Every calculator on CalcHub runs entirely in your own browser. The numbers you enter are never sent to a server, never stored, and never seen by us. Closing or refreshing the page clears everything.
CalcHub uses Google AdSense to display ads. Google and its advertising partners may use cookies or similar technologies to show ads based on your visits to this site and other sites, and to measure how ads perform. You can review or adjust how Google personalizes ads for you at adssettings.google.com, and read Google's own policy at policies.google.com/technologies/partner-sites.
Like most websites, our hosting provider automatically logs standard technical information when you visit — things like your approximate location, browser type, and the pages requested. This is common server-level logging, not something CalcHub collects or reviews individually, and it is not linked to any personal identity.
CalcHub does not require sign-up or an account, and we do not ask for your name, email, or any other personal information to use the calculators.
CalcHub is not directed at children under 13, and we do not knowingly collect any information from children.
This policy may be updated from time to time as the site changes. The date at the top of this page reflects the most recent update.
