## What is Secure Chats?

SecChats is a private, end-to-end encrypted messenger for one-to-one
and group conversations. Every text and photo you send is encrypted on
your device with AES-256-GCM under a key derived from an ECDH
handshake with the recipient. The server only sees ciphertext.

No phone number. No email. No ads. No tracking.

Why SecChats

— True end-to-end encryption. Messages are encrypted on your device
  before they leave it and only decrypted on the recipient's. The
  SecChats server cannot read them. Neither can we.
— No phone number or email. Sign up with a display name. The server
  assigns you an opaque user ID; share that with friends to start
  chatting.
— Private by design. The on-device database is wrapped in an
  additional AES-256-GCM layer, so a stolen or seized device does not
  hand over your conversation history.
— Add friends face-to-face by scanning a QR code — keys never touch a server.
— Photos, text, groups. Send messages and images to friends or
  groups; create groups and share QR-code invitations; scan a QR code
  to join a group you were invited to.
— Seven languages. Switch the interface between System default,
  English, Romanian, Japanese, French, German, Spanish, and Brazilian
  Portuguese from Settings.
— Open API and reference client. The protocol is documented and
  shipped alongside an open-source Java reference client, so you can
  audit or rebuild the messaging stack yourself. SecChats does not
  lock you in.

What's in the app

— Friends tab — your contacts, groups, pending requests, and
  group invitations. New activity is flagged with a small dot.
— Chat tab — bubble-style conversations with copy/delete on each
  message, clickable URLs, and full-screen image previews.
— Settings tab — language picker, message and account wipe,
  Banned Channels ledger for anyone you have reported and removed.

Security details

— Wire format: AES-256-GCM under an ECDH-derived shared secret.
— At-rest format: AES-256-GCM with a per-install key, layered over
  every text payload and every image payload before SQLite ever
  sees the bytes.
— Profanity filter on display names and group names, backed by a
  curated word list.
— Open verification: the protocol and reference client are public.

Multi-line reply composer.
Editing a reply preserves the quoted header automatically.

Emoji reactions - long click to select one.

Notifications
You now get a notification banner when a friend sends you a message while you're on the Friends or Settings tab, even if their chat was the last one you opened.

Chat input
The message field now expands to multiple lines as you type (up to 5 visible lines, then scrolls internally).
Return inserts a newline; the up-arrow Send button is the only submit action.
Tapping Send with an empty field dismisses the keyboard.
Tapping anywhere on the message list also dismisses the keyboard.

Polish
The three-dots message menu is easier to tap.
Fixed the bottom bubble sliding behind the input row after an edit.

Save images straight to your Photos library from the chat menu.
Join / leave a group and the chat now records it automatically.
