Zerion Verschlüsselte Nachrichten App für Android Beschreibung
Zerion is a private messenger. It runs over Tor, so your IP address is hidden from the people you message and from the network. Theres 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 todays 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
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 dont see each other
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 ITS 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 doesnt want to hand a phone number to a tech company every time they install a messenger.
WHAT IT WONT DO
- It wont message people who arent on Zerion
- It wont work without an internet connection (Tor needs one)
- It wont restore your account if you forget the password — there is no recovery, and thats the point
