collects userdata and installs advertising channel.
Akpure offers many apps, also some of which google play store doesn't. On the other hand it installs, without telling it, a advertising subchannel which begins to advertise after some time. This advertising raises more and more, first only on use with the app itself, later with the use of some apps that were installed with apkpure, and finally with most other apps too, even with the play store app. It then gets recognized as 'bad app' from play store, and I think, that's ok. I finally uninstalled the app myself. There are other stores like e.g. F-Droid that do not install a adv-channel and won't advertised. Evevthough, keep in mind, also playstore does collect user data and usage information! I have deactivated playstore at least and activate it only if I update some Google apps.
