Ionic App ngCordova SQLite Plugin: How to ensure that database is created

I am following this article:

And I create the db using the following lines of code:

db = $cordovaSQLite.openDB("my.db");

Now I want to see where in Ionic app the database has been created. I am testing it in the browser, iPhone simulator and physical device but I don't know where to look in either scenarios for the physical my.db file.
