PRIVACY POLICY

개인정보처리방침

Effective date: July 31, 2026 · 시행일: 2026년 7월 31일

1. Overview · 개요

T.T.WORLD minimizes data collection and processes only the information needed to operate the website, remember preferences, support rankings and provide online game functions.

T.T.WORLD는 웹사이트 운영, 환경설정 기억, 랭킹 및 온라인 게임 기능 제공에 필요한 범위에서만 정보를 처리합니다.

2. Information processed · 처리하는 정보

• Browser storage: player nickname, music on/off and volume preferences stored in the browser’s local storage.
• Account: when Google login is selected, Firebase Authentication processes the Google account identifier and authentication status. T.T.WORLD stores the separate public game nickname chosen by the user and does not store the Google password.
• Online play: Firebase authentication identifier, room membership, ready state, match state, attacks, previews and other temporary multiplayer data.
• Personal records and rankings: public game nickname, game/mode, cleared lines, play time, score, win count, play count and achievement time when a result is submitted. Personal records are readable only by the signed-in account; leaderboard entries and public nicknames are visible to authenticated visitors.
• Technical records: Firebase Hosting and security logs may include IP address, access time, browser and device information.
• Contact: the sender’s email address and the contents of an inquiry when the user contacts T.T.WORLD by email.
• Advertising: if Google AdSense is enabled, Google may process cookies, device identifiers, IP address and advertising interaction data under its own policies.

3. Purposes · 처리 목적

Information is used to remember user preferences, connect and synchronize online matches, operate rankings, protect service integrity, diagnose errors, respond to inquiries and—only when configured—display advertising on the main selection screen.

4. Retention · 보유기간

• Browser preferences remain until the user clears the site’s browser data.
• Room, matchmaking and live match data is temporary and may be deleted, expired or overwritten as part of service operation.
• Google-linked personal records and ranking records may remain until replaced, the ranking service is reset, the account data is deleted, or a valid deletion request is processed.
• Hosting and security logs follow the retention settings of the relevant Google Firebase service.
• Email inquiries are kept only as long as reasonably needed to answer and document the request.

5. Service providers · 외부 서비스 제공자

T.T.WORLD uses Google Firebase Hosting, Firebase Authentication (anonymous and optional Google sign-in) and Firebase Realtime Database. Google AdSense is prepared but is not requested unless advertising, valid ad-unit IDs and the required consent state are all configured. These Google services may process data under the Google Privacy Policy.

6. Advertising, cookies and consent · 광고·쿠키·동의

Advertising is limited to the main game-selection screen and is never displayed while a game is open. T.T.WORLD’s own promotion panels do not make Google advertising requests and are visually identified as promotions.

Before personalized advertising is requested in a region where consent is required, T.T.WORLD will use an applicable Google-certified consent management platform. If the required consent state is pending, rejected or unavailable, the advertising module does not request Google ads.

7. User choices and rights · 이용자 선택권

Users may sign out of Google login, clear locally stored preferences through browser settings, leave an online room to stop live synchronization, and block or reject advertising cookies through available browser or consent controls. Questions, access requests and deletion requests for a profile or personal game records can be sent through the Contact page.

8. Children · 아동

T.T.WORLD is a general-audience arcade and does not intentionally request a child’s real name, address or other sensitive personal information. A parent or guardian may contact T.T.WORLD regarding a child’s information.

9. Changes · 정책 변경

Material changes will be reflected on this page by updating the effective date. Continued use after an update is subject to the revised policy.
