Briar

Overview

• Briar is a secure messaging application aimed at activists, journalists, human‑rights defenders, and anyone who requires a reliable, censorship‑resistant way to stay in touch.

• Unlike conventional messengers that depend on a centralized server, Briar’s architecture is completely peer‑to‑peer: each message is exchanged directly between the devices of the participants.

Communication Channels

1. Offline sync

• When the Internet is unavailable, Briar can still deliver messages using Bluetooth, local Wi‑Fi, or by physically moving a memory card from one device to another.

• This is ideal for field work or crisis situations where connectivity is disrupted.

2. Online sync

• When the Internet is accessible, Briar routes traffic through the Tor network, hiding the origin, destination, and timing of the communication from surveillance systems and network observers.

Core Features

• Private one‑to‑one messaging with end‑to‑end encryption.

• Group chats that can include any number of participants, each conversation protected independently.

• Forums and distributed blogs that allow asynchronous discussion without a central host.

• All data resides only on the user’s device unless deliberately shared with other participants.

Privacy & Security

• No advertisements, analytics, or tracking code; the app does not collect usage data.

• The complete source code is publicly available and has undergone professional security audits.

• Every release is reproducible: anyone can compile the published source and verify that the binary they download matches the audited code exactly.

Development & Governance

• Maintained by a small, non‑profit team dedicated to open‑source principles and digital rights.

• Funding comes from donations and grants, ensuring that commercial pressure does not compromise the project’s mission.

Secure Messaging

• Briar therefore offers a robust, self‑contained communication platform that stays functional under censorship, network outages, or intense surveillance, while keeping user data under the sole control of its owners.

FAQ

Q: Can I still send and receive messages when I have no Internet connection?

A: Absolutely. Briar’s offline sync lets you exchange messages using Bluetooth, local Wi‑Fi, or by moving a memory card from one device to another. This feature shines in field work, disaster zones, or any situation where the Internet is unreliable or deliberately blocked.

Q: What happens to my messages when I am online?

A: When an Internet connection is available, Briar automatically routes all traffic through the Tor network. Tor hides the origin, destination, and timing of each message, making it extremely difficult for network observers or surveillance systems to trace your communications.

Q: Is my one‑to‑one chat truly private?

A: Yes. Every one‑to‑one conversation in Briar is protected by end‑to‑end encryption. Only the two devices participating in the chat hold the keys needed to decrypt the messages, so nobody—including the Briar developers—can read the content.
