BÁKN // OLD NORSE: A BEACON. A SIGNAL LIT WHEN ALL ELSE FAILS.

The message
gets through.

Bákn is a secure, cross-platform messenger that keeps people connected even when the network doesn't cooperate. Wi‑Fi down? Cell tower gone? Your messages relay phone‑to‑phone until they land.

01 // CAPABILITIES

Everything a messenger should do. Then it keeps going.

RT-01 / CHAT

Real-time chat

Channels and direct conversations with typing indicators, replies, edits, and delivery status — all live over WebSocket.

AV-02 / CALLS

Voice & video calling

Built-in WebRTC calls with camera and mic controls, plus screen sharing. No plugins, no third-party bridge.

FS-03 / FILES

File & image sharing

Drag-and-drop photos, docs, and PDFs with inline previews. Every upload is malware-scanned, capped at 25 MB.

BM-04 / MESH

Works offline, keeps working

Server gone? Bákn relays messages phone-to-phone over Bluetooth mesh until the connection is restored.

XP-05 / NATIVE

True cross-platform

One app, built with .NET MAUI, running natively on Windows, Android, iOS, and macOS.

RC-06 / RESILIENT

Smart reconnection

Sessions persist across restarts, tokens auto-refresh, and network flaps never cost you a message.

02 // THE DIFFERENCE

The network died.
Nobody noticed.

When the server connection drops, Bákn falls back to a Bluetooth mesh network — relaying messages phone‑to‑phone until a connection is restored. Festivals, disasters, dead zones, blackouts: the conversation keeps moving.

> No other consumer chat app does this.

03 // SECURITY-FIRST

Locked down by default.

End-to-end signed messages — every message is cryptographically signed; tampering is detectable, impersonation isn't possible.

Encrypted local storage — your history is encrypted at rest on every device.

Content-type validation — every upload is verified against its declared type before it touches a chat.

Audited file access — every file open is logged and reviewable.

04 // ONE APP, EVERY DEVICE

Natively everywhere.

One codebase built on .NET MAUI, compiled native for every platform you own. Same account, same history, same mesh — desk to pocket.
