Privacy Policy

01. Overview & Core Privacy Commitment

At Next Move Chess (nextmovechesss.com, "we", "our", or "us"), we are committed to respecting and protecting the privacy of our visitors and users. This Privacy Policy outlines the types of information we may collect, how that information is handled, and the principles we adhere to when you visit or use our chess move calculator, board analysis, and learning guides.

Our foundational design philosophy is Privacy by Architecture. Wherever technically feasible, calculation workloads, game configurations, and interactive states are executed locally on your device rather than being transmitted to or stored on our servers.

02. Client-Side Chess Calculation (Zero Server Logging)

When you use the Next Move Chess calculator or analysis board:

• Local WebAssembly Execution: The Stockfish engine is downloaded once as a WebAssembly (WASM) binary and executes entirely within your browser's dedicated background Web Worker thread.
• No Game Position Transmission: The chess positions, piece placements, FEN (Forsyth-Edwards Notation) strings, and PGN (Portable Game Notation) moves you input are evaluated locally on your device CPU. They are not uploaded, saved, analyzed, or stored on our remote servers.
• No Account Requirement: You do not need to register, create a profile, or submit personal credentials to access full engine calculation depths and analysis features.

03. Information We May Collect

While we do not collect your chess analysis data, standard web interactions may generate minimal technical logs:

04. Local Storage & Browser Preferences

We use modern browser localStorage to remember your personal UI preferences across visits:

• Board orientation (White vs. Black perspective)
• Sound effects toggle (move audio enabled/disabled)
• Selected engine depth preferences or multi-PV line configurations

These values are stored purely on your local machine and are never transmitted to our backend. You can reset or clear these settings at any time by clearing your web browser cookies and site storage.

05. Third-Party Services & External Content

Our website may link to third-party platforms, such as open-source code repositories (GitHub), chess governing bodies (FIDE), or external documentation. We are not responsible for the privacy practices, content, or terms of third-party websites. We encourage you to review the privacy policies of any external destination you visit.

06. Children's Privacy (COPPA Compliance)

Next Move Chess is an educational and utility chess platform suitable for general audiences. We do not knowingly collect personal identifiable information from children under the age of 13 (or under 16 in certain jurisdictions). If you believe that a child has provided us with personal contact data, please contact us immediately so that we can promptly remove it.

07. User Rights (GDPR / CCPA / CPRA)

Depending on your location, you may have rights under applicable privacy regulations (such as the European Union General Data Protection Regulation or the California Consumer Privacy Act), including:

• The right to know what personal data we hold about you (e.g. past support emails).
• The right to request the deletion or correction of your communications.
• The right to opt-out of data processing (noting that we do not sell or monetize personal data).

08. Changes to This Privacy Policy

We may update this Privacy Policy periodically to reflect technological improvements, legal changes, or enhancements to Next Move Chess. Any revisions will be posted directly to this page with an updated "Effective Date".
