I am changing this review from a 5 star positive to 1 star because the developer has chosen to limit this app to the Play Store only. If you install it safely without wanting to be spied on by Crapoogle, you will get an error every time you launch the app saying "to continue using, get it on Google Play". I am absolutely shocked by this behavior. Disgusting! Guess I will look elsewhere for an alternative that truly respects my privacy instead of making false promises
