Privacy Policy

Last Updated: October 2026 • Grand Chess 3D

Welcome to Grand Chess 3D ("the Game", "we", "our", or "us"). We are committed to protecting your privacy and providing a safe, enjoyable gaming experience. This Privacy Policy explains what information is collected, how it is used, and how your privacy is protected when you play Grand Chess 3D across web, mobile browsers, and native applications.

1. Information We Collect

We believe in data minimization. Grand Chess 3D is engineered to function with zero mandatory account registration or invasive tracking:

Local Gameplay Data (Stored Locally on Your Device): Your game settings, preferred board and piece themes, sound preferences, Elo rating, match history, earned virtual coins, unlocked passes, and achievements are stored strictly on your local device using standard browser localStorage. This data never leaves your device unless you explicitly export it.
Peer-to-Peer (P2P) Multiplayer Data: When playing multiplayer via local hotspot, QR code, or direct room code, peer connections are established directly between devices using WebRTC. Game moves are transmitted directly between players. We do not inspect, log, or store your in-game moves or chat emotes on central servers.
Technical & Diagnostics Information: Standard, non-personally identifiable diagnostic data (such as browser type, operating system, screen dimensions, and crash logs) may be processed transiently to optimize 3D graphics rendering and ensure smooth performance.

2. Advertising & Third-Party Services

Grand Chess 3D may display third-party advertisements (such as Google AdMob or Google AdSense) and rewarded video ads that grant optional in-game rewards (e.g., bonus undos or hints):

Third-party ad networks may use device identifiers (such as Google Advertising ID) or cookies to serve contextual or personalized advertisements in accordance with applicable platform policies and user consent settings.
Players may opt out of personalized ads at any time through their device operating system settings (e.g., Android Settings > Google > Ads > Opt out of Ads Personalization).
Purchasing an optional VIP No-Ads Pass or Club Master Pass completely deactivates third-party banner and interstitial advertisements permanently.

3. In-App Purchases & Payments

All in-app purchases (such as Coin Packs or VIP Passes) are processed securely through certified platform payment providers (such as Google Play Billing or PCI-DSS certified payment gateways). We never collect, process, or store your credit card, debit card, bank account, or UPI payment credentials on our servers.

4. Matchmaking & Gameplay Features

      Simulated Participation Disclosure: To ensure prompt matchmaking, minimize wait times, and guarantee continuous gameplay across all hours and network conditions, players may occasionally be paired with automated opponents or simulated participants designed to emulate human play styles and timing.
    

5. Children’s Privacy (COPPA & Family Policy Compliance)

Grand Chess 3D is a general-audience strategy game suitable for all ages. We do not knowingly collect, request, or solicit personally identifiable information (PII) from children under the age of 13 (or under the age of 16 in the European Union). If you believe a child has provided us with personal information, please contact us immediately so we can remove it.

6. Data Security & Retention

Because gameplay progress and virtual currency balances are retained locally on your device, you have full control over your data. You can erase all game data at any time by clearing your browser cache/storage or uninstalling the application.

7. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect operational, legal, or regulatory requirements. The updated policy will always be published on this page with an updated "Last Updated" date.
