AirBridge is a peer-to-peer file-transfer tool. The short version: your files never touch our servers, we do not run analytics, we do not set advertising cookies, and we do not have accounts or profiles to leak. This page goes into the detail.
What AirBridge does not collect
- Your files. File bytes flow peer-to-peer over an encrypted WebRTC DataChannel. AirBridge cannot read, mirror, log, or recover them — they exist only on the two devices involved.
- Accounts, emails, passwords. There is no sign-up. We keep no user database.
- Behavioural analytics, ad identifiers. We do not embed Google Analytics, Meta Pixel, Mixpanel, or any similar service.
What briefly passes through a signaling server
To discover each other, the two browsers exchange a small amount of WebRTC metadata — a session-description and a few ICE (network) candidates — over a public signaling relay. This exchange contains:
- The random room code you share.
- Your device's public IP and candidate NAT addresses, which WebRTC needs to route the direct connection.
- A one-off cryptographic fingerprint that the browsers use to verify each other.
No file content is transmitted through the signaling server. Once the two browsers have enough information to talk directly, the signaling server stops being part of the conversation.
Hosting and logs
AirBridge is hosted on Vercel. Vercel keeps standard web-server request logs (timestamp, URL, user-agent, IP) for operational and abuse- prevention purposes, as described in Vercel's privacy policy. We do not read, retain, or augment these logs ourselves.
Browser storage
AirBridge does not use cookies. It may briefly store in-memory state during a transfer (the room code, the file name, the bytes being assembled by the receiver) — all of this is discarded the moment you close the tab.
Children
AirBridge is not directed at children under 13. Because we collect no personal data, we have nothing to hand back to a parent or guardian and nothing to delete on request.
