never leave your device and are never sent to us. If you share a result link, the inputs are visible in the URL — share carefully if the numbers are sensitive.

2. Cookies and Advertising

We plan to display ads through Google AdSense. Google and its partners may use cookies or similar technologies to serve ads based on your visits to this and other websites. Google uses advertising cookies to enable AdSense publishers to serve and manage ads, including personalized ads where permitted.

3. Analytics

We may use Google Analytics to understand aggregate traffic (for example, which pages are popular). This data is collected in anonymized form and helps us improve the site.

4. Your Choices

You can opt out of personalized advertising by visiting Google Ads Settings, or opt out of third-party cookies at aboutads.info. You can also block cookies in your browser settings.
