# How Knit works, in plain words

> What your phone is doing when it passes a message along, written for people who don't build radios for a living.

Each page answers one question, short answer first. The end of every page says where the feature stops, so you know what to expect before you rely on it.

## How messages travel

From your phone to someone else's, one hop at a time.

- [How a message reaches someone who isn't in range yet](https://getknit.app/docs/store-and-forward/index.md): How phones hold on to a message and hand it to the next phone they meet, and why some messages arrive late.

## The radios

Bluetooth, Wi-Fi Aware, and what each one is good at.

- [How Knit uses Bluetooth and Wi-Fi Aware](https://getknit.app/docs/bluetooth-and-wifi-aware/index.md): Why Knit runs two radios at once, what each one is good at, and what Android asks you for.

## Privacy

What stays sealed, and who can see the rest.

- [What Knit encrypts, and what stays visible](https://getknit.app/docs/encryption/index.md): What end-to-end encryption covers in direct and group chats, what stays visible, and how to verify a contact.
