# QR Code File Transfer

> Private device-to-device file transfer that never touches a server. Your file becomes an animated QR code stream on one screen and is rebuilt by the other device’s camera — nothing uploaded, nothing stored, no account, no app. Free, open source, works with every radio off.

Free and open source (MIT). No server, no upload, no account, no telemetry. Both roles are a single web page that works fully offline after one load.
