Privacy Policy

This policy explains how Chess Coach handles information when you use our browser extension and related services.

Chess Coach browser extensionLast updated: 9 November 2026

1. Who we are

Chess Coach is a browser extension that helps users review completed chess games, understand mistakes, practice chess puzzles, and use AI-assisted coaching features.

Service operator: Chess Coach, operated by an independent developer.

Privacy contact: wdfwdfwdfwdf0@gmail.com.

2. Information we handle

Depending on the features you choose to use, Chess Coach may handle the following categories of information:

  • Account information: information used to create or authenticate an account, such as an email address and authentication identifiers, if account features are enabled.
  • Chess information: game records (including PGN or move data), positions, analysis results, puzzles, and mistake-notebook entries that you submit or choose to save.
  • Extension settings: preferences and locally stored settings needed to operate the extension.
  • Subscription information: subscription status, entitlement, and transaction references needed to provide paid features. Payment card details should be handled by the payment processor, not stored by the extension, where that is how your payment integration works.
  • Technical information: limited diagnostic, request, or error information generated when the extension communicates with its services.
  • Support messages: information you choose to provide when contacting support.

Chess Coach does not need access to unrelated browsing history to provide its core chess features. Do not submit sensitive personal information in chess-game fields or support messages.

3. How information is used

Information is used only as needed to:

  • provide game import, review, analysis, puzzles, and coaching features;
  • authenticate users and maintain account sessions;
  • save and synchronize settings, game-related records, and learning history when those features are enabled;
  • check subscription entitlements and provide paid features;
  • maintain, secure, troubleshoot, and improve the service; and
  • respond to user support requests and comply with applicable legal obligations.

If an AI coaching or analysis feature is used, the relevant prompt, chess position, moves, or other content needed to answer your request may be sent to the AI service configured by the operator. [IDENTIFY THE AI PROVIDER(S) AND CONFIRM EXACTLY WHAT IS SENT BEFORE PUBLISHING.]

4. Service providers and third-party services

Chess Coach may rely on third-party services to operate its features. Based on the current extension configuration, these may include:

  • Supabase: may provide authentication, database, or related backend services.
  • Cloudflare: may process requests through backend or infrastructure services.
  • Lichess: may provide chess-game or chess-related data when you use a Lichess integration.
  • AI service provider(s): may process chess positions or prompts to deliver AI coaching, if you use those features.
  • Payment provider: [INSERT THE ACTUAL PROVIDER, e.g. Stripe or PayPal, if applicable]. It may process payment details and provide subscription status or transaction references.

These providers process information under their own terms and privacy policies and, where applicable, our instructions and agreements. We do not sell personal information. We do not share information with third parties for their independent advertising purposes.

Only list providers that are actually used in the released version. Update this section if your service providers or data flows change.

5. Storage, security, and retention

Some settings or extension data may be stored locally using Chrome extension storage. Account-related or synchronized information may be stored by the backend providers used by Chess Coach.

We retain information only for as long as reasonably necessary to provide the service, maintain account and subscription records, resolve disputes, enforce agreements, and meet legal requirements. [ADD YOUR ACTUAL RETENTION PERIODS AND DELETION RULES BEFORE PUBLISHING.]

We use reasonable technical and organizational safeguards designed to protect information. No method of transmission or storage is completely secure.

6. Your choices and privacy rights

You can choose whether to use optional features, connect third-party chess services, or grant optional browser permissions. You can manage or revoke extension permissions through Chrome settings and uninstall the extension at any time.

You may request access to, correction of, or deletion of personal information associated with your account, subject to applicable law and legitimate record-keeping requirements. To make a request, contact us using the email in the Contact section. We may need to verify your identity before acting on a request.

Uninstalling the extension may remove locally stored extension data, but it does not necessarily delete information already stored on remote servers. Contact us to request deletion of server-side account data.

7. Security

We take reasonable steps to protect information against unauthorized access, loss, misuse, or alteration. You are responsible for keeping your account credentials confidential and using a secure device and browser.

8. Children’s privacy

Chess Coach is not designed to knowingly collect personal information from children in violation of applicable law. If you believe a child has provided personal information improperly, contact us so we can review the request and take appropriate action.

9. Changes to this policy

We may update this Privacy Policy when our features, data practices, or legal obligations change. The updated version will be published at this URL with a revised “Last updated” date. Your continued use of the service after an update means you have had the opportunity to review the revised policy.
