Data in SharedPrefences is saved until the user uninstalls the app, or clears the app cache

Data in SharedPrefences is saved as file in your app internal storage, its be removed in case:

unInstall app
clear you app data
call yourSharedPreferences.edit().clear().apply()

When you clear the cash memory form settings all the information will be deleted and start fully new. so it not exactly that you need to uninstall your app.

So sharedpreferences is basically store data in primitive way which mean it doesn't contain data directly instead it's reference.
