Calculator inputs and share links
Calculations run in your browser. The calculators do not automatically send the numbers you enter to a calculation service. Copying a share link puts the chosen values in the URL. When that link is visited, its URL and those values may appear in hosting access logs and browser history. Share only values you want to disclose, and do not enter confidential information.
Website hosting
CalcPatch is hosted by Namecheap. Requests for pages and files may produce standard access logs containing an IP address, requested URL, browser information, and request time. These records support delivery, security, and troubleshooting. See Namecheap’s privacy policy for information about its practices.
Cookies, advertising and analytics
CalcPatch currently has no user accounts, advertising network, or third-party analytics scripts. The calculator code does not set tracking cookies or save calculator entries in local storage. We use system fonts and serve calculator code and styles from this site. If analytics or advertising is added, this policy and any necessary consent controls will be updated before those services are enabled.
External links
Reference links open other websites, which have their own privacy practices. Copy and share buttons use your browser’s clipboard or display text for you to copy; they do not submit a report to CalcPatch.
