BlackX Private Chat

End-to-end encrypted chat and calls — username accounts, invite-only, no phone number.

Black-X is a private messenger built around end-to-end encryption. Create an account with a username and an invite — no phone number required.

WHAT YOU GET • Encrypted text, media, and voice notes • One-to-one audio and video calls • Multiple accounts on one device (up to 5) • Official Black-X News channel (read-only updates) • Multi-device support • Local vault backup on your device • Account deletion from Settings

INVITE-ONLY New accounts need an invite code from someone you trust. This keeps the network intentional.

PRIVACY-FIRST Message content is designed so only conversation participants can read it — not the relay operators. Push notifications stay generic (no message body, no plaintext sender on the push channel).
