Zerion Chat 앱 분석 (9월 20일)

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. That means both today's standard algorithms and the new NIST quantum-resistant ones, refreshed on every message instead of just the first handshake. 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 and video calls over Tor • Send photos, videos, voice notes, and documents • Disappearing messages, with an optional default timer for new chats • A built-in vault for passwords, notes, and private files, now with search and sort • Channels, a publisher-to-subscriber broadcast layer with optional discussion threads CALLS OVER TOR Calls run peer-to-peer through Tor. No VoIP server, no STUN/TURN, no IP exposure. The audio and video go straight between devices, encrypted. • Voice calls are on by default. You can turn them off any time in Settings • Video calling is available as an opt-in beta • Calls show a clear "Reconnecting" status and recover on their own if the connection briefly drops 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 • Mute notifications per channel • Subscribers never see each other, so there is no subscriber-to-subscriber metadata 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 • Clipboard auto-clears after you copy sensitive items • Open source on GitHub, GPL v3, audited every 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.
