About this app

Duo Messenger is your secure and private messaging app for family, friends, and partners, designed to keep your conversations safe with end-to-end encryption and complete anonymity. While chatting with friends, sharing files, or making voice and video calls, Duo Messenger ensures data remains private and secure.

WHY USE DUO MESSENGER:
End-to-End Encryption
All messages, including text, photos, and files, are protected with state-of-the-art end-to-end encryption. This means that only you and the intended recipient can read your messages. No third parties, including Duo Messenger itself, can access your conversations. This ensures your chats remain confidential and secure, similar to the strong encryption found in Zangi and the secret chats within Threema.

Anonymous Sign-Up
We believe in minimizing the data we collect. Duo Messenger allows for anonymous sign-up, so you can start communicating without sharing your personal phone number or email address. This enhances your anonymity and prevents unwanted tracking, a feature also explored by apps like Session.

No Data Logging
We have a strict no-logging policy. We do not store your messages on our servers after they have been delivered. This ensures that even in the event of a security breach, your past conversations remain inaccessible, a crucial aspect also emphasized by privacy-focused applications like Signal.

Secure File Sharing
Share photos, videos, and documents with confidence. All file transfers are encrypted to maintain the highest level of security. While apps like Telegram offer convenient file sharing, Duo Messenger prioritizes encryption at every step of the process.

Private Chats
Engage in one-on-one conversations with your contacts knowing that your communication is protected. This is a core function also found in apps like WhatsApp, SnapChat, Google Duo, Line, Kik, IMO, and even WeChat, but with a focus on enhanced privacy.

Enhanced Privacy Features
We are constantly working to enhance our privacy features, including features inspired by self-destructing messages found in some apps. We strive to provide comparable or superior privacy controls.

Duo Messenger offers a comprehensive suite of features designed with your privacy in mind:

Instant Messaging (IM)
Send and receive text messages instantly, with delivery confirmations. This is a fundamental feature present in almost all messenger apps.

Secure Communication
Our focus is on providing a secure communication environment. This makes Duo Messenger a suitable option for users looking for an alternative with enhanced privacy compared to standard messengers like Botim, or other general-purpose communication apps.

Private Messaging/Chats
Communicate privately with your contacts, knowing your conversations are protected.

Encrypted Messages/Encryption
All messages are encrypted to protect your privacy.

Anonymous Chat/Sign-Up
Communicate with others without revealing your personal information.

Data Protection/Privacy Focused/Message Security/Confidential Communication
We implement strict data protection measures to safeguard your information.

No Ads, No Trackers
Enjoy an ad-free experience without any intrusive trackers. This offers a different experience compared to some ad-supported platforms.

Duo Messenger provides a secure alternative for users seeking greater control over their privacy. While some applications like Zangi offer certain privacy features, Duo Messenger is built with privacy as its foundation. We strive to offer a level of security and anonymity that goes beyond basic chat apps.

We understand that privacy is a fundamental right. That's why we've designed Duo Messenger to empower you to communicate freely and confidently.

Download Duo Messenger today and experience the difference that true privacy makes.
