mCalculator does not require accounts, logins, or personal information to use any calculator. The numbers you enter into a calculator are processed entirely in your browser and are never sent to our servers.
Cookies and analytics. mCalculator may use analytics tools such as Google Analytics to understand website traffic, how visitors interact with our calculators and pages, general device and browser information (such as browser type, operating system, and approximate location derived from IP address), referring sites, and page performance. These analytics services may set cookies or use similar technologies (such as local storage or pixels) to collect this information in aggregated, privacy-respecting form. We use this data only to improve the site, fix errors, and prioritize which calculators to build next. We do not sell or share individual usage data, and we do not use analytics to identify you personally. You can opt out by using browser controls, privacy extensions, or the Google Analytics opt-out add-on.
Advertising. Pages on this site may display third-party advertisements. Advertising partners may use cookies to measure and personalize ads in accordance with their own privacy policies. You can manage advertising preferences through your browser settings.
Children. mCalculator is intended for general audiences and is not directed to children under 13.
Changes. We may update this policy from time to time. Material changes will be reflected by an updated date at the bottom of the page.
