Privacy Policy
This privacy policy explains what information CalcKit collects and how it is used. The short version: almost nothing. All 280 calculators run locally in your browser, so the numbers you enter — your weight, income, loan balance, or measurements — never leave your device. There are no accounts, no sign-up forms, and no server-side storage of your inputs or results. Clearing your browser data removes anything stored locally. Third-party advertising partners, including Google AdSense, may use cookies to serve personalized ads based on your prior visits to this and other websites. You may opt out of personalized advertising through Google Ads Settings. We do not collect personal information beyond standard, aggregated analytics used to understand which calculators are most useful.
