ChessPadi Privacy Policy

We collect information that you provide directly to us when registering for an account, using our chess review studio, or contacting support:

• Google Account Information (OAuth): When you choose to sign in with Google, Google provides us with your primary email address, your display name, your unique Google account ID, and your public profile picture URL. We only request the standard identity scopes (openid, email, and profile).
• Chess Game Telemetry & Content: Portable Game Notation (PGN) text, FEN strings, player usernames, move notations, time controls, and opening classifications that you submit for Stockfish 18 evaluation or commentary generation.
• Payment & Billing Records: When you purchase review credits, transactions are processed by our PCI-DSS compliant payment provider, Paystack. ChessPadi does not collect, receive, or store your raw debit or credit card numbers, bank account details, or CVVs. We only receive a transaction confirmation reference, the amount paid, and the credit package selected.
• Technical & Log Data: Like most web applications, our servers automatically record basic technical data such as browser type, operating system, IP address, referral URLs, and timestamps when you interact with our pages to help troubleshoot errors and protect the platform against abuse.

We use the information we collect for strictly operational purposes:

• Authentication & Account Management: To securely sign you in via Google OAuth or email, manage your session, and grant you complimentary signup review credits.
• Game Review Library: To save, organize, and display your analyzed chess games so you can step through them anytime, share them with friends, or review past blunders.
• Grandmaster Analysis & Commentary: To pass chess move coordinates to our evaluation engine (Stockfish 18 NNUE) and AI commentary generation pipeline.
• Credit & Usage Tracking: To accurately maintain your review credit balance and deduct credits as games are analyzed.
• Security & Abuse Prevention: To detect malicious bot traffic, prevent unauthorized automated scraping, and ensure system integrity.
• Customer Support: To assist you with inquiries, transaction verifications, or bug reports.

We only share relevant information with trusted third-party service providers who help us operate our platform under strict confidentiality agreements:

We retain your personal data for as long as your account is active or as needed to provide you with your saved game review history.

We use strictly necessary first-party cookies (via NextAuth) and browser local storage solely to keep you signed in, remember your board orientation preferences (e.g. flipping the board or mute settings), and cache your active game review for smooth replay performance. We do not use third-party tracking or advertising cookies.

ChessPadi is an instructional chess platform intended for general audiences. We do not knowingly collect personal identifiable information from children under the age of 13. If you believe that a child under 13 has provided us with personal information through Google Sign-In or another method, please contact us immediately at support@chesspadi.com, and we will promptly remove such information from our systems.

We may update this Privacy Policy from time to time to reflect changes in our legal obligations or platform features. When revisions occur, we will update the "Last Updated" date at the top of this page. Your continued use of ChessPadi following any changes confirms your acceptance of the updated policy.
