Nitro is a private messenger built on a simple promise: the server cannot read your messages. Content is end-to-end encrypted with a post-quantum hybrid ratchet, so your conversations stay yours — even against tomorrow's computers. WHY NITRO • End-to-end encrypted messages, calls and media — keys live only on your device. • Post-quantum hybrid encryption, not just classic crypto. • The server is a "dumb carrier": it routes opaque, encrypted envelopes and never sees content. • No ads. No trackers. No third-party analytics. Your address book is never uploaded. • Your identity is a @username — your phone number is never shown to anyone. FEATURES • 1:1 chat with delivery receipts. • Photo sharing — images are encrypted on-device before they ever leave. • Voice & video calls with the native call experience (CallKit). • Group chats. • On-device, encrypted history — losing the server never loses your messages. • App lock with Face ID. PRIVACY YOU CAN VERIFY Every chat shows an encryption indicator, and you can confirm a contact face-to-face with a safety number. Delete your account anytime from Settings — your identity and history are wiped from the device. Nitro is single-device by design: no desktop or multi-device surface to attack.
