Wyfari vs Md Preview

Wyfari is a peer-to-peer encrypted messenger that never touches the internet. No servers. No cloud. No accounts. Messages travel directly between devices and nowhere else — even if you're connected to WiFi. And it's completely free. Nothing is ever uploaded, transmitted, or stored anywhere other than the two devices in the conversation. Not metadata. Not analytics. Not anything. There is no server. There is no backend. There is nothing to hack, subpoena, or leak. HOW IT WORKS Scan a QR code to pair with someone nearby. That's it. No sign-up, no phone number, no email. Messages are encrypted end-to-end with X25519 key exchange and AES-256-GCM, transmitted directly between devices over Bluetooth and WiFi Direct. FEATURES Completely offline — no internet or cell service needed Up to 100m range over WiFi Direct Offline message queuing — type while disconnected, delivers on reconnect Auto-reconnect when back in range Typing indicators and read receipts All data stored locally on your device only Clear all data to wipe everything instantly Wyfari works in airplane mode, underground, off-grid, or sitting right next to your home router. It doesn't matter. The internet is never used. Period.
