Hi! There are many people, which do not use Google Play store, for security reason etc., in order to prevent spying!
It would be great to find a solution to install the App, without these spy tools,such as with F-droid Greetings

If you are using Android they already spy you. No worries. Installing from shop gives you warranty this app is from official NEM developer. Official store is the safest place to get app from Android/IOS.
