Zerion Chat
Private Messaging, Reimagined
• Zerion is built for those who refuse to compromise on privacy.
• By routing all traffic through Tor, we eliminate the need for phone numbers, email addresses, or centralized servers.
• Your conversations stay strictly on your device, shielded by cutting-edge hybrid post-quantum encryption that secures your history against both current threats and the looming power of future quantum computing.
Core Capabilities
• Total Anonymity: No accounts, no metadata, and no third-party oversight.
• Versatile Communication: Engage in encrypted one-to-one chats, group discussions, or seamless voice and video calls—all directly peer-to-peer over Tor.
• Content Control: Share media and documents with confidence using self-destructing messages.
• Private Vault: A secure, searchable local repository for your most sensitive notes and credentials.
Unified Broadcasts via Channels
Distribute information on your terms without exposing your audience.
• Flexible Access: Manage public links or manually approve private subscribers.
• Metadata Protection: Subscribers remain invisible to one another, preventing third-party tracking.
• Enhanced Interaction: Utilize discussion threads, reactions, and delegated posting rights while maintaining total control over your space.
Hardened Security Features
For users requiring extreme protection, our opt-in Hardened Mode offers three layers of defense:
• Integrity Checks: The app refuses to initialize on tampered, rooted, or modified devices.
• Debugger Detection: Blocks execution if hooking frameworks or debuggers are present.
• Remote Threat Mitigation: Automatically signs out or wipes data if USB file transfers or ADB activities are detected.
Absolute Privacy Standards
• Zero-Knowledge Architecture: No telemetry, analytics, or crash reports. We log nothing.
• Local Security: Data is protected at rest using SQLCipher, with built-in safeguards like screenshot blocking, auto-clearing clipboards, and notification privacy.
• Transparent Foundation: Fully open source (GPL v3), regularly audited, and built for those who need to communicate safely—from journalists and activists to anyone reclaiming their digital autonomy.

FAQ
Q: Is my conversation history stored on a server?
A: No, your conversations are never stored on a server. Every message you send or receive stays strictly on your local device. Because we do not use centralized servers, we have no access to your history, and there is no cloud database where your private interactions could be intercepted or leaked.
Q: How does Zerion protect me against future quantum computing threats?
A: We stay ahead of the curve by implementing cutting-edge hybrid post-quantum encryption. This protects your current communication not just from existing threats, but also from the future potential of quantum computers that might otherwise be able to decrypt legacy encryption standards.
Q: Do I need to create an account or provide any personal details to use Zerion?
A: Absolutely not. Zerion is designed for total anonymity. We do not require phone numbers, email addresses, or any personal identification to get started. You can begin communicating immediately without ever handing over your identity.
