Privacy Statement

Last updated: 28 July 2026

Zeig hands a photo or file from one device to another. It was built so that nobody — including us — can see what you hand over.

What we never see

Your files travel directly between the two devices over an encrypted peer-to-peer connection. They are end-to-end encrypted with a key that exists only inside the QR code the sender shows and the device that scans it. The key travels in the link's fragment (the part after #), which browsers never send to any server. No file, file name, file size, or key ever reaches our infrastructure.

What our server does

To find each other, the two devices briefly exchange connection details through a small relay at zeig.franzai.com. The relay sees only an opaque room identifier and the connection handshake. It stores nothing: rooms live in memory for at most five minutes, hold at most two participants, and evaporate when the transfer starts or the participants leave.

What we collect

Nothing. No accounts, no analytics, no cookies, no tracking, no logs of who transferred what to whom. The app asks for camera access only to scan the other phone's code, and photo library access only so you can pick what to send. Neither leaves your device.
