Privacy Policy

1. Information We Collect and Why

We collect information from you, automatically when you use the Services, and from providers you choose to use, such as Apple and Google.

• Account and contact information. This may include your email address, sign-in provider identifier, display name, coaching preferences, waitlist information, the legal version and server time of your acceptance, and messages you send us. We use it to create and secure your account, apply your account choices, provide support, and send requested service communications. Public leaderboards may show your display name, rank, and progression metric.
• Gameplay and coaching information. This includes games, moves, dice, positions, outcomes, progress, achievements, coaching feedback, lesson history, and related game identifiers. We use it to run and restore games, provide analysis and coaching, track progress, and improve gameplay.
• Device and usage information. This may include your IP address, device or installation identifier, operating system, app and engine versions, locale, essential browser storage, request logs, crash information, and performance data. We use it to operate, secure, and troubleshoot the Services and to prevent fraud, cheating, and abuse.
• Purchase information. Apple or Google may provide us with product, transaction, subscription, refund, revocation, and entitlement information. We do not receive your full payment-card details or your Apple or Google account credentials.

On Apple Vision Pro, spatial input is processed on the device to let you interact with the game. We do not receive or store raw hand-tracking, eye-tracking, room-mapping, camera, depth, or facial-mapping data. Gameplay actions created from those interactions, such as moving a checker, are processed like gameplay actions from the mobile app.

Where applicable law requires a legal basis, we process information as necessary to provide the Services under our agreement with you, for our legitimate interests in operating and protecting the Services, with your consent for optional processing, or to comply with law.

2. Operational Data and Optional Analytics

GGammon uses account, installation, and session identifiers; gameplay events; request logs; purchase and entitlement information; and limited device and app details to sign you in, run and restore games, sync progress, validate purchases, secure the Services, prevent fraud and cheating, diagnose failures, and provide support. This operational processing is necessary to provide the online functions you request or for our legitimate interests in security and reliability. It cannot be disabled while you use the affected functions.

If we offer analytics that is not necessary to provide or secure the Services, we will request prior consent where required and provide a way to withdraw it. We do not treat an app-store permission, a preselected setting, or continued use as consent. Some app versions store a local telemetry preference; that preference does not control the operational processing described above, and we do not rely on it as consent for nonessential analytics. Refusing or withdrawing optional-analytics consent will not affect core gameplay.

3. When We Share Information

We may disclose information as reasonably necessary to:

• operate the Services through hosting, database, security, monitoring, support, and email providers;
• complete sign-in or purchases through Apple, Google, or another provider you choose;
• deliver and measure mobile ads through Google and participating advertising partners when advertising is enabled, as described below;
• comply with law, protect rights or safety, or investigate fraud and abuse; or
• complete a merger, financing, reorganization, or sale of the business, subject to appropriate confidentiality protections.

We do not rent personal information or sell it for money.

4. Advertising and Tracking

The GGammon website and Apple Vision Pro app do not serve ads. A GGammon Mobile release configured for advertising may use Google Mobile Ads and Google's consent tools. If enabled, Google and its advertising partners may process IP address, approximate location, device and app identifiers, ad interactions, consent choices, and diagnostics for ad delivery, measurement, security, and permitted personalization.

Mobile requests ads only after the applicable consent tooling permits it. Where required, you can review or change advertising choices through the app's Privacy Options. We do not sell personal information for money. Some laws may treat personalized-ad disclosures as a sale, sharing, or targeted advertising; where they apply, we provide the required choice.

5. Retention and Deletion

We keep personal information only as long as reasonably necessary for the purposes described above. Account, gameplay, progress, and coaching records are generally kept while your account is active. Waitlist and support information is kept while needed to provide the requested communication or support. Purchase, security, fraud-prevention, dispute, accounting, and legal records may be kept longer where reasonably necessary or required by law. We may de-identify information that no longer needs to be linked to you.

You may start a support-assisted account-deletion request at https://ggammon.ai/account-deletion. After we verify control of the account, we will handle eligible account information as required by applicable law and explain any information we retain and why.

Deleting your GGammon account does not cancel an Apple or Google subscription. You must manage or cancel an active subscription through the applicable app store.
