Core 51 Business Messenger

Core51, Inc.

About this app

Core51 is a corporate messenger for day to day work: decisions, approvals, handoffs, and sensitive discussions. End to end encryption protects confidentiality by default: messages are encrypted on device and the server is treated as untrusted. Only participants can read the content. And if something goes off plan, conversations can be exported with verifiable proof suitable for arbitration, audits, and disputes.

Features:
End-to-end encryption for all chats
Message as proof of a deal
Two export levels: pre-trial dispute resolution and court-grade forensics
No chat deletion (you can freeze a chat and move it to the Frozen Chats)
Custom chat names
Color labels for chats
