This policy applies to your personal information and data processing when using World2 App (including chat, multimodal creation, Portal, World Book, text processing scripts, media persistence/backup, and other features).

2. Information We Collect and Its Purpose

4. Data Storage and Persistence

• •Local Storage: By default, media (images/audio/video/files) are persisted to the app sandbox (Documents/Media…), enabling offline viewing and reducing duplicate downloads.

5. Third Parties and Data Transmission

• •Cloud Storage (optional): iCloud is provided by Apple and subject to Apple's Privacy Policy.
• •Not used for advertising tracking; personal data is not sold to unrelated third parties.

6. Data Security

• •Transmission uses HTTPS/TLS (secure channels provided by service providers).
• •Local data is stored in the app sandbox; it is recommended to enable password/biometric authentication for your device.
• •We continuously improve access control, anomaly monitoring, and vulnerability fixes, but cannot guarantee absolute security.

7. Your Rights

• •Access/Export: View or export your sessions and media (if backup/export tools are provided).
• •Correction/Deletion: Edit or delete sessions, media, scripts; uninstalling can delete local data.
