Private messaging on Android. No OTP. No address book required.
Why Buzzio
A Buzzio ID, a seed phrase, and sealed chats — without SMS OTP or a SIM-bound identity.
View all reasonsHow Buzzio works
Sealed chats keep zero durable conversation metadata on our servers. Shared Feature mode stores plaintext so feeds, roles, and backscroll work — and we say so up front.
Privacy — sealed
Zero durable metadata
E2EE · zero durable chat metadata after delivery · history on your devices
Timed QR E2EE sessions · zero durable chat metadata after expiry
Encrypted groups · no full open archive for late joiners
Features — shared
Stores what the product needs
Shared backscroll in plaintext on our servers — not E2E
Channels, roles, and events — plaintext rooms, not E2E
One-to-many feeds in plaintext — not sealed E2EE by design
Choose Privacy (E2E sealed groups) or Features (open-history shared backscroll) — password protection, screenshot blocking, and timers when you want them.
How groups work
Voice and video on your phone — and share your screen on a 1:1 call. Same encryption as your messages. We don't keep a recording.
