Privacy Policy

Effective date: July 25, 2026

This policy applies to the mobile game Prism Defense (the "Service"), provided by Dongmin Yu (the "Developer").

1. Information the Developer collects

None. The Service requires no account, the Developer operates no server, and the Developer does not collect, store, or sell any personal information.

2. Information stored only on your device

The following is stored only on your device and never leaves it:

• Game records (best wave, kills, daily challenge records)
• Settings (sound/music mute, language, tower strategy modes, and similar)

Uninstalling the app deletes this information.

3. Advertising and third-party services (Google AdMob)

Release builds of the Service may show ads (rewarded ads, interstitials) through Google AdMob. To serve ads, Google may collect and process information such as:

• Advertising identifiers (Android Advertising ID, iOS IDFA)
• IP address and coarse location
• Device information (model, OS version, and similar)
• Ad-interaction data (impressions, clicks)

For details on Google's processing, see:

• Google Privacy Policy
• Google ad technology providers

4. Ad consent

• In regulated regions (EEA, UK, and similar), the Google UMP (User Messaging Platform) consent form appears on first launch, and you can choose whether to receive personalized ads.
• On iOS, the App Tracking Transparency (ATT) prompt may be requested; if you decline, only non-personalized ads are served.
• Gameplay is never restricted by your consent choice. Consent gates ads, not play.
• You can change or withdraw consent at any time via the app's privacy options menu (where provided) or your device settings (resetting or deleting the advertising ID, iOS tracking settings).

5. Retention

The Developer holds no personal information and therefore has no retention period. Google's retention of information processed for ad serving follows Google's policies.

6. Children

The Service is not directed at children, and the Developer does not knowingly collect personal information from children.

7. Your rights

You can reset your advertising identifier or limit personalized ads at any time in your device settings, and you can direct any privacy inquiry to the contact below.

8. Changes to this policy

If this policy changes, the revised policy and its effective date will be posted on this page.
