How we protect your data

Every layer of our stack is designed with security and privacy as the default.

End-to-End Encryption

Messages are encrypted on your device before being sent. We never have access to your encryption keys or plaintext data.

Zero-Access Architecture

Even our own engineers cannot read your emails. Your data is encrypted in a way that only you can decrypt it.

Secure Infrastructure

All data is stored in SOC 2 Type II certified data centers with full disk encryption and network isolation.

Open Source Cryptography

Our encryption libraries are open source and regularly audited by independent security researchers.

Two-Factor Authentication

Protect your account with TOTP, hardware security keys (FIDO2), or biometric authentication.

GDPR & CCPA Compliant

We comply with international privacy regulations and give you full control over your personal data.

How encryption works

A simplified overview of how your messages stay private.

01

You compose a message

Your email client generates a unique encryption key for each message using AES-256.

02

Encrypted before sending

The message is encrypted locally on your device before it ever touches our servers.

03

Secure transmission

Encrypted data travels over TLS 1.3. Even if intercepted, it's unreadable without the key.

04

Only the recipient can read it

The recipient's private key decrypts the message on their device. No one else — including us — can read it.
