◆ About

About Capsule

Privacy-first encrypted messaging with zero data retention.
Our Mission
To build a messaging platform where privacy is not a promise — it’s the default. Zero collection, zero identification, zero trace.
◆ Principles
👻
Zero Knowledge
The server never sees your messages. End-to-end encryption means the keys stay only on your device.
🌑
Zero Identity
No registration required for basic use. No email, no phone number, no name. Download and start.
⚡
Zero Retention
Everything auto-deletes. Built-in TTL on every message. No archive, no backup, no trace.
◆ 4-Layer Encryption Architecture
01
Transport Layer
TLS 1.3 secured with certificate pinning
02
Message Layer
AES-256-GCM per message with unique key
03
Identity Layer
RSA-4096 for key exchange and verification
04
Discovery Layer
HMAC-SHA256 with server-side secret — even if breached, phone numbers cannot be reversed
