Visitor statistics & privacy.
How visitor counts are measured
The homepage displays the number of recorded browser sessions since the counter was activated, plus recorded sessions for the current Asia/Seoul calendar day. These numbers do not represent unique people, historical visits before activation, or verified human-only traffic.
The site stores one anonymous counter event in an existing Vercel Blob store for a new browser session. A 30-minute first-party HttpOnly, Secure, SameSite=Lax cookie prevents repeated counting within that interval. The event is an anonymous browser-session record; for events from 2026-11-01 R9 onward only the initial page pathname (without URL query parameters) is additionally included. IP addresses, user-agent strings, email addresses and names are not written to the visit-event objects. Session entry pages are not full pageview statistics.
Browsers with Do Not Track enabled can read aggregate counts without creating a new event. Cookies may still be used for session control on counted visits. No guessed or simulated visit values are shown if the counter is unavailable.
실제 브라우저 세션 집계이며 고유 인원수는 아닙니다. 첫 방문 시 30분간 유지되는 1차 당사자 쿠키로 중복 집계를 줄입니다. 방문 기록에 이메일·이름·IP 주소·기기 식별자를 저장하지 않습니다.
