Pieceproof can be played on this website (“Web”) and on CrazyGames. The two are handled differently, so they are described separately below.

한국어 요약

개인정보 처리자 및 개인정보 보호책임자: 공경훈 · 연락처: [email protected]

• 게임 진행 기록(스테이지, 별, 데일리 결과, 설정)은 브라우저(localStorage)에만 저장되며 저희에게 전송되지 않습니다.
• 플레이 통계는 동의한 경우에만 수집합니다(세 번째 스테이지 클리어 후 결과 화면에서 한 번 묻습니다). 동의하지 않아도 모든 기능을 똑같이 쓸 수 있습니다.
• 근거: 정보주체의 동의(개인정보 보호법 제15조 제1항 제1호, 제28조의8 제1항 제1호).
• 수집 항목: 게임 이벤트(스테이지 시작/클리어/실패, 이동, 힌트 사용, 데일리 결과), 로딩 시간, 기기 종류, 브라우저 언어, 빌드 버전, 브라우저에 저장되는 임의 ID(가명). 이름, 이메일, 계정, 정밀 위치, 광고 ID, 쿠키는 수집하지 않습니다.
• 목적: 난이도 균형과 성능 개선.
• 국외 이전 및 수탁자: PostHog Inc.(2261 Market Street #4008, San Francisco, CA 94114, USA, [email protected])에 처리를 위탁하며, 플레이 중 이벤트가 발생할 때마다 암호화된 연결(HTTPS)로 미국(PostHog US 클라우드)에 전송됩니다.
• 보유 기간: 수집 후 최대 1년, 이후 삭제.
• 거부 및 철회: 안내에서 "안 함"을 누르거나 언제든 설정 > 통계에서 끌 수 있습니다. 끄면 즉시 전송이 멈추고 브라우저의 임의 ID가 삭제됩니다.
• 권리 행사: 열람, 정정, 삭제, 처리정지 요청과 이미 전송된 통계의 삭제는 통계 ID(게임 메뉴 → ID 복사)와 함께 위 이메일로 요청해 주세요.
• CrazyGames 버전은 자체 분석 기능이 없고 PostHog나 저희에게 데이터를 보내지 않습니다.

Game progress (stages, stars, daily results, settings) is stored only in your browser (localStorage). It is not sent to us. Clearing site data deletes it.

Gameplay statistics are off unless you say yes. A small prompt asks once, on the result screen after your third stage clear (never during play, never on your first clear). “Allow” and “No thanks” are equal; closing the prompt counts as “No thanks”, and you can keep playing without answering. Until you agree, nothing is sent and no identifier is created or stored. If your browser sends Do Not Track or Global Privacy Control, the prompt is not shown and statistics stay off.

If you agree, the following applies:

• Legal basis: your consent (PIPA Art. 15(1)1 and Art. 28-8(1)1; GDPR Art. 6(1)(a) where applicable).
• Data items: game events (e.g. stage started/cleared/failed, moves, hints used, daily result), load time, device type (mobile/desktop), browser language, build version, and a random pseudonymous ID stored in your browser. No name, email, account, precise location, advertising ID or cookies. The data is pseudonymous, not anonymous: the random ID links events from the same browser.
• Purpose: improving difficulty balance and performance.
• Recipient and transfer abroad: PostHog Inc., 2261 Market Street #4008, San Francisco, CA 94114, USA ([email protected]), acting as our processor. Data is transferred to the United States (PostHog US cloud) over an encrypted connection (HTTPS) at the moment each event occurs during play.
• Retention: at most 1 year after collection, then deleted.
• Refusing or withdrawing: choose “No thanks” (or close the prompt), or withdraw at any time in Settings > Stats. The same details are shown under “Details” in the prompt and in Settings. Turning it off stops sending immediately and deletes the random ID from your browser. Refusing has no effect on the game: every feature works the same.
• Your stats ID: while statistics are on, the game menu shows the random ID with Copy ID and Reset ID. Reset ID switches to a new random ID and clears statistics not yet sent from this device. Neither Reset ID, turning statistics off, nor clearing your browser data deletes statistics that were already sent: the game cannot delete server data.

The CrazyGames version of Pieceproof contains no analytics of its own and sends no data to PostHog or to us. Game progress is saved through the CrazyGames data module (or kept in memory only if that module is unavailable). Ads, accounts and consent on CrazyGames are handled by CrazyGames under the CrazyGames privacy policy.

You may request access to, correction, deletion or suspension of processing of personal information about you, and withdraw consent at any time, by contacting [email protected]. To delete statistics already sent, email [email protected] with your stats ID (game menu → Copy ID); we delete the data linked to that ID on request. Statistics are pseudonymous, so the ID is the only way to find them. Copy your ID before you press Reset ID or turn statistics off: after that the old ID is gone from your browser and we cannot locate its data.

Complaints: you may file a complaint with the Personal Information Protection Commission (Korea, privacy.go.kr, call 182) or the Korea Internet & Security Agency privacy center (privacy.kisa.or.kr, call 118), or with the data protection authority where you live.
