Why Kelpie

SECURITY WITHOUT SACRIFICE

🔐

Zero-Access Architecture

Your encryption keys never leave your device. Even we can't read your messages — and that's by design.

🌊

Deep Anonymity

No tracking. No profiling. No metadata harvesting. Your communications remain truly private.

⚡

Lightning Protocol

Built on modern infrastructure for speed without compromising security. Encrypted in milliseconds.

🛡️

Fortress Storage

256-bit AES encryption at rest. Your data is protected even against physical access attempts.

🔑

Hardware Key Support

Native support for YubiKey and FIDO2 devices. Phishing-resistant authentication as standard.

🌐

Open Standards

Built on proven cryptographic standards. No proprietary black boxes. Fully auditable security.
