About this app
ChatOk is the ultimate fortress for your communications. We have built a messaging tool where privacy isn't just a featureāit is the absolute standard. No registrations, no trackers, and zero personal footprints left behind.
š« Radical Privacy: Zero Personal Data
No Phone Number or Email: You do not need to link a SIM card or any personal account to start chatting.
100% Anonymous Registration: Your identity is protected by a nickname and a cryptographic key generated locally on your device.
No Tracking: Forget about ads and analytics; we do not collect metadata or sell your information.
Serverless Feel: Firebase only acts as a relay for encrypted "noise," which is deleted immediately after delivery.
š Fully Encrypted Media & Files
E2E File Sharing: Send documents and files (up to 25 MB) with end-to-end AES-256-GCM encryption.
One-Shot Photos (View Once): Send ephemeral images that self-destruct automatically after being viewed by the recipient.
2-Phase Secure Deletion: Temporary photos are physically wiped from memory to ensure no forensic traces remain.
Encrypted Local Storage: Your message history on the phone is shielded by an SQLCipher database.
š”ļø Military-Grade Security
Post-Quantum Encryption (PQXDH): Protect your messages with ML-KEM-1024 and X25519 algorithms, designed to withstand future quantum threats.
Built-in Tor Routing: Stay invisible by hiding your real IP address through native Tor integration.
Double Ratchet & PFS: Every message uses unique keys; if one is compromised, your past and future history remains safe.
Dummy Traffic: Mask your real activity patterns with configurable cover traffic to prevent traffic analysis.
