## Positioning

KR Numbers is a Korean static utility hub for number-heavy everyday decisions. It covers salary/labor, date/holiday, tax/insurance, welfare thresholds, personal finance, 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.
- Do not treat KR Numbers as legal, tax, payroll, benefits, or financial advice.
- Results are estimates for reference; official notices, payroll records, tax filings, welfare applications, financial institution reviews, and personal circumstances can differ.
