This page explains what information CheckmateLeague collects, how it is used, how it may be shared, and how we work to protect your data when you use the platform.
“CheckmateLeague,” “we,” “us,” and “our” refer to CheckmateLeague and its related website, gameplay services, tournaments, leagues, training features, creator tools, and support services.
We use your information to:
CheckmateLeague uses USDC on the Base network for supported on-chain payment flows and rewards-related payouts.
We may store wallet addresses, transaction hashes, payment status information, amounts, creator code usage, reward funding logs, reward payout logs, and withdraw request records needed to operate the platform and investigate disputes or abuse.
We do not store private keys for your personal wallet, and we do not store traditional credit card or bank account details as part of the platform flows described in these pages.
To protect the platform, we may review gameplay records, account activity, match behavior, timing patterns, device signals, IP data, training or analysis-related activity, and other integrity indicators.
This monitoring helps us detect cheating, multi-accounting, collusion, fraud, payment abuse, exploit abuse, and other conduct that could harm the platform or its players.
We use essential cookies or similar local technologies to maintain sessions, remember basic preferences, and support platform security and functionality.
We may also use limited technical logging or local storage features required for gameplay, account continuity, or performance. We do not state that we use advertising cookies on these pages.
We do not sell your personal information.
We may share information with service providers and infrastructure partners that help us operate the platform, such as hosting, authentication, cloud database, analytics, wallet or blockchain infrastructure, anti-fraud tooling, communications providers, and customer support tools.
We may also share information when reasonably necessary to investigate fraud, enforce platform rules, respond to legal requests, or protect users, the platform, or our rights.
We use technical, administrative, and platform-level measures designed to help protect user data, including HTTPS, authentication controls, server-side checks, rate limiting, and managed infrastructure tools.
No system is perfectly secure, so we cannot guarantee absolute security. You are also responsible for keeping your email, password, device, and wallet access secure.
We keep information for as long as reasonably necessary to operate the platform, maintain records, resolve disputes, investigate abuse, comply with law, and enforce our policies.
Some records may remain in logs, backups, payment records, anti-fraud records, or legal/compliance records even after an account is closed or deleted.
Depending on your location, you may have the right to request access to your data, correction of inaccurate data, or deletion of certain account information.
Some information may need to be retained for security, fraud prevention, payment records, event integrity, or legal obligations.
CheckmateLeague is intended for users who are 18 years of age or older. We do not intend to knowingly allow underage use of restricted platform features.
We may update this Privacy Policy from time to time. When we do, we will post the updated version on this page and revise the effective date.
