# Sending, and the two keys at the door.

Nothing can be pushed onto your machine, files go straight across, and an internet session needs a key and a code sent by different routes.

Pull-only transfer

## Nobody can push a file onto your machine.

Privatta only moves a file when the recipient asks for it. The sender can offer a file — over the LAN or the internet — but there is no command path that lets them put a single byte on your machine unsolicited. This is the same rule everywhere, not a setting you can turn off.

- Every download is recipient-initiated, always
- Structurally blocks unsolicited or malicious delivery
- Applies identically on the LAN and over P2P

Direct transfer

## Drag a file in, send it straight across.

Drop any file into Privatta and share it in seconds. It travels directly to the other machine — no upload to a server, no link that lingers in someone's inbox, no copy left behind.

- Real-time transfer speed and progress
- Works for any file type or size
- No third-party storage, ever

Two-factor internet sessions

## The key and the code travel separately.

Sharing over the internet hands out two things: a 32-character connection key, and a 6-character security code generated on your machine that never passes through the relay. Send them by different routes — the key in chat, the code read out on a call — and an intercepted key on its own reaches a machine that will not answer. The host checks the code before credentials and before listing a single file.

- Both work once; the key expires in 5 minutes
- The code is checked before any file is listed
- Five wrong tries locks the session until you issue a new pair
