In-chat privacy notices
Buzzio shows a privacy notice inside each major conversation surface so “encrypted” is not treated as one global promise.
What the banners mean
| Surface | In-app notice |
|---|---|
| 1-to-1 / Whisper private | Messages and calls are end-to-end encrypted; only participants can read or listen |
| E2E groups | Sender-key end-to-end encryption; Buzzio cannot read message bodies |
| Open-history groups | Not E2E; TLS in transit; messages stored in plaintext for shared backscroll |
| Communities | Not E2E; TLS in transit; messages stored in plaintext for history, mentions, and moderation |
| Broadcast channels | Not E2E; TLS in transit; posts stored in plaintext |
| Bots | Not E2E; Buzzio and the bot developer can receive text |
Shared-room media is stored as CDN bytes without at-rest encryption. Buzzio can read OHG, Community, and Broadcast content. There is no server-held DEK privacy model for those rooms.
Why the notice scrolls with content
The banner appears at the start of the conversation or feed and scrolls with history. It is a product disclosure, not a claim that TLS turns a shared room into end-to-end encryption.
