Privacy Policy

Last updated: March 16, 2026

Overview

Unsync is a privacy-first, peer-to-peer encrypted messenger. We do not collect, store, or sell your personal data.

Data We Do NOT Collect

• Your messages - they are end-to-end encrypted and never stored on any server
• Your contacts or contact list
• Your phone number - Unsync does not require one
• Your location
• Any personally identifiable information

How Unsync Works

Messages travel directly between devices using peer-to-peer connections encrypted with the Signal Protocol. Our coordination server only facilitates the initial connection handshake - it never reads, stores, or logs your messages.

FCM (Firebase Cloud Messaging)

Unsync uses Google Firebase Cloud Messaging solely to wake your device when you receive an incoming call while the app is not running. No message content is transmitted through FCM.

Data Storage

Messages are stored locally on your device only, protected by your device security and optional biometric lock.

Third Parties

Unsync does not share any data with third parties. We do not use analytics, advertising SDKs, or tracking tools.
