SYNRO
End-to-end encrypted messenger with anonymous voice calls, voice anonymization, and self-destructing messages.
// How Synro works
Privacy Without Compromise
Every feature is built around one principle: your data belongs to you alone.
Anonymous Voice Calls
Call anyone in your channel. Your voice is anonymized in real-time before it leaves your device — the listener never hears your real voice.
Burn-After-Read Drops
Send a secret message or file. The recipient reads it once — then it's gone forever. No traces, no copies, no recovery.
Voice Anonymization
Every voice message is processed through formant transformation. The original voice pattern is mathematically destroyed. Irreversible.
Auto Metadata Stripping
Photos, files, documents — all EXIF, GPS, camera data is automatically removed before encryption. Zero digital footprint.
And everything is: End-to-end encrypted. Self-destructing. Controlled by you, not by us. Synro stores encrypted data with auto-expiry — we deliver what we can't read.
// Under the hood
Zero-Knowledge Protocol
Whether you message by username or join via link — the server only sees encrypted data it cannot read.
Connect
Find a user by @username or share an invite link — both create an encrypted channel
Derive Keys
Client generates unique encryption keys. Server never knows them.
Encrypted Relay
Messages are E2E encrypted on your device. Server stores ciphertext with auto-expiry — it cannot read the content.
Auto-Destroy
Channels self-destruct by time or on demand. No traces remain.
// Key derivation from shared secret
S = random(32 bytes)
chat_id = SHA256(S)
auth_key = HKDF(S, "auth")
ratchet_seed = HKDF(S, "ratchet")
// KDF Ratchet — Forward Secrecy per message
// Voice Anonymization
Your Voice, Unrecognizable
Every voice call and voice message is processed through formant transformation. The original voice pattern is mathematically destroyed before transmission.
// Core features
Built for Privacy
Every feature is designed to protect your identity, your voice, and your data.
Anonymous Voice Calls
Real-time voice calls with built-in anonymization. Your voice is transformed before transmission — the recipient never hears the original.
Voice Anonymization
All voice messages are processed through formant destruction. The original voice pattern is mathematically irrecoverable.
Metadata Stripping
All files and photos are automatically cleaned of EXIF, GPS, camera data before encryption. Zero digital footprint.
Synro Drop
Send a one-time encrypted message. It self-destructs after being read. Perfect for passwords, secrets, and sensitive data.
Self-Destructing Channels
Set a time limit or destroy manually. When the timer expires, the entire conversation disappears permanently.
End-to-End Encryption
AES-256-GCM with HKDF key ratcheting and forward secrecy. Every message encrypted on-device with unique keys. Server sees only ciphertext.
// Synro Drop
Read Once. Gone Forever.
Send a burn-after-read message. Once opened, it self-destructs — no traces, no copies, no recovery.
The package is at the north dock. Gate 7. Code: 4821.
Synro Wallet
Non-custodial crypto wallet built into Synro. Send, receive, and swap tokens across EVM chains. BIP-39 seed phrase. Zero KYC.
Not Another Messenger
Synro is built for people who take privacy seriously. Compare the fundamentals.
