DChat: Secure Chat & Calls

DChat is a secure messenger built for people who take privacy seriously.
Every message is end-to-end encrypted with post-quantum cryptography, so
your conversations stay private — today and against the computers of
tomorrow.

WHY DCHAT

Most encrypted messaging apps rely on cryptography that a future quantum
computer could break. Messages captured today can be stored and decrypted
later. DChat uses ML-KEM, a post-quantum key exchange standard, so your
conversations are protected against that threat.

END-TO-END ENCRYPTED MESSAGING
• Private 1-to-1 chats, encrypted on your device
• Group chats with the same protection
• Photos, videos, documents and voice notes — all encrypted
• Only you and the people you're talking to can read your messages

VOICE AND VIDEO CALLS
• Crystal-clear voice calls
• Face-to-face video calls
• Group calls with multiple participants
• Peer-to-peer connections — your media doesn't sit on our servers
• Share a meeting link so anyone can join, no account needed

PRIVACY YOU CONTROL
• Message requests — strangers can't reach you uninvited
• Block contacts, and unblock them any time
• Choose who sees your profile photo
• Silence unknown callers
• Your contacts are matched on your device and never uploaded

BUILT ON DECENTRALIZED IDENTITY
DChat uses your NCOG wallet as your identity, so there's no central
account database to breach. You own your identity, and you can take it
with you across the DSuite apps.

FEATURES AT A GLANCE
• Post-quantum end-to-end encryption
• Secure group chat
• Encrypted voice and video calling
• Shareable meeting links for guests
• Encrypted file and media sharing
• Message requests and contact blocking

REQUIREMENTS
DChat requires the NCOG wallet app to sign in. Your wallet is your
identity — there's no password to leak and no phone number database to
breach.

PRIVACY COMMITMENT
We don't sell your data. We don't profile you for advertising. Your
messages are encrypted before they leave your device, and we cannot read
them.
