1. About the game

This policy applies to 四字熟語チャレンジ - 脳トレパズル, provided by zhufeng Xu, application identifier com.xuzengfei.jukugochallenge. The game offers Japanese four-character idiom puzzles, a local word journal and tea-house progress. It does not provide accounts, chat, cloud leaderboards, purchases or a separate developer analytics service.

2. Information kept on your device

Puzzle progress, collected words and stamps, tea-house decorations, audio and motion settings, selected language, the version for which a review was requested, and recent ad-display times are stored locally. Game code does not upload these records to a developer server. Operating-system backup settings may include local app data. The game does not request camera, microphone, contacts, photos or precise-location permissions. Checking whether other audio is playing at launch reads a local system status; it does not record sound.

3. Advertising and service data

The game integrates Google AdMob (Google Mobile Ads SDK) and Google User Messaging Platform (UMP). Ads can include optional rewarded ads for hints and occasional interstitial ads at completed-puzzle breaks. Google may process IP addresses and approximate location derived from them, device and advertising identifiers, app/device information, advertising data and interactions, crash logs, performance diagnostics and consent information. These data can be collected and shared with Google and advertising service providers for advertising, measurement, service operation and fraud prevention. Ads without personalization can still involve data processing. We do not operate our own advertising-data server.

4. Device identifiers and consent

On iOS and iPadOS, the game requests Apple App Tracking Transparency permission before updating Google UMP. Declining tracking does not block the puzzles. ATT permission is not treated as permission to request ads: actual UMP permission is checked separately. The system and your consent choices determine which advertising signals may be used. You can change tracking permission in Settings → Privacy & Security → Tracking.

5. Your privacy choices

The game updates UMP consent information at launch and displays a required consent form when the app can present it. Only UMP permission allows SDK initialization and ad requests. Where UMP requires it, the settings entry “広告のプライバシー設定” opens its privacy-options form. Settings also links to this policy. You can play the puzzles when ads are unavailable or you do not choose to view a rewarded ad.

6. Retention and requests

Local records remain until removed through operating-system app-data controls or uninstalling, subject to backup and restore settings. There is no game account to delete. Google determines retention for data it controls under its policies. To ask about developer-controlled data, including support correspondence, email q908267264@gmail.com with the game name and platform. Depending on your location, you may have rights to access, correct, delete or restrict processing, object to processing, withdraw consent, or contact a supervisory authority. Some requests concerning Google-controlled data may need to be directed to Google. Service providers may process information outside your country under applicable safeguards.

7. Children, security and updates

This is a general-audience puzzle game and is not directed to children under 13. We do not ask children to submit personal information. A parent or guardian who believes a child provided personal information can contact us. Google network services use encrypted connections, but no storage or network service can be guaranteed completely secure. We update this page when practices materially change.
