NET2017 builder

I’m updating our distribution channel detection and stumbled upon the NET2017 builder:

Can anyone tell me which distribution uses this?

FWIW our parsing here is a bit incomplete. I was surprised by the lack of “@” and looked at the raw reports – it’s actually NET2017\\Anwender@NET2017 (so a Windows builder, in German, or maybe something like Dutch as well, I don’t know) and the reporting devices are all Android.

Playstore or F-Droid?

Playstore and GitHub
