The Đoán Chữ Vui application (“the app”) respects your privacy.

This Privacy Policy explains what data may be collected when you use the app and how that data is processed by third-party services.

1. Data Collected (Non-Personal and Not Linked to the User)

The app does not collect or process any personal data, including:

• Name, email address, phone number
• User accounts or login credentials
• Photos, videos, audio recordings, camera, or microphone access
• Contacts
• Financial or payment information
• Precise location (GPS)
• The advertising identifier (IDFA)

However, because the app displays non-personalized ads using third-party advertising SDKs (such as Unity Ads), certain non-personal data may be collected automatically by those SDKs. This data is not linked to your identity and cannot identify you as an individual.

This may include:

1.1. Location (Coarse Location)

• Approximate location inferred from the device’s IP address
• Not precise GPS or exact real-time location

1.2. Identifiers (Device ID — not IDFA)

• IDFV or internal SDK identifiers
