Static hosting

This site consists entirely of static HTML, CSS, and JavaScript files, with no backend server or database.

In-browser calculation

All salary calculations run locally in your browser. The salary, family count, non-taxable pay, and other values you enter are never sent to a server.

Local and session storage (localStorage, sessionStorage)

This site uses browser storage only for:

• Remembering whether you dismissed the English-language suggestion banner (Korean homepage only) - stored in sessionStorage, so it's forgotten once you close the browser tab (kept only for the current session).
• Optionally remembering your last-used, non-sensitive calculator values so they're pre-filled on your next visit - stored in localStorage.

Use the "Clear saved values" button at any time to delete the saved calculator values.

Share links (URL query parameters)

"Copy share link" encodes your calculator inputs (salary, month, non-taxable pay, family count, children, withholding percentage, social-insurance toggles) into the page URL. It never includes your name, nationality, visa status, or specific employer information.

No accounts or database

There is no sign-up, login, or user-account system, and no server-side storage of your inputs.

Analytics and advertising

This site does not currently use any analytics tool. Ad containers exist in the page markup but are hidden by default, and no advertising cookies are used until real advertising is enabled. This policy will be updated if that changes.
