What is
Mujō?
A messaging app built around a single idea: that some words should not outlast the moment they were written in.

How to connect
Two ways. Both leave no trace of who you are.
- Your contact shares their nickname with you — by message, in person, however you like.
- Install Mujō. Create your nickname if you want one, or skip it.
- Search for their nickname. A temporary pairing code appears.
- Copy it and send it back to them through any channel.
- They paste it into Mujō and confirm. Connected.
- Install Mujō. No nickname needed.
- Your QR code is on screen. Below it, a short pairing code.
- Copy the code and send it — text, email, anywhere.
- They paste it into Mujō. Connected. No names exchanged.
-
No account. No phone number.
Mujō does not ask who you are. Your identity is generated on your device and lives only there. Nothing to register, nothing to verify, nothing to lose.
-
End-to-end encrypted
Every message is encrypted on your device before it travels anywhere. The server relays an opaque blob it cannot read. Not even we can see what you write.
-
Messages that vanish
Ephemeral by design. Once read - or when you choose - they are gone. No archive, no backup, no cloud copy waiting somewhere you forgot about.
-
Connect via QR
Pairing is direct and physical - scan a QR code in person or share it through a trusted channel. No usernames to search, no directories to expose you.
Mensagens de voz, imagens, video, documentos
Envie mensagens de voz encriptadas, fotos, videos e documentos diretamente na conversa. Os media sao encriptados antes de sair do seu dispositivo e armazenados em fragmentos no relay. Nada e guardado de forma legivel, em lugar nenhum.
-
No ads. Ever.
Mujō is funded by subscriptions. There is no advertising SDK, no analytics, no behavioural data collected or sold. The business model is your trust, not your attention.
Implementações privadas
O Mujō está disponível como aplicação pública, mas a mesma infraestrutura de comunicação também pode ser implementada para ambientes organizacionais dedicados.
Instâncias hospedadas dedicadas, aplicações white-label e implementações on-premise estão disponíveis mediante solicitação para equipas que precisam de comunicação privada e efémera sem exposição centralizada de credenciais.
As implementações privadas podem incluir integração baseada em API com fluxos de trabalho internos, limites operacionais dedicados e distribuição específica da organização.
Para licenciamento ou pedidos de implementação privada, contacte licensing@parta.app.
Available on
Mujō is currently available for Android and Windows. iOS will follow when the time is right.
