YOYO Private Chat stores account records, contact relationships, encrypted message payloads, reports, and subscription events required to provide the service.
Message text and user-selected image or video files are encrypted on the user's device before transmission. The service stores ciphertext and encrypted-media delivery metadata for offline delivery.
The service does not receive plaintext messages, unencrypted media files, media encryption keys, or media thumbnails. Encrypted payloads expire within 24 hours.
