For jurisdictions that require a legal basis (such as GDPR/UK GDPR), we process personal data based on:

Performance of a contract (delivering app functionality and purchase entitlements).
Legitimate interests (security, analytics, fraud prevention, and operational reliability).
Consent (where required for targeted advertising, non-essential tracking, or certain local law requirements).
Legal obligations (compliance, accounting, tax, and law enforcement response duties).

5. Advertising, Analytics, and Monetization

Our Services may integrate third-party advertising and analytics SDKs. These partners may process device-level identifiers and event data in accordance with their own privacy policies and applicable law.

Ads may be contextual or personalized depending on jurisdiction, user settings, and platform permissions.
Subscriptions and in-app purchases are processed via official store billing systems.

Payment, app store, and billing partners for transaction execution and entitlement management.
Authorities or legal entities when required by law or to protect legal rights and user safety.

We do not sell personal information in exchange for direct monetary payment.

7. International Data Transfers

Because we publish globally, data may be processed in jurisdictions outside your country. Where required, we implement safeguards such as contractual protections and transfer mechanisms recognized by applicable law.

8. Data Retention

We retain personal data only as long as needed for the purposes described in this policy, including legal, accounting, dispute resolution, and platform compliance requirements. Retention periods vary by data type, operational need, and local legal obligations.

9. Security Measures

We apply reasonable technical and organizational controls to protect personal information, including access control, environment security, and monitoring mechanisms. No internet transmission or storage system is 100% secure.

10. Children and Age-Sensitive Use

Our Services are designed and operated in consideration of age-related policy requirements. Where legally required, we apply age-gating, content controls, and consent pathways. If you believe a child has provided personal data in violation of law, contact us for review and remediation.
