The Secure File Transfer web app works on Mac, Windows, Android, iOS and Chrome OS – anyone with a browser can accept your transfer. Add your own TURN server (Metered, Twilio, Xirsys or corporate) in settings for large file transfer without limits. Credentials are encrypted with AES-256-GCM. Custom TURN replaces the shared relay – no size quotas, advanced file transfer for power users. Q: Do I need to register? A: No. Open the page and you are ready. An anonymous device identity is created automatically – no email, no phone, no password. Q: Is there a size limit? A: No limit on p2p file sharing. The shared TURN relay has daily quotas, but add your own TURN server for unlimited P2P transfers. Q: Do both people need the extension? A: No. The recipient can open huskyhaul.online and enter the share code. Same secure file transfer, no install required. Q: What if a direct connection cannot be established? A: The transfer goes through our encrypted relay server automatically. The relay cannot read your data. Every transfer is a safe share, whether direct or relayed. Q: Does relay store my data? A: No. The relay passes encrypted packets. Nothing is stored, nothing is logged. Once done, there is no trace. Q: Does it work on Android and iOS? A: Yes. The web app works on any mobile browser. Use it for android file transfer – from phone to computer, computer to phone, or phone to phone. Q: Can multiple people download the same share? A: Yes. After one person finishes, the p2p file share goes back to active. The next recipient connects and downloads. Keep the page open to share file with everyone. Q: What if I need more relay capacity? A: Go to Settings and connect your own TURN server. Services like Metered.ca offer enough capacity for personal use – no size limits, no daily quotas. Install Secure File Transfer today and send files, share messages and links – all encrypted, P2P and without accounts. The simplest way to transfer files between any devices.
