Android/iOS Persistent Data Storage

I'm trying to understand how applications are storing data without the use of a login system. Example, an android app starts you with 500 coins and you use some of them. You have not logged in at all and you delete the 'app data' in settings and uninstall and reinstall. The app still knows you only have 450 coins left for example. The app requires internet connection so I'm assuming they are storing the info on their server. If so, how are they uniquely identifying your device? In my reading so far it seems there is no full-proof way to uniquely identify a device every time. I'm asking because I'm going to be working on an app where I don't want to require a login but I also don't want the player to simply reinstall and get to start over. So, my question is how does everyone handle this situation to work for both iOS and android?

Google offers Firebase, which is used for notifications, but makes use of a unique identifier for an application instance on a device (both on iOS and Android), they could be using this.

There are some more providers that offer a similar service (for example OneSignal).
