Privacy Policy
This Privacy Policy explains how Azentech (“we”, “us”) collects, uses, stores and protects the personal information of users (“you”) when you access and use the online mode of the Xiangqi Master: Chinese Chess app on Android and Windows, including the versions distributed through Google Play and the Microsoft Store (the “App”).
By accessing, registering for or using the App’s online mode, you confirm that you have read, understood and agree to this entire Policy.
1. Personal data we collect
To operate the service and provide the online gaming experience, we collect the following categories of data:
- Device identifier: A random identifier generated by the App on first launch and stored on your device (Android phone/tablet or Windows PC), used to create and maintain your guest account. We do not collect your IMEI, phone number, advertising ID (Google Advertising ID or Windows advertising ID) or hardware serial numbers.
- Account information:
- Guest account: A random display name generated by the system.
- Google account (optional): If you choose to sign in with Google (on Windows, Google’s sign-in page opens in your web browser) or with Google Play Games Services (Android only), we collect your Google account ID, display name and email address to link your game data. We do not collect, store or access your Google password.
- Game & ranking data: ELO rating, rank, win/loss/draw history and game results. Moves are processed in real time on the server to validate them; the detailed move history is not stored after a game ends.
- Interactive content (chat messages): Text you send during a game (available to signed-in accounts). Messages are relayed instantly to the players at your table and are not stored long-term.
- Technical data & system logs: IP address, connection times, crash logs and system requests, used for security, operations and cheat prevention.
Note: The App does not access your contacts, location, photo library, microphone, camera, SMS or payment data, and on Windows it does not read your personal files. Display, sound and offline difficulty settings are stored entirely on your device. Games against the computer run fully offline: the AI engine runs on your device and no data about these games is sent to us.
2. Purposes of processing
The personal data we collect is used only for the following purposes:
- Creating, authenticating and maintaining user accounts; matchmaking and validating games.
- Calculating and updating ELO ratings and displaying public leaderboards.
- Operating, maintaining, troubleshooting and optimizing the App’s performance.
- Detecting and preventing cheating, unauthorized interference or violations of the game rules.
- Complying with legal obligations at the request of competent state authorities.
We do not sell, rent or share your personal information with third parties for advertising or behavioral marketing purposes.
3. Publicly displayed information
When you play online, your display name and ELO rating are publicly visible in the lobby, at game tables and on the leaderboard.
To protect your privacy, we recommend that you do not use your real full name, phone number, address or any other sensitive personal information as your display name or share it via in-game chat. We are not responsible for risks arising from personal information you voluntarily disclose while interacting with other players.
4. Sharing and transfer of data to third parties
We share only the minimum data necessary with trusted service providers to operate the App, including:
- Infrastructure & server providers: To store account data and process game sessions.
- Google LLC: Provides account authentication (Google Sign-In on Android and Windows; Google Play Games Services on Android).
- App stores — Google Play (Google LLC) and Microsoft Store (Microsoft Corporation): Distribute the App and handle downloads and updates under their own privacy policies. We only receive aggregated, non-identifying statistics from them (such as install counts and crash reports).
- Auxiliary technology providers: Help automatically moderate chat messages to keep conversations healthy (data is sent anonymously, without personally identifying information).
These third parties are bound by confidentiality obligations and may only process data within the scope of the services they provide. Apart from this, we disclose data only upon a written request from a state regulatory or law enforcement authority as required by law.
5. Data retention
- Account & ranking data: Kept for as long as your account is active, until you request account deletion.
- Technical logs: Automatically deleted or overwritten periodically (usually within 14 to 30 days depending on the log type).
- Chat messages & moves: Processed in real time and not stored long-term on our servers.
6. Data security
We apply appropriate technical measures (such as HTTPS/WSS encrypted connections and strict access control for administrative systems) to protect personal data from unauthorized access, disclosure or destruction.
However, no method of transmission over the Internet or electronic storage is 100% secure. In the event of a security incident affecting personal data, we will remediate it and notify users and the relevant authorities as required by law.
7. Your rights and data deletion requests
Under Vietnam’s Decree 13/2023/ND-CP on personal data protection, you have full rights over your personal data (including the rights to be informed, access, rectify, object to processing and request deletion).
To exercise your right to delete your account and all personal data, please:
- Send an email from your registered email address (or your contact email) to: [email protected].
- Use the subject line: “Xiangqi Master: Chinese Chess account deletion request”.
- Include your in-game display name and your identifier/sign-in email (if any).
We will verify and process your request within 30 days. Note: once your account is deleted, all ELO, ranking and related history data is permanently destroyed and cannot be recovered.
8. Children’s privacy
The App does not knowingly collect or process personal data of children under 13 without the consent of a parent or guardian. If you are a parent or guardian and discover that your child has provided us with personal data, please contact us by email so we can delete it promptly.
9. Changes to this Policy
We may update this Privacy Policy from time to time to reflect changes to the App or applicable laws. Updates take effect as soon as they are published. Your continued use of the App after the Policy is updated means you accept those changes.
