About this app

YOYO Private Chat is a focused encrypted messenger for people who want simple private text conversations without social noise.

Open a contact, send a message, and keep the conversation clean. Messages are encrypted before leaving your device, and normal chat messages use read-once behavior: after a conversation is opened, they disappear on your chosen timer. Unopened messages expire after 24 hours.

Why it stands out:
- One-to-one encrypted text chat
- Read-once messages by default
- App password lock for local privacy
- Username contacts with local notes
- Block, unblock, report, recall, and delete chat history
- Privacy-minded push notifications
- English, Japanese, and Chinese interface

Pro unlocks more contact capacity. Encryption strength is the same for free and Pro users.

YOYO Private Chat intentionally stays simple. It does not include group chat, public people search, social feeds, images, files, voice, video, read receipts, typing status, or online status.

Security note: YOYO Private Chat is designed to keep plaintext message bodies off the server. No app can promise absolute security, so keep your device and password protected.

What’s new

Major update: adds end-to-end encrypted voice and video calls between contacts. Call invitations and signaling are encrypted, with mute, speaker, camera controls, and camera switching. Also includes stability and privacy improvements.
