Encrypted Team Messaging. No Servers. No PII.

Messaging. Files. VPN.

End-to-end encrypted collaboration with no data on servers. No phone number or email required.

No Central Server

Messages travel directly between your team's devices. No central server means no single point of failure, no data at rest, and no third-party access to your communications.

No PII Required

No phone number. No email address. No personal information of any kind. Your identity is self-custody, generated and stored only on your device.

End-to-End Encrypted

Every message, file, and video is encrypted before it leaves your device. Not even Diode can read your communications. ISO 27001 and SOC-2 compliant.

How Diode compares to other platforms.

Most messaging platforms store your data on their servers, require personal information to register, and can access your messages. Diode is architecturally different.

Typical Platforms

Messages stored on company servers where they can be accessed, subpoenaed, or breached
Phone number, email, or government ID required to register
Metadata about contacts, timing, and frequency stored centrally
Encryption is optional, partial, or server-side only

Diode Collab

Peer-to-peer: messages travel directly between devices with no server in the middle
No phone number, email, or personal information required
No metadata stored. Not even Diode knows who you talk to
All messages end-to-end encrypted by default, always, including group chats

Everything your team needs in one app.
