Privacy Policy

This Privacy Policy explains how Game Master ("we", "us") handles information in our mobile applications (Gomoku Master, Chess Master, Baduk Master, and future apps in the Game Master series; collectively, the "Apps"). The Apps can be used anonymously without any account or sign-up.

1. Data We Collect

We designed the Apps to collect as little as possible. All learning progress, match history, and settings are stored only on your device and are never transmitted to our servers.

• Account data: None. No sign-up is required.
• On-device data: Progress, match history, and preferences, stored locally on your device.
• Purchase data: If in-app purchases are offered, receipts are handled by Apple or Google; we never see your payment method.

2. Third-Party Services

The Apps use Google AdMob to display advertisements. AdMob may collect the following information to serve ads:

• Advertising identifiers (iOS IDFA / Android Advertising ID)
• IP address and approximate location
• Device information (model, OS version, screen size)
• Ad impressions and click events

On iOS, we request permission through Apple's App Tracking Transparency (ATT) framework before any tracking occurs. If you decline, non-personalized ads are shown instead. If an ad-free purchase is offered and activated, ads and related data collection are disabled.

• Google AdMob: Google Privacy Policy
• Ad data handling: How Google uses information from partner sites

3. Data Retention

Because we do not store user data on any server, there is no retention period on our side. On-device data stays on your device until you reset progress from in-app settings, or until you uninstall the App.

4. Your Rights

You can view, reset, or delete all on-device data at any time:

• Reset progress from within the App's settings.
• Uninstall the App to remove all local data permanently.
• Opt out of personalized advertising from your device's privacy settings.

Because we do not hold your data on our servers, we cannot access, recover, or restore it.

5. Children's Privacy

The Apps do not require an account and do not knowingly collect personal information from children. Ad delivery respects Apple's App Tracking Transparency framework and Google's family-safe ad policies.

6. Scope

This Privacy Policy applies to all apps in the Game Master series, including:

• Gomoku Master
• Chess Master
• Baduk Master
• Future apps in the Game Master series

7. Changes to This Policy

We may update this Privacy Policy from time to time. Material changes will be announced in-app or on this page at least seven days before they take effect.
