My brother stuck the aptoide store on my nephews Nvidia shield android device. I tried adding Net Monitor from them & got, what appeared to be, a weird modified, not very functional version. After I got fdroid running and the proper Net Monitor I found Aptoid app was making connections to Facebook & other stuff that looked shady... https://f-droid.org/app/org.secuso.privacyfriendlynetmonitor
I'd recommend Aurora store from Fdroid if you need apps not on Fdroid
