  1. How We Use Your Information

We use personal information for the following purposes:

  • Account access and management: enabling Google/Kakao login, maintaining your account, preventing unauthorized access.
  • Providing game services: saving progress, delivering features, providing rankings/records, and improving gameplay experience.
  • Payments and refunds: verifying purchases, processing refunds, handling payment-related inquiries, fraud prevention.
  • Security and stability: detecting abnormal activity, preventing abuse, monitoring performance, and resolving crashes/errors.
  • Customer support: responding to questions and requests.

 

  1. Legal Basis for Processing

Where applicable, we process personal information based on:

  • Your consent (e.g., where you voluntarily provide information).
  • Performance of a contract (to provide the game services you request).
  • Legal obligations (where required by law).
  • Legitimate interests (e.g., security, fraud prevention, service improvement), balanced against your rights.

 

  1. Sharing and Disclosure

4.1 Third-party sharing

We do not sell personal information. We may share information only when necessary:

  • Service providers (e.g., hosting, customer support tools, analytics/crash tools if used) strictly to operate the service.
  • Payment providers / app stores (for purchase verification, payment processing, and refunds).
  • Legal requirements (if required by law or valid legal process).

4.2 Social login providers

Google and Kakao provide authentication services under their own privacy policies. Your social login data is handled according to their policies and your account settings.

 

  1. Data Retention

We keep personal information only for as long as necessary:

  • Account information: retained while you maintain an account; deleted upon account deletion unless retention is required for legal or security reasons.
  • Payment records: retained as required to comply with legal obligations and handle disputes/refunds.
  • Logs and security records: retained for a reasonable period to ensure security and service stability.

When the retention period ends, we delete or anonymize information in accordance with Section 7.

Depending on your jurisdiction, you may have rights to:

  • Access your personal information.
  • Correct inaccurate information.
  • Delete your information (including account deletion).
  • Restrict or object to certain processing.
  • Withdraw consent where processing is based on consent.

To request any of the above, contact us at lunar-2@nate.com. We may need to verify your identity before processing requests.

 

  1. Data Security

We take reasonable measures to protect personal information, including:

  • access control and least-privilege management,
  • security monitoring and logging,
  • encryption in transit where applicable,
  • regular maintenance and updates.

No system is 100% secure, but we work to protect your information.
