Broadcast channels
Broadcast channels are one-to-many publishing feeds — noticeboard / creator updates, not free-for-all group chat.
Privacy mode: Shared — server-managed encryption so feeds work across followers and devices.
Who can post
- Admins compose and publish.
- Followers receive updates and engage as allowed (for example emoji reactions).
- Followers do not post freely the way community members do in text channels.
Discovery
| Setting | Effect |
|---|---|
| Public ON | Channel can appear in search / discovery |
| Public OFF | Not openly listed; access follows share/follow path |
Encryption and retention
| Aspect | Detail |
|---|---|
| Text / captions | Server-managed encryption at rest (operate the feed; not sealed E2EE) |
| Media | Planned: Bunny CDN bytes + signed URLs; content-hash dedup within the channel (identical files share one object). Stories-style client media crypto is not used here. |
| Post retention | About 30 days, then removed |
| Reactions | May show anonymous tallies; server keeps enough uniqueness to limit spam voting — integrity, not ad profiling |
| Sold? | Never |
