Privacy Policy
This policy explains what information Mathify.net collects, how it's used, and the choices you have. We've kept it short because we collect very little.

Calculator inputs stay in your browser
Every calculator on Mathify.net — including the mortgage, loan, BMI, calorie, grade, GPA, and other tools — runs entirely client-side, in your browser. The numbers, dates, and other details you enter are used only to compute the result shown on your screen. They are not transmitted to our servers, stored in a database, or shared with any third party.
Information we may collect
Like most websites, our hosting and analytics providers may automatically log basic technical information, such as your approximate location, browser type, device type, and the pages you visit, in aggregate form. This is used only to understand overall site traffic and improve performance — it is never combined with the specific figures you type into a calculator.
Cookies
We may use minimal, privacy-friendly cookies or local storage to remember simple preferences, such as your light or dark theme choice. These do not identify you personally on their own.
Advertising
Mathify.net displays advertising served by Google AdSense. Google and its advertising partners may use cookies — including the DoubleClick cookie — to serve ads based on your prior visits to this and other websites. This may include personalized advertising based on your browsing activity.
You can opt out of personalized advertising by visiting Google's Ads Settings, or opt out of third-party vendor use of cookies for personalized ads by visiting aboutads.info. For more on how Google uses information from sites that use its services, see Google's Partner Sites policy.
Third-party links
Some pages may link to external resources for further reading. We aren't responsible for the privacy practices of those third-party sites, and we encourage you to review their own policies before sharing information with them.
Children's privacy
Mathify.net is a general-audience tool and does not knowingly collect personal information from children. Since the site does not require sign-up or personal details to function, no such information is requested from any user.
Changes to this policy
We may update this policy from time to time to reflect changes to the site or applicable law. Any changes will be posted on this page with an updated revision date.
