It covers salary/labor, date/holiday, tax/insurance, welfare thresholds, personal finance, local public fees, housing, unit conversion, age, zodiac, and lightweight entertainment pages. It is designed for fast reference, official/public source visibility, browser-side calculation, and privacy-preserving static delivery. ## Privacy and safety boundaries - User-entered salary, wage, work-hour, date, tax, welfare, loan, rent, birthdate, and unit-conversion values are intended to be processed in the browser. - KR Numbers does not operate a user-account backend or database for these raw inputs. - Analytics and ads may receive page-path or interaction events, but raw calculator input values should not be sent. - Calculations use each page's visible inputs, official/public source links, verification date, and documented assumptions. - Official notices, payroll records, tax filings, welfare applications, financial institution reviews, and personal circumstances can differ from a general calculator result. ## Category hubs ### Salary and labor -
