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. Optional AI Coaching

GGammon uses BGBlitz to produce deterministic backgammon analysis. If you choose AI coaching, we may send a coaching packet to OpenAI so it can turn that analysis into a short explanation or end-of-game lesson.

The packet may contain the relevant board position and moves, analyzer facts, your coaching-language choice, and your account coaching history, such as prior lessons, feedback, concepts, and progress or mistake observations. End-of-game lessons may use the coaching history available for your account. We do not intentionally include your name, email address, payment information, or raw Apple Vision Pro spatial data.

After sign-in, if your account has no current AI-coaching choice, GGammon Mobile and GGammon for Apple Vision Pro ask you to choose before any packet is sent. We store the choice on your account, so a current choice applies across your devices. We may ask again if the provider, purpose, or information sent changes materially, or if renewed consent is required by law.

You can change or withdraw your choice in the app's account settings. Declining does not prevent you from playing or using BGBlitz analysis; it disables AI-written explanations and lessons. Withdrawing permission stops future coaching packets from being sent to OpenAI after the change takes effect; a request already in progress may finish. Withdrawal does not undo processing that already occurred.

We configure OpenAI requests so generated responses are not stored for later retrieval through the API. This does not mean immediate deletion: under OpenAI's standard API controls, prompt and response content may be retained in abuse-monitoring logs for up to 30 days, or longer if required by law or reasonably necessary to protect OpenAI's services or third parties.

AI-written coaching may be incomplete or incorrect and is provided only as game instruction.

4. Children

GGammon's account service is intended for people age 16 and older, and our Terms require account users to be at least 16. We do not offer a parent or guardian authorization flow for younger users. If we learn that an account belongs to someone under 16, we will take reasonable steps to close the account and delete associated personal information, subject to limited legal retention requirements. If you believe someone under 16 has used GGammon, contact us at contact@vrgammon.com.

5. 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;
• provide AI coaching through OpenAI, but only after the permission described above;
• 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.

6. 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.

7. 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.

8. Your Choices and Privacy Rights

Depending on where you live, you may have the right to request access to, correction of, deletion of, or a copy of your personal information; request portability; object to or restrict certain processing; withdraw consent; or appeal a denied request. You may also have the right to complain to a privacy regulator or use an authorized agent. We will not discriminate against you for exercising a privacy right.

To make a request, email contact@vrgammon.com. We may need to verify your identity or your control of the relevant account.

You may unsubscribe from non-essential email using the instructions in the message. We may still send service, security, purchase, or account notices when necessary.

9. International Processing and Security

We and our service providers may process information in the United States and other countries. Where required, we use legally recognized safeguards for international transfers.

We use reasonable administrative, technical, and organizational measures designed to protect personal information. No transmission or storage system can be guaranteed completely secure.

10. Changes and Contact

We may update this Policy as the Services or legal requirements change. We will post the updated version, revise the date above, and provide additional notice or request renewed consent when required.
