WinSCP Headquarters and/or USA Offices

I recommended to a small Bank in Kansas, USA, to use your WinSCP product for FTP file transfers, and they asked me where are you located.

Are you located in the United States or have offices here? Or are you located in Europe?

Thank you,

Jeff

WinSCP is an open source project. There's no company behind it. No offices. I'm located in Europe (in Prague).
