Privacy

What we collect

• Account and authentication identifiers when you sign in.
• Chess game data you submit, import, or connect, including PGN content and game identifiers from supported chess services.
• Analysis results, coaching preferences, training progress, repertoire information, and other product state needed to provide personalized coaching.
• Support questions, ticket messages, and related service context when you use the Help Center.
• Subscription and entitlement status needed to provide Free or Pro access. Payment processing is handled by Stripe; MyChessCoach does not need your full payment-card number to operate the subscription.
• Operational logs and security information needed to diagnose failures, protect accounts, enforce entitlements, and operate the service.

Aggregate launch analytics

MyChessCoach keeps first-party daily aggregate counts for a small allowlist of launch-funnel events such as landing and pricing views, authentication, pricing intent, successful game import and analysis, checkout start, confirmed Pro activation, failed payments, and confirmed support requests. These launch counters contain only the UTC day, event name, and total count. They do not store a user or profile ID, session identifier, IP address, referrer, user agent, cookie value, or arbitrary event metadata.

How we use data

Data is used to authenticate members, import and analyze games, generate coaching and training features, maintain subscriptions, provide support, prevent abuse, diagnose failures, measure aggregate launch-funnel performance, and improve service reliability.

Data purposes by category

• Email and authentication identifiers: sign-in, account security, and account communication.
• PGNs, game records, imports, and chess-provider identities: requested game import, analysis, coaching, and display.
• Analysis, coaching, repertoire, and training state: personalized training features and continuity of service.
• Support questions and ticket context: answer questions, investigate issues, and provide confirmed support escalation.
• Subscription and billing state: entitlements, billing support, fraud prevention, and service administration.
• Operational and security logs: reliability, abuse prevention, incident response, and service security.

AI and third-party processing

Some Pro coaching features use configured third-party AI providers. When such a feature is used, relevant game, analysis, repertoire, or coaching context may be sent to those providers to produce the requested result. Free and anonymous product AI is restricted by the current MyChessCoach entitlement policy. Stockfish chess-engine computation is separate from paid language-model processing.

Help Center questions are answered from curated guidance first. Eligible Pro users may receive a grounded AI fallback when curated guidance is insufficient. A support ticket is created only after the user confirms. When a confirmed ticket is created, the relevant question, conversation context, account identifier, and email where available may be transmitted to the configured Bookiji support system. MyChessCoach also relies on service providers for hosting, authentication, database infrastructure, payment processing, monitoring, and related operations. Some processing may occur outside Quebec or Canada; we do not claim Canadian-only storage. We do not sell personal data.

Retention and deletion

Different categories are retained only as needed for the purposes described above, account security, service reliability, requested history, dispute handling, and legal obligations. Bookiji maintains internal retention and destruction practices for accounts, game and analysis data, support records, billing metadata, operational logs, security events, and backups. Exact periods may vary by category and are available through the privacy-request process where applicable. If you want help accessing, correcting, exporting, or deleting account-related data, contact MyChessCoach through Support or the Help Center so the request can be verified and handled against the correct account. We may need to retain limited information where required for security, fraud prevention, legal obligations, or dispute resolution.

Applicable law may limit a request or require retention of some information.
