Zerion is a private messenger. It runs over Tor, so your IP address stays hidden from the people you talk to and from the network itself. There's no phone number, no email, and no account on anyone's server. Your data lives encrypted on your own device — nowhere else. Everything is end-to-end encrypted with hybrid post-quantum cryptography: today's proven algorithms together with the new NIST quantum-resistant ones. Keys move forward with every message, so a key uncovered today cannot open yesterday's conversations. If large quantum computers arrive sooner than expected, what you sent in the past stays protected. WHAT YOU CAN DO • One-to-one chats, end-to-end encrypted • Group chats up to a few dozen people • Voice and video calls over Tor (opt-in, off by default) • Send photos, videos, voice notes, and documents • Disappearing messages • Stickers • Introduce two of your contacts to each other, securely • A built-in vault for passwords, notes, and private files • Channels — a one-to-many broadcast layer with optional discussion threads • Translated into more than 35 languages CHANNELS One person writes, many people read. • Public channels: anyone with the invite link can subscribe • Private channels: people ask to join and the owner approves • Discussion threads: the owner decides, per channel, whether subscribers can reply • Reactions, pinned posts, and attachments • Editor delegations: let trusted people post without sharing your identity key • Subscribers never see one another — no member list leaks between them 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 USB debugging or file transfer is switched on PRIVACY AND SECURITY • Tor-only transport — no Wi-Fi, Bluetooth, or LAN exposure • No phone number, no email,
