Aurora Store is safe and clean, there's no reason to be concerned about using it.
Although the code for it is good, in order to Aurora Store you must have your own individual Google account. The anonymous account has been rate limited because it was ierating as a shared account for all Aurora users, and Google can't data mine personal info when thousands of people are using one account.
You can install and update all apps that are in the Play Store through Aurora Store, but you must have your own account wirh the password to use Aurora Store.
In my view, I consider Aurora as being dead and gone. It's over, because I am not willing to create a Google account.
