Description
Zerion is a private messenger. It runs over Tor, so your IP address is hidden from the people you message and from the network. There's no phone number, no email, no account on a server. Your messages live encrypted on your device.
Everything is end-to-end encrypted with hybrid post-quantum cryptography — both today's standard algorithms and the new NIST quantum-resistant ones. If quantum computers arrive sooner than expected, your old conversations stay safe.
WHAT YOU CAN DO
• One-to-one chats with end-to-end encryption • Group chats up to a few dozen people • Voice calls over Tor • Send photos, videos, voice notes, and documents • Disappearing messages • A built-in vault for passwords, notes, and private files • Channels — a publisher-to-subscriber broadcast layer with optional discussion threads (new in 2.0)
NEW IN 2.0 — CHANNELS
Channels are a one-to-many space. One person writes, many people read.
• Public channels: anyone with the invite link can subscribe • Private channels: subscribers ask to join, the owner approves • Discussion threads: owners decide whether subscribers can reply under each post • Editor delegations: let trusted people post without sharing your identity key • Pinned posts, reactions, attachments • No subscriber-to-subscriber metadata leaks — subscribers don't see each other
NEW IN 2.0 — HARDENED MODE (OPT-IN)
Three independent protections under Security settings, all off by default:
• Refuse to start on tampered devices (unlocked bootloader, modified system) • Refuse to start when a debugger, root, or hooking framework is detected • Sign out automatically (or wipe) if ADB or file transfer is enabled over USB
PRIVACY AND SECURITY
• Tor-only transport — no Wi-Fi, Bluetooth, or LAN exposure • No phone number, no email, no central server • No telemetry, no analytics, no crash reporting • No logging of any kind — verified at build time • Encrypted at rest with SQLCipher and a password-derived key • Screenshots blocked inside the app • Notifications never show message previews • Open source on GitHub, GPL v3, audited per release
WHO IT'S FOR
People who want to talk to other people without a third party in the middle. Journalists and their sources, activists, lawyers and their clients, people in countries that block secure messengers. Anyone who doesn't want to hand a phone number to a tech company every time they install a messenger.
