What BunkerChat delivers.

01
256-Bit End-to-End Encryption

Every message is encrypted locally before it leaves your device. Keys are generated and stored exclusively on your device — the server never has access to them.

02
Bunker ID — No Identity Required

No name, no phone number, no email address. Your only identity is a self-chosen Bunker ID. You decide who you share it with.

03
Fake PIN and Automatic Wipe

Two PINs: a regular PIN opens the app, a second opens an empty decoy version. After three failed attempts, the app wipes itself completely and silently.

04
Direct P2P Connections

Calls and file transfers go directly between devices. No server as intermediary, no relay. Fully encrypted end-to-end with no third party in between.

05
Disappearing Messages

Messages are automatically deleted on both devices after a configurable time period. Duration ranges from 30 seconds to 24 hours.

06
Screenshot Protection

The operating system is instructed to prevent screenshots of the app entirely. The content of your conversations stays on your screen.

02 — Security

Your messages belong
exclusively
to you.

Even we cannot read your messages — that is technically impossible. If someone seizes our servers, there is nothing to find.

03
