Privacy Policy

We may collect the following information to operate and improve the Game:

• Device information: device model, OS version, language settings, screen resolution, advertising identifiers (IDFA / AAID), and similar technical data.
• Gameplay information: play time, waves reached, scores, in-game actions, and crash reports.

• Contact information: name, email address, and message contents when you reach out to support.
• Cookies and similar technologies: third-party services may use cookies or identifiers for advertising and analytics.

We use collected information only for the following purposes:

• Providing, maintaining, protecting, and improving the Game
• Investigating and fixing bugs and crashes
• Optimizing ad delivery and measuring ad performance
• Announcing new features and events
• Preventing fraud and violations of the terms of service
• Responding to and verifying support inquiries
• Aggregated analytics that do not identify individuals

The Game uses certain third-party services to deliver and improve the experience. These services handle information under their own privacy policies.

• Apple App Store / Google Play (distribution and billing)
• Analytics providers such as Google Analytics for Firebase
• Ad networks such as Google AdMob and Unity Ads
• Crash reporting services such as Firebase Crashlytics
• Cloud hosting providers

To opt out of personalized advertising, use your device's OS-level settings (e.g. "Limit Ad Tracking," "Reset Advertising ID").

The Game is not designed for or directed at children under the age of 13 (under COPPA in the United States) or the equivalent minimum age under applicable law in other regions.

If you are a parent or guardian and believe your child has provided us with personal information, please contact us at the address below. We will verify and promptly delete the information.

We do not sell or share your personal information with third parties without your consent, except in the following cases:

• When required by law or legal process
• When necessary to protect a person's life, body, or property and consent is impractical
• When sharing with service providers acting on our behalf, under appropriate confidentiality and security obligations

We retain information for as long as reasonably necessary for the purposes described in this policy. Once data is no longer needed, or once the legally required retention period ends, we delete or anonymize it.

We use industry-standard measures, including encrypted transport and access controls, to protect information from loss, alteration, and unauthorized access. We also supervise any third-party processors that handle data on our behalf.

The Game does not require an account or login. Gameplay progress is stored only on your device, and you can fully erase it yourself at any time by uninstalling the app.

For information you submit when contacting support (name, email, message contents) and for technical identifiers used in analytics or crash reports, you may request access, correction, deletion, or suspension of use by contacting us using the details below. After verifying your identity, we will respond promptly.

Some third-party services we use may operate servers outside your country of residence (including outside Japan). These services process information under their respective privacy policies and applicable law.

We may revise this policy from time to time. Material changes will be announced inside the Game or on this page. By continuing to use the Game after the changes take effect, you are deemed to have agreed to the updated policy.
