Aurora Store is an app store being developed and updated regularly by Rahul Kumar Patel. In this fork of Yalp Store, you'll be able to download any application you want while maintaining your privacy.
The number of applications that are available on the Google Play store can be great but you might be concerned about your privacy while using it. You probably should be concerned about your privacy due to how they have regulated their services in the past which is why Aurora Store has come along. Built as a mirror of the Google Play Store, you instantly get access to every single application available on that store without having to create an account. This means that you not only don't have to worry about your privacy being overtaken by Google but by anyone else that could have grabbed your account details.
Overall, Aurora Store is one of the best app stores available on the market given that it still has all the same applications the Google Play store has. Depending on the application to use, you'll only have to worry about some applications still requiring a Google account due to needing Google Play Services on your phone.
