No. Cloudflare relays encrypted connection metadata only. File content travels through a WebRTC DataChannel and is not stored by UUUP.
This tool uses free STUN-assisted direct connections and no TURN relay. Restrictive corporate, campus, or carrier networks may block P2P connectivity.
The streaming desktop path supports up to 10 GB per file and 20 GB per batch. Browsers without direct disk writing use lower limits.
