About this app
Ghost Protocol is a privacy-first encrypted messenger built for anyone who needs real security — not just the appearance of it.
SECURITY
• End-to-end encrypted with Signal's Double Ratchet + ML-KEM-1024 (post-quantum)
• No phone number or email required — your identity is a cryptographic key pair
• Perfect forward secrecy — past messages stay safe even if keys are compromised
• Post-compromise security — future messages recover automatically after a breach
FEATURES
• Private chats with read receipts and disappearing messages
• Group chats — every message individually encrypted per member, no group key server
• Voice calls — encrypted with XChaCha20-Poly1305, real-time pitch shifting (Ghost Voice)
• Voice notes — metadata stripped before send
• Anonymous Inbox — receive tips from strangers with no account required
• File sharing — all metadata stripped before transmission (GPS, timestamps, camera info)
• Tor transport — route all traffic through Tor with one tap
PRIVACY
• Zero data collected — no IP addresses, no location, no analytics
• No ads, no trackers, no cloud backup
• Open source and reproducible builds — verify what you're running
Ghost Protocol is free and always will be.
