1. Acceptance of Terms
By downloading, installing, accessing, or playing Chess Master Arena ("the App"), you agree to be bound by these Terms of Service. If you do not agree to these Terms, you must immediately uninstall and cease using the App.
2. Eligibility and Account Registration
You must be at least 13 years of age (or the minimum legal age required in your country) to create an account. You agree to provide accurate, current, and complete information during registration and to keep your credentials confidential. You are solely responsible for all activities conducted through your account.
3. Fair Play and Prohibited Cheating Policy
Chess Master Arena is committed to competitive integrity. When playing online friend matches or competitive multiplayer games, you strictly agree NOT to:
- Prohibited Engine Assistance: Consult external chess engines (such as Stockfish, Leela Chess Zero, Komodo), algorithmic solver bots, opening books, or endgame tablebases during a live match.
- Outside Assistance: Accept move recommendations from third-party players, grandmasters, or external software during live games.
- Rating Manipulation: Deliberately forfeit games to inflate or deflate ratings (sandbagging or rating boosting), or collude with opponents.
- Griefing and Clock Stalling: Intentionally disconnect, abandon boards, or stall clocks indefinitely to force opponent resignations.
We reserve the right to review match records, flag engine correlation anomalies, ban accounts, reset ratings, and terminate access for any player violating our Fair Play Policy.
4. Online Multiplayer, Heartbeats & Disconnections
Multiplayer games are facilitated using room codes and Firebase Cloud Firestore. To accommodate transient wireless drops, our system implements a five (5) minute disconnection grace period. If a player disconnects, their opponent is notified, and a countdown timer initiates. If the disconnected player fails to reconnect before the grace period expires, the remaining player may claim victory on abandonment. We cannot guarantee uninterrupted server connectivity or compensate for cellular drops.
5. In-Game Ratings and Leaderboards
Ratings (Rapid, Blitz, Bullet Elo) are calculated mathematically based on standard FIDE Elo formulas with K = 32. Ratings represent an approximate measure of relative chess performance within the App and possess no commercial, monetary, or transferable value. We reserve the right to recalculate or reset ratings in cases of technical error, server rollback, or cheating sanctions.
6. Advertising and Monetization
The App is offered free of charge supported by advertisements served by Google AdMob. You agree not to block, tamper with, or artificially simulate ad impressions or clicks. We may provide optional in-app purchases or ad-free subscriptions in future versions, which will be governed by Google Play Billing terms.
7. Intellectual Property Rights
All intellectual property rights in Chess Master Arena — including source code, UI designs, graphics, audio, animations, and branding — are owned by Digital Leads.
