## What is Kosmos Hi Lo?

Kosmos is a zero-knowledge messenger built so that your conversations belong to you — and only you.

Every message, call, and file is end-to-end encrypted. The encryption keys live on your devices, never on our servers, which means we can't read your messages even if we wanted to. No backdoors. No exceptions.

Why Kosmos

• End-to-end encrypted by default — Chats, calls, and shared files are encrypted before they ever leave your device. We can't read them, and neither can anyone else.

• Private communities — Build groups and spaces for your team, friends, or community, all encrypted by default.

• Everything in one private inbox — Messages, calls, and files together in a single secure place.

• No metadata mining — We don't build a profile on you. Add contacts by QR code with zero data collection.

• You hold the keys — Your identity and your conversations are yours. Recover your account with your own recovery phrase, not our servers.

Kosmos is for anyone who believes private communication should be the default, not a premium add-on. Download it and take your conversations back.
