📋 What is AirDows?

AirDows enables you to send files from your browser to any nearby device. Pairing is instant via QR code or 4-digit code. Files are transferred at original quality without compression and are never permanently stored.

When network conditions allow, AirDows attempts to establish a direct peer-to-peer (P2P) connection using WebRTC. If direct connection is not possible, encrypted traffic may pass temporarily through a TURN relay server as a fallback.

The effective file size depends on your browser, device, available storage, network stability, and the connection path between devices.

🔐 How AirDows Transfers Your Files

AirDows attempts to route your files directly between devices using WebRTC. When that's not possible due to network restrictions (corporate firewalls, carrier-grade NAT, etc.), encrypted traffic may temporarily route through a TURN relay server.

Important: Transfers are encrypted in transit. Files are not permanently stored on any server and are deleted immediately after successful transfer.
