Detailed Description
Conversations (Jabber / XMPP) – Secure and Decentralized Instant Messaging
Conversations is an open-source instant messaging application designed for the Jabber (XMPP) protocol. It prioritizes user privacy, security, and decentralized communication, allowing individuals to connect without relying on a single central server. The app supports end-to-end encryption, file sharing, and voice calls, making it a robust alternative to mainstream messaging platforms. It is particularly valued by users who seek control over their data and independence from corporate ecosystems.
Chapter 1: Function
Conversations provides a comprehensive set of core features centered on the XMPP protocol. Users can send text messages, share images, videos, and files, and make audio calls directly through the app. It supports multiple accounts and simultaneous connections to different XMPP servers. Key functional strengths include end-to-end encryption via OMEMO and OpenPGP, ensuring message confidentiality. The app also offers message synchronization across devices, read receipts, typing indicators, and offline message storage. Its interface is clean and responsive, with notification customization and group chat management capabilities. These functions collectively deliver a reliable and secure messaging experience without compromising usability.
Chapter 2: Value
The primary value of Conversations lies in its commitment to privacy and decentralization. Unlike proprietary apps that centralize user data on corporate servers, Conversations leverages the XMPP protocol to allow users to choose their own server, giving them full ownership of their communications. This eliminates the risk of data mining, surveillance, or service shutdowns by a single entity. The app uses industry-standard end-to-end encryption by default, preventing third-party access to message content. Its open-source nature ensures transparency, enabling security audits and community-driven improvements. Additionally, Conversations supports federation, meaning users on different XMPP servers can communicate seamlessly, breaking down walled gardens. This combination of privacy, control, and interoperability makes it an invaluable tool for journalists, activists, and anyone concerned about digital sovereignty. Its low resource consumption and offline message handling also enhance reliability in low-connectivity environments.
Chapter 3: Scenarios
Conversations primarily serves privacy-conscious individuals, security professionals, and organizations that require confidential communication. Key target users include journalists who need to protect sources, activists operating under surveillance, and companies seeking secure internal messaging without relying on third-party platforms. It is also popular among tech enthusiasts who prefer open-source solutions and users in regions with restrictive internet policies, as decentralized servers can bypass censorship. Everyday use cases include secure team collaboration, personal chats with family or friends who value privacy, and integration with other XMPP-based services for automated notifications or project management. The app is also suitable for educational institutions or non-profits that want to maintain data ownership and avoid commercial tracking.

Frequently Asked Questions
What does Conversations app do?
Conversations is an open-source instant messaging app for XMPP (Jabber) protocol. It provides end-to-end encryption via OMEMO, supports file sharing, voice messages, group chats, and works with any public or private XMPP server. It focuses on privacy and decentralized communication, requiring no phone number or centralized account.
Is Conversations free to use?
Conversations is available on Google Play for a small one-time purchase (approximately €4-5). However, its source code is fully open-source, so users can compile or install it via F-Droid for free. There are no in-app purchases or subscriptions. You need only an XMPP account from a server (many free servers exist) and internet access.
Can I use Conversations on iOS or desktop?
Conversations is designed exclusively for Android (version 5.0+). No official iOS or desktop version exists. For cross-device use, you can pair with other XMPP clients on iOS (e.g., Monal) or desktop (e.g., Gajim, Pidgin) using the same account. Conversations supports OMEMO encrypted synchronization between devices via your XMPP server.
How does end-to-end encryption work in Conversations?
Conversations implements OMEMO encryption (based on the Signal Protocol) by default for direct and group messages. It is turned on automatically for contacts who also support OMEMO. You can verify fingerprints for extra security. Encryption applies to text, files, and voice messages. Unencrypted fallback is possible but discouraged. No third party can read encrypted content.
Does Conversations support video calls or voice calls?
Conversations does not include built-in voice or video calling. It is purely a text and file sharing messenger. For real-time calls, you can pair it with external XMPP-compatible apps like Jitsi Meet or Linphone that share the same XMPP account (via server-side features like Jingle). The app focuses on asynchronous messaging and privacy.
