Your files stay on this device
Cross-device and cross-network transfers need a signaling relay service that is planned but not yet available in this build — the shipped signaling only connects two tabs or windows of the same browser profile via BroadcastChannel, so you can use it for local testing but not yet to reach someone else's device. Only STUN is used for connectivity at launch: if either network sits behind a restrictive NAT or firewall that requires a TURN relay, the connection will not go through (TURN support is a separate privacy decision that has not been made yet). A transfer cannot resume after a dropped connection — if the data channel closes mid-transfer, you have to start over with a fresh code. No file is stored anywhere between the two peers: there is no persistent file server, so the sender's file exists only on the two devices that participate in the session.
How to use this tool
- Pick one or more files from your device and choose the Send side; a short-lived coordination code is generated for you.
- Enter that exact code on the Receive side in a second browser tab or window, and wait for the simultaneous-presence indicator to confirm the other side is in the session.
- Review the incoming file's type and size on the receiving side and accept the metadata confirmation before the transfer starts.
- Watch the per-chunk progress bar until the transfer finishes, wait for the SHA-256 hash check to pass, then save the verified received file.
