Block, report, and stay safe
Safety tools reduce abuse. They are not a substitute for sealed cryptography, and they create limited operational records by design.
Block
- Open the contact / chat info for that person.
- Choose Block (wording may vary slightly by screen).
- Manage the list later under blocked accounts in settings.
Effect (typical): sealed delivery and calling through that private relationship should fail at the gate when certificate-gated delivery enforces the block. You should not keep getting that person’s 1:1 messages or calls.
Unblock from the blocked list when you intend to allow contact again.
Report
- Open contact / chat info → Report.
- Pick a reason when prompted.
- Submit.
Reports create safety records so Buzzio can investigate abuse. That is operational data — see What Buzzio can see and Threat model. Do not include your recovery phrase in report text or screenshots.
In-chat privacy tools (device residue)
These reduce what remains on phones after decrypt. They do not make a malicious peer unable to copy content by other means.
| Tool | Role |
|---|---|
| Secure View | Mutual screenshot / recording hardening while active |
| Vanish | Short TTL after seen |
| Disappearing messages | Chat-level 24h / 7d / 90d |
| Once-view / view-once | Stronger leave-after-seen behavior |

Harassment and spam
- Prefer block first for private relationships.
- Use report for scams, impersonation, or severe abuse.
- Free-tier rate limits and App Check reduce bulk spam; see Premium and quotas.
- Community / channel admins use role and moderation tools on shared surfaces.
