Cipher

Blue Umbrella Software LLC

Über diese App

Cipher is end-to-end encrypted team messaging for organizations that want their conversations to stay private.

SECURE BY DESIGN
Conversations marked Secure are encrypted on your device with the Messaging Layer Security protocol (MLS, RFC 9420) before they leave it. The server relays and stores only ciphertext it cannot read. Device approval keeps a stolen password from becoming a silent new device, and every message is tied to a verified device identity.

BUILT FOR TEAMS
- Workspaces and channels for organized team conversations
- Direct messages and group chats
- File and photo sharing with encrypted attachments
- Quick meetings and huddles
- Polls, scheduled messages, and calendar integration
- Full-text search of your own messages, indexed on your device

YOUR SERVER, YOUR RULES
Cipher connects to the Cipher server your organization runs. Your data lives on infrastructure your team controls, not ours. Organization admins decide which features and integrations are enabled.

NO ADS, NO TRACKING
Cipher contains no advertising and no third-party analytics. We do not sell personal data. What you say in Secure conversations is readable only by the people in them.

Cipher requires an account on a Cipher server. Ask your organization's administrator for your sign-in details.
