How to uninstall Google App Store and Play Services on Intex Aqua Fish

Thanks for your response. I followed the approach of moving Google packages to the root directory:

devel-su
cd /opt/alien/system/priv-app
mv PrebuiltGmsCore.apk /root/
mv GoogleServicesFramework.apk /root/
mv Phonesky.apk /root/
mv GoogleLoginService.apk /root/

Afterwords I don't see the Google stuff any more in app Power Clean of the Jolla Store any more. If a user has updated this services with the default Android Store, the updates have to deleted there either.

Is it possible to remove the packages at the root folder now?

rm <file-names>

One additional note: Android starts very fast now and apps are working smoothly. It seems, that Google did grab a lot of data. It's always unbelievable, although I already know it, how comprehensive the surveillance of the big marked leaders like Google are and what a negative impact this has not only on lost privacy but also on user experience. I'm glad about alternatives to Apple and Google like Jolla. And their standard apps have that great user experience, that I almost need no further Android apps.
