Secure Communication Built for Privacy
GSTNet combines end-to-end encrypted communications with a peer-to-peer-first architecture. Direct device-to-device connectivity is preferred whenever network conditions allow, while secure backend infrastructure supports account management, security, and connectivity when required.

Why Peer-to-Peer Changes the Architecture
Every other messaging app routes your data through central servers with full access to content. GSTNet is designed so we don't have the keys to decrypt your protected communications, even though backend infrastructure supports the account and connectivity layer.
Peer-to-Peer First Architecture
GSTNet is designed to establish direct encrypted connections between devices using WebRTC whenever possible. When direct connectivity is unavailable, a secure relay maintains the connection.
AES-256-GCM Encryption
Communication content is encrypted before it leaves your device. Global Space Technology does not possess the cryptographic keys required to decrypt protected content.
Global by Design
The website interface is available in 34 languages. Built to serve users worldwide, including in regions where other messaging apps face restrictions.
Real-Time Message Translation
The app can translate incoming messages using Apple's on-device Translation framework, supporting 100+ languages. Opt-in per message or automatic — the original text is always available with a tap.
Multi-Protocol Connectivity
Wi-Fi and cellular connectivity today, with satellite and RF transport layers on our future roadmap — see our roadmap section for what's live now versus planned.
Your Identity, Your Control
Your GST-ID is a unique account identifier — not your password, and not proof of account ownership on its own. No phone number or real name is required to register.
Forward Secrecy
Each session generates new encryption keys, so a compromise of one session's key does not expose other sessions.
How It Works
Get secure in four simple steps. No technical knowledge required.
