Privacy Policy
Last updated: August 17, 2026
Jay Kim ("this site") takes visitor privacy seriously. This page explains what information the site collects and how it is used.
01Information collected
You can browse this site without registering. If you only read pages, no personal information such as your name or contact details is collected directly.
Information is collected only in these cases:
- When you contact the site by email: your email address and the message content
- When you sign in to use certain features (such as the vocabulary tool): the minimum information needed to identify your account
- Server access logs: IP address, browser type, and access time, kept for security and error handling
02How it is used
Collected information is used only to reply to enquiries, provide and debug the service, and produce aggregate statistics. It is not used for any other purpose and is never sold to third parties.
03Cookies and advertising
This site may use cookies for visitor analytics and for serving advertisements.
Third-party vendors, including Google, may use cookies to serve ads based on your prior visits to this site. Google's use of advertising cookies enables it and its partners to serve ads based on your visits to this site and other sites.
You can opt out of personalised advertising at any time through Google Ads Settings. You may also block cookies in your browser settings, though some features may then stop working correctly.
04Retention
Enquiry messages are deleted within one year after they are answered. Server access logs are kept for at most three months. Account information is deleted immediately on request.
05Your rights
You may request access to, correction of, or deletion of your information. Contact the email address below and the request will be handled after verification.
06Changes
If this policy changes, the updated version and its date will be posted on this page. Significant changes will be announced prominently.
