1. Information we collect

Korea Data Tools has no accounts, comments or forms that send data to us. The numbers you type into a calculator stay in your browser and are never sent to our server.

Like most websites, the hosting service and third-party services may automatically record technical information such as your IP address, browser type, operating system, the time of your visit and the pages you view.

2. Cookies and advertising

This site uses Google AdSense to show ads.

• Third-party vendors, including Google, use cookies to serve ads based on your previous visits to this website or other websites.
• Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the internet.
• You can opt out of personalized advertising in Google Ads Settings, or opt out of some third-party vendors' cookies at www.aboutads.info.

3. Exchange rates

The Man/Eok converter loads a public exchange rate from ExchangeRate-API (open.er-api.com). This request does not include anything you type.

4. Refusing cookies

You can block or delete cookies in your browser settings. Some features may not work fully if you do.

5. Retention

We do not store personal information ourselves. Information collected by third-party services is kept and deleted under their own policies.
