SOVEREIGN MESSAGING · E2EE · SERVERLESS · OFF-GRID

There is
no middle.

Messages nobody in between can read, scan, or block — because nobody is in between. No servers, no accounts, no company. Works over the internet, €30 LoRa radios, or a USB stick in a pocket.

THE DOCTRINE — FOUR PRINCIPLES

No one in the middle

Peers talk directly, via volunteer relays holding only sealed ciphertext, or over radio. There is no checkpoint where scanning can be mandated — by architecture, not by policy.

State-of-the-art cryptography

Hybrid post-quantum key agreement (X25519 + ML-KEM-768), Double Ratchet with encrypted headers, XChaCha20-Poly1305 everywhere. Published, audited designs only — no invented primitives.

Off-grid is first-class

When networks are shut off, the same sealed messages ride commodity Meshtastic LoRa radios — kilometres of range, multi-hop, ~€30 hardware — or local links, or file/QR sneakernet.

Your keys, your data

Identity is a keypair you mint yourself — no phone number, no email. History is stored locally, encrypted, exportable, and deletable for real.

ONE SEALED ENVELOPE — FOUR WAYS HOME

ONE ENVELOPE, EVERY CARRIER

Internet — libp2p · QUIC · DHT · relay v2 · hole punching

GLOBAL · MS

LAN — mDNS discovery, direct QUIC on shared Wi-Fi

SITE · MS

BLE — phone-to-phone, no infrastructure at all

~100 M · S

LoRa Mesh — stock Meshtastic radios, multi-hop, ~€30

KM–100 KM · S–H

Sneakernet — sealed .kkb bundles on USB sticks or QR

Honest limits.

No honest tool claims to protect everything. Our threat model documents what KommsKult cannot do as carefully as what it can.

IT PROTECTS

— The content of your messages, against anyone in between
— Recorded-today ciphertext against future quantum computers
— Your history on a lost or stolen locked device
— Your ability to communicate during internet shutdowns

IT CANNOT PROTECT

— A phone that is already hacked or seized unlocked
— The physical fact that a radio transmitted
— You, if your contact shares your messages
— Anonymity against a global passive adversary (yet)

STATUS — MILESTONE M2 OF M6

M0–M2 ✓ — design framework, crypto core, protocol & encrypted storage: built and tested

M3–M4 — internet transport, headless node, Meshtastic bridge

M5–M6 — desktop + mobile apps, external security audit, stores

Why now? The EU's ChatControl regime mandates scanning at the service provider. KommsKult's answer is architectural: you cannot order a checkpoint installed where no intermediary exists.
