PRIVATE MESSAGING

Say it.
Then it's gone.

QUAQ is a messaging app where conversations are ephemeral, files vanish after download, and encrypted dead drops let you share secrets with anyone — without leaving a trace.

FEATURES

Everything you need. Nothing you don't.

Ephemeral chats

Messages live in memory. Kill a chat and everything disappears — for both sides. No backups, no server copies.

Group chats

Create group conversations with multiple people. Same ephemeral rules apply — anyone can kill the chat.

Secure file sharing

Send images, documents, and files. Once the recipient saves the file, it's automatically wiped from the cloud.

On-device encryption

Dead drop messages are encrypted with AES-256 on your phone before upload. The server never sees plaintext.

Real-time delivery

WebSocket-powered live updates. Messages and chat list changes appear instantly — no pull-to-refresh needed.

No ads. No tracking.

Zero analytics, zero advertising, zero data harvesting. QUAQ exists to let you communicate — that's it.

DEAD DROPS

Encrypted messages for anyone.

Dead drops are anonymous encrypted posts visible to all QUAQ users — but only readable by someone who has the 64-character decryption key.

  • AES-256-CTR encryption happens entirely on your device
  • The server stores only ciphertext — it can never read your message
  • Share the key however you want: in person, on paper, through another app
  • Your own posts auto-unlock on your device
