## What is Nitro Messenger?

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.


## Version history (last 3 releases)

### 1.2.1 — 2026-07-13

What's new in 1.2.1:

Calls, upgraded:
• Callers now see "Ringing…" the moment your contact's phone rings
• Busy and declined calls are finally honest — no more guessing why a call ended
• Minimize a call and keep using the app; a floating bar brings you back
• The screen turns off against your ear during voice calls
• Mute from the lock screen or CarPlay now actually mutes
• Clearer call history: repeat calls group together, timers show hours

Chat, steadier:
• No more jumps — reading old messages is never yanked to the bottom
• A jump-to-latest button with a new-message counter
• Photos keep their exact size while loading — no more shifting bubbles
• Read receipts update live while the chat is open
• Reply by swiping a message; date headers keep long chats organized

Notifications, finally like they should be:
• See the sender and the message itself (decrypted only on your device — you can turn previews off)
• Reply and mark-as-read straight from the notification
• Tapping a notification opens the right conversation
• Grouped neatly per chat, no more duplicate banners

Sharper media:
• Crisper photo and video previews in chat
• Voice notes show a real waveform — drag to seek, play at 1.5x or 2x
• Media you've opened once now opens instantly, even offline

Every message, call, and file stays end-to-end encrypted with post-quantum cryptography.

### 1.0.1 — 2026-06-30

This update brings reliability and sharing improvements:

• Share photos, videos, and files in chat — all end-to-end encrypted

Nitro keeps every message, call, and file end-to-end encrypted with post-quantum cryptography.
