Privacy Policy

Effective November 7, 2026

This English version is provided for convenience. If the two versions differ, the Korean version prevails.

What we collect

• Sign-in: email, name and the profile information your sign-in provider shares
• Watchlist: account identifier, the stocks you pick and when you added them
• Access logs: IP address, browser information and request logs kept by our hosting provider while operating the service
• Visit statistics: pages viewed (including search terms), referrer, browser and device type, approximate location and an anonymous visitor identifier

You can view filing data without signing in. Sign-in is needed only to save a watchlist.

Why we use it

Sign-in, saving your watchlist, operating the service and checking errors, understanding usage, and answering inquiries. We do not use it for advertising or sell it.

How long we keep it

Account information and watchlists are kept until you close your account or ask for deletion, and are deleted promptly on request. Information that law requires us to keep is kept for that period. Visit statistics are kept for the analytics tool's retention period and are not linked to your account.

Processors and international transfer

We entrust processing to the providers below. All are located in the United States, and data moves over the network while you use the service.

• Clerk: sign-in and account management
• Vercel: website hosting, access logs, visit statistics
• Neon: database storage (watchlist)
• PostHog: visit statistics

We do not share data with anyone else except where the law requires it.

Cookies

We use a cookie to keep you signed in and a cookie to tell visitors apart anonymously. We do not use advertising tracking cookies. If you block cookies, you can still view filing data but cannot sign in.

AI connection (MCP)

MCP works without sign-in and receives only the search terms and stock information sent when a tool is called. We do not receive your conversations with the AI.

Personal information in filings

Holder names and stakes are organized from data published on the Financial Supervisory Service's DART. If something is wrong, contact us below and we will check and correct it.

Your rights

You may ask to access, correct or delete your data, or to stop its processing. Send requests to the contact below.
