Privacy policy

Effective: October 9, 2026

This is an English translation of the Korean privacy policy of 셈장부 (WonLedger, "this site"). If the two versions differ, the Korean version applies. This site values your privacy and complies with Korea's Personal Information Protection Act and related laws.

1. Information we do not collect

This site has no sign-up and does not collect any information that identifies you, such as your name, email address, phone number or national ID number.

Everything you enter into a calculator — salary, loan amount, deposit, dates of employment and so on — is processed only inside your browser. These values are not sent to this site's servers, are not stored or logged in any form, and disappear as soon as you leave the page.

For convenience, your light or dark mode choice and the ticked items on checklists are kept in your browser's local storage on your device only. They are never sent to a server and are deleted when you clear this site's data in your browser. When you use "Copy link to these inputs", your inputs are placed after the # in the link; that part of the address is not sent to the server or to analytics tools either.

2. Cookies and automatically collected information

This site uses third-party services to show ads and to measure visits, and these services may use cookies and similar technologies. Information that may be collected this way includes:

This information is not used to identify you. It is used only to improve the site and to measure ad performance.

3. Third-party advertising and analytics

Google AdSense

This site shows ads provided by Google and its partners. Third-party vendors, including Google, use cookies to serve ads based on your visits to this site and other websites.

You can read how Google uses advertising cookies (including the DoubleClick cookie) and how it handles the information collected in Google's advertising privacy page.

To turn off personalized ads, use Google Ad Settings. You can also opt out of third-party vendors' use of cookies at www.aboutads.info.

Google Analytics

This site may use Google Analytics to count visits. The information is not used to identify individuals. To opt out, you can install the Google Analytics opt-out browser add-on.

4. How to refuse cookies

You can block or delete cookies in your browser settings. If you block all cookies, some features may not work properly.

5. Retention and deletion

Because this site does not collect personal information, it has none to keep or delete. Information collected through third-party services is kept according to each provider's own policy.

6. Your rights

You may ask at any time to see, correct, delete or stop the processing of your information. As this site holds no personal information itself, requests about information collected by third-party services should be made to those providers directly.

7. Linked sites

This site links to external sites such as the National Tax Service and other public agencies. We are not responsible for how those sites handle personal information; please check their own policies.

8. Changes to this policy

If this policy changes, the changes and the effective date will be posted on this page. Changes that are unfavorable to users will be announced at least seven days before they take effect.

9. Contact
