1Information handled directly by the app

The app has no account system and does not ask for your name, phone number, email address, contacts, photos, camera, microphone, or payment details. Level progress, high scores, move counts, card and skill progress, board-tool state, audio preferences, and privacy choices are stored locally on your device. Uninstalling the app normally removes this local data.

Only after consent, the app sends a randomly generated installation ID, app version, launches and active play time; stage entries, deaths, and completions; highest stage, best score and highest tile; and successful revive, undo, hammer, and Nova uses to our first-party analytics service. These events calculate DAU, WAU, MAU, new users, D1/D7/D30 retention, average play time and launches, stage pass rates, progress, and feature use.

First-party analytics does not read IDFA, hardware device identifiers, name, phone number, location, board contents, or ad interactions, and is not combined with advertising data. The installation ID resets on uninstall and is converted on the server into an irreversible pseudonymous digest.

2Anonymous analytics, advertising, and your choice

The app integrates the GroMore mediation SDK and Pangle advertising SDK. They are not initialized until you actively accept the in-app privacy notice. First-party analytics also stays off before consent. If you decline, the core game remains playable without analytics or advertising, while ad-funded revive, hammer, undo, and card-refresh features are unavailable and no between-stage full-screen ad is requested.

After consent, a rewarded ad may appear when you explicitly request a reward, and a full-screen ad may appear after every five completed stages. Ads should be clearly identified and provide a visible close or skip control.

3Third-party SDK disclosure

GroMore and Pangle are provided by Beijing Ocean Engine Network Technology Co., Ltd. and its affiliates. Depending on SDK version, device environment, system permissions, and ad context, the SDKs may process an IP address; IDFV and, only where authorized and available, IDFA; device model, operating system, language, time zone, screen, CPU, storage, memory, and system uptime; carrier, Wi-Fi, and network status; app bundle, version, and foreground/background state; and ad impression, click, playback, reward, and error events. The app itself does not request precise location permission.

This information is used for ad delivery, reward verification, attribution, frequency control, analytics, fraud prevention, security, and service stability. It is collected by the SDK after consent and transmitted over the network. Review the GroMore SDK Privacy Policy and the Pangle Advertising SDK Privacy Policy for current details.

4Sharing, sale, and international processing

We do not sell your personal information or share first-party analytics with advertising partners. After you consent to advertising, the SDK providers process information needed to provide the ad features described above. Their storage locations, service providers, and international transfer arrangements are governed by their current policies and applicable law.

First-party analytics is hosted on Tencent Cloud infrastructure in mainland China and is used only for this game's own operations. Network providers may process standard network information for transport, security, and troubleshooting, but receive no player account or combined advertising profile from us.

5Retention and deletion

Local game data remains until you reset the relevant progress, clear app data, or uninstall the app. Event-deduplication records are retained for no more than 120 days. Activity and progress records containing a pseudonymous installation digest are normally deleted within 24 months after the last activity; stage and feature aggregates that no longer contain the digest may be retained for trend analysis. Advertising SDK data is retained and deleted according to each provider's policy, operational needs, and legal obligations. Because the app has no account system, the digest is not connected to your real-world identity.

6Your choices and withdrawal

• You can decline the first-run privacy notice and continue playing the core game without analytics or ads.
• You can reopen privacy choices from “Privacy / PRIVACY” on the in-game pause screen.
• Withdrawal clears queued, unsent analytics and stops subsequent collection and ad requests. Restart the app as well to ensure the native ad SDK is inactive in the current process.
• Uninstall the app to remove local game data. Requests concerning SDK data can be made through the provider's official privacy channels.

7Children and teenagers

The app is not specifically directed to children under 14 and does not knowingly ask children to submit identifying information. A guardian who believes a child enabled analytics or advertising without appropriate consent should withdraw consent in the app, uninstall it, and contact us or the SDK provider through the channels below.

8Security and policy-site logs

We use reasonable measures to minimize data handling and protect app information. When you visit this policy page, its hosting and network providers may automatically process standard access logs—such as IP address, browser type, request time, and response status—for delivery, security, and troubleshooting; the analytics API gateway may create similar security logs. The first-party analytics database does not store source IP addresses. We do not use those logs to build player profiles or serve advertising.

9Updates and contact

If app features, SDKs, or information practices materially change, we will update this page and seek renewed consent when required. For app privacy requests, use the App Support or developer-contact entry on the app's App Store product page. For GroMore/Pangle SDK data questions, use the official policy pages or email union_service@bytedance.com.
