OnlyU+

Most messaging apps promise privacy. 4UONLY delivers it. No servers. No history. No traces — on either side. When the conversation ends, it's gone. Completely.

4UONLY is a private messenger built for exactly one relationship - the one that matters most.

Unlike group chats and social feeds, 4UONLY connects you with a single trusted person through end-to-end peer-to-peer technology. No servers store your messages. No algorithms read your words.

HOW IT WORKS

Pair once with one person using an invite code or QR code. Your connection is direct, encrypted, and private by design.

Messages travel peer-to-peer via WebRTC - the same technology used for secure video calls - so they never touch a central server. When both of you agree, a message can be saved locally. Otherwise, it disappears when you close the app.

FEATURES

• One-to-one pairing: connect with exactly one trusted person
• P2P messaging: messages never stored on any server
• Messages leave no trace: nothing is saved locally unless your partner explicitly agrees
• Auto-clear on close: every message on both devices is permanently deleted each time the app closes
• Change your name anytime: update your display name whenever you like; your partner sees the change instantly. Can also change your partner's display name.
• Unpair in one tap: break the connection at any moment; all conversation history is deleted immediately with no trace left behind
• Encrypted channel: your conversation channel is always secured end-to-end
• Voice and video calls: clear, private calls directly between devices
• File sharing: send photos and PDFs up to 5 MB
• Face ID / Touch ID lock: biometric protection to ensure only you can use the app
• Screen capture protection: content is hidden when the screen is being captured or recorded

PRIVACY FIRST

4UONLY collects no personal data, not even your IP address. No account required. No phone number. No email. Your pairing information lives only in your device's secure Keychain and never leaves your phone.
