Welcome to Chess Royale ("Last Piece: Royale", "单棋无双: 大逃杀", "we", "our", or "us"). We respect your privacy and are committed to protecting any information concerning users of our mobile application.
This Privacy Policy explains how information is handled when you download, install, and play Chess Royale.
Chess Royale is an offline-capable single-player strategy chess roguelike game. We do not require user accounts, registration, or logins. We do not collect, store, or transmit any personally identifiable information (PII), such as:
All game progress, high scores, survival rounds, kill records, game settings (language, vibration preferences), and match replay steps are stored strictly locally on your device via secure local storage (SharedPreferences). We do not sync or upload your game saves to any external cloud server.
Chess Royale uses Google Mobile Ads SDK (AdMob) to display optional rewarded video ads (e.g., watching a video to revive in a match or supplement in-game skill souls).
Google Mobile Ads may automatically collect and process certain non-personally identifiable technical information in accordance with Google's Privacy Policy, including:

You can manage or reset your advertising ID or opt out of personalized ads at any time through your Android device settings:
Settings -> Google -> Ads -> Reset advertising ID / Delete advertising ID.
Our game does not knowingly collect or solicit any personal information from children under the age of 13 (or under 16 in the European Economic Area). If you are a parent or guardian and believe that your child has provided us with personal information, please contact us, and we will take immediate steps to delete such data.
Because we do not maintain cloud servers or user databases for personal data, your risk of a data breach is minimized. For data handled by our third-party advertising partner (Google), industry-standard encryption protocols (HTTPS/TLS) are utilized.
We may update this Privacy Policy from time to time. Any changes will be posted within the application or on our official repository/page. Continued use of the game following any updates indicates acceptance of the revised policy.
