Download NURO apk from other site than Google Play

Is it also possible to publish the .apk on github or another verified site of the urofoundation? Because I don't use Google Play, it is not on my phone (I use Cyanogenmod without Google account), so I cannot download from Google appstore. I know also that some devices (some cheap tablets, at least in Europe) were having Android but are not Google Playstore verified (so they were not having the Playstore at all) up till last year. Don't know if that is still the case, but it would help also for those devices if the apk could be downloaded elsewhere from a trustworthy site/account.
If the code is somewhere I will also be able to build it myself, but if not an .apk will do.
Would be great! Thanks!
