Chat

Personal text encryption,
with clear limits.

Buzzz is the operating system for local commerce and digital storefronts — and chat is built right into it. Current personal text-message bodies are encrypted separately for participant devices using Matrix Olm. Calls use WebRTC transport encryption. Metadata, service content, decrypted device caches or backups, commerce records and media are outside the text-message encryption guarantee.

Matrix Olm-encrypted personal text, 1:1 and in groups.

Supported personal text is encrypted on the sender's device separately for every participant device using Matrix Olm. Buzzz stores ciphertext for those message bodies.

  • Sends fail closed if every intended recipient device cannot be encrypted.
  • Group text uses per-device encrypted fan-out.
  • Metadata, service content and decrypted caches or backups are outside this guarantee.
  • Historical Signal-encrypted bodies require a previously decrypted local cache copy.

Hey! Is the linen suit still in my size?
Yes — got one left. Want me to hold it? 🙌
Please do. I'll swing by after 5.
Done. It's tagged with your name.
🔒 Matrix Olm-encrypted text

Voice & video calls use encrypted transport.

Talk it through when typing isn't enough. Voice and video calls use WebRTC DTLS-SRTP to encrypt media in transit between participants or a relay. Buzzz does not yet claim a separate, independently authenticated app-level E2EE layer for calls.

  • Clear 1:1 calls that connect fast.
  • Group calls for the team, the family or the crew.
  • Encrypted WebRTC media transport for every call.

Optional message-expiry controls.

Temporary-message settings ask supported clients to remove eligible messages after the selected interval. Recipients can still copy, capture, forward or retain content, and deletion is not guaranteed on every device or backup.

  • Flip it on per chat, whenever you want.
  • Treat it as a cleanup preference, not an anti-copy control.
  • Avoid sending secrets that a recipient must never retain.

🔒 Matrix Olm-encrypted text

End-to-end encrypted media is in progress.

Personal-chat media sends are temporarily paused while client-side file encryption and per-device media-key wrapping are completed. Supported personal text can still be sent with Matrix Olm encryption; structured or service content has different protections.

  • No silent fallback to an unencrypted file URL.
  • Media will return after end-to-end file-key delivery is complete.
  • Do not send sensitive documents through media until then.

Optional client-encrypted backups.

Message-history backups are encrypted on the client with an account-bound recovery key before upload. Buzzz cloud storage receives ciphertext rather than the cached plaintext history.

  • Restore requires the recovery key to be available on the device.
  • AES-256-GCM detects a wrong key or modified backup.
  • Restore after the recovery key is available on the device.
