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.

FEATURE 01AES-256-GCM

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.

FEATURE 02Double Ratchet

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.

FEATURE 03Zero-knowledge

Voice Anonymization

Every voice message is processed through formant transformation. The original voice pattern is mathematically destroyed. Irreversible.

FEATURE 04Forward secrecy

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.

01

Connect

Find a user by @username or share an invite link — both create an encrypted channel

02

Derive Keys

Client generates unique encryption keys. Server never knows them.

03

Encrypted Relay

Messages are E2E encrypted on your device. Server stores ciphertext with auto-expiry — it cannot read the content.

04

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.
