Privacy Policy
Gray World (“the App”) respects your privacy. This policy explains what data may be processed, for what purposes, with whom it may be shared, and your rights.

- Advertising (Google AdMob): To serve and measure ads, the AdMob SDK may process device-related data (e.g., device identifiers, IP address, ad-serving metadata). Depending on region and consent status, ads may be personalized or non-personalized.

3. Sharing with Third Parties
We use third-party services such as Google AdMob. These providers process data under their own privacy policies.
4. Regional Requirements
- EEA/UK (GDPR): We obtain consent for ads and cookies where required, using a Google-certified CMP. You can withdraw consent at any time.
- US State Laws: We provide opt-out options where applicable (e.g., “Do Not Sell/Share”).

5. Retention
We retain data only as long as necessary for the stated purposes or as required by law. Third-party retention follows each provider’s policy.
