Privacy Policy

Three Kingdoms: Castle Guard (삼국 수성전) · Last updated: November 7, 2026

GanaHoldings Inc. (“we”, “us”, “our”) operates the mobile game Three Kingdoms: Castle Guard (the “App”). This Privacy Policy explains how we collect, use, disclose, and safeguard information when you download, access, or use the App. By using the App, you agree to this policy. If you do not agree, please do not use the App.

For questions, contact us at: drgby@ganaholdings.com

1. Scope

This policy applies to the App and to information processed in connection with the App on mobile devices. It does not apply to third-party websites, services, or applications that we do not control, even if linked from the App (for example, app store pages or ad partners’ sites).

2. Information We May Collect

The App does not require an account and does not ask for your name, email address, phone number, or contacts. Depending on how you use the App and your device settings, we may collect or receive:

2.1 Purchases (through the app stores)

The App offers one optional in-app purchase (removing ads). Apple App Store or Google Play processes the payment. We receive limited information such as the product identifier, transaction status, and purchase receipt or token provided by the store — never your payment card details.

2.2 Information collected automatically

• Device and app data: device model, operating system version, app version, language, general region (for example, country derived from IP address or store locale), and identifiers used for advertising or analytics where permitted (such as the Advertising ID on Android or the IDFA on iOS, only if you allow tracking).
• Gameplay and usage data: game progress, difficulty chosen, waves reached, session length, settings changes, and similar events used to improve balance and stability (Google Firebase Analytics).
• Diagnostics: crash reports, error logs, and performance data used to fix bugs (Google Firebase Crashlytics).

2.3 Reinforcement requests and invite codes

Reinforcement (SOS) requests store only an app-generated random ID, the wave number and the difficulty on our server (Google Firebase, Seoul region); these entries cannot be changed after 24 hours. Invite codes store the invite code (derived from the inviter's random installation ID) and the redeeming device's random installation ID with the time of redemption, kept so the inviter can receive the reward (up to 10 friends). These entries contain no name, contact details or device information; the installation ID is a random value generated by the app.

2.4 Support communications

If you email us for support, we process the content of your message and your email address to respond to you.

3. How We Use Information

• Provide, operate, and maintain the App;
• Process and verify in-app purchases and restore purchases;
• Show optional rewarded ads that you choose to watch, including personalized ads where allowed by law and your device settings;
• Analyze aggregated usage to improve difficulty balance, features, and user experience;
• Detect, prevent, and address technical issues, fraud, or abuse;
• Comply with legal obligations.

4. Advertising and Analytics

The App shows rewarded advertisements provided by Google AdMob only when you choose to watch one (for example, to continue a run or double a reward). Ad partners may use device identifiers and similar technologies to measure performance and, where permitted, to deliver interest-based advertising.

On iOS, you may see Apple’s App Tracking Transparency prompt. Your choice there controls whether your device identifier may be used for tracking across apps and websites owned by other companies. Where required by law (for example, in the European Economic Area or the United Kingdom), you will be asked for consent before personalized ads are shown.

You can also limit ad personalization through your device settings (for example, “Delete advertising ID” on Android or the tracking settings on iOS).

The services we use are provided by Google LLC: Firebase Analytics, Firebase Crashlytics, and AdMob. See Google’s Privacy Policy and how Google uses information from apps that use its services.

5. Sharing of Information

• Service providers who assist us (analytics, crash reporting, hosting), subject to contractual obligations to use data only for our purposes;
• Advertising and measurement partners (Google) as needed to show and measure ads;
• App stores (Apple, Google) as part of purchase processing and platform rules;
• Authorities when required by law, legal process, or to protect the rights, safety, or property of us, our users, or others.

We do not sell your personal information. Where laws define “sale” or “sharing” broadly (for example, certain U.S. state laws), you can opt out of ad personalization through your device settings as described above.

6. Legal Bases (where applicable)

If the GDPR or similar laws apply, we rely on: performance of a contract (to run the App and deliver purchases), legitimate interests (to secure and improve the App and measure aggregated usage), consent (where required, for example for personalized ads), and legal obligation.

7. Retention

We keep information only as long as needed for the purposes described in this policy, unless a longer period is required or permitted by law. Analytics data is retained according to the retention settings of the services above and then deleted or anonymized. Your game progress is stored on your device and is deleted when you uninstall the App or use “Reset” in the App’s settings.

8. Children’s Privacy

The App is not directed to children under the age at which parental consent is required for data collection in your region (often 13 in the U.S. or 16 in some other jurisdictions). We do not knowingly collect personal information from children in violation of applicable law. If you believe we have collected information from a child inappropriately, please contact us at drgby@ganaholdings.com.

9. Your Rights and Choices

Depending on where you live, you may have the right to access, correct, or delete your personal information, to object to or restrict certain processing, and to withdraw consent. To exercise these rights, email drgby@ganaholdings.com. We may need to verify your request before responding. You may also lodge a complaint with your local data protection authority.

10. International Transfers

Your information may be transferred to and processed in countries other than your own, including the United States, where our service providers operate. Where required, appropriate safeguards are used.

11. Security

We use reasonable administrative, technical, and organizational measures designed to protect information against unauthorized access, loss, or alteration. No method of transmission over the Internet is 100% secure.

12. Changes to This Policy

We may update this Privacy Policy from time to time. We will post the updated version at https://samguk-castle-guard.web.app/privacy.html and change the “Last updated” date above.
