iPhone X How come after deleting an App, and you reinstall it, it still "remembers you"?

I am having trouble with the LevelUp app, particularly with adding the "card" to my Apple Wallet. I have tried everything, but it keeps saying "An error occurred while trying to add this pass to Apple Wallet" or something along the lines of that. So I did what any other person should be doing, which is delete the app, and then reinstall the app. Lo and behold, it doesn't even ask me to login, it just remembered who I was, ....of course with the same error message.

Maybe data is stored on the iCloud, you can see that in iCloud Disk settings.
I remember seeing this as an added feature for an iCloud update once - app data are saved in iCloud so you can reinstall an app and not have to go through setting it up all over again.

You can delete data for certain apps in:
Settings > Tap your name at the top of the Settings page > iCloud > Manage Storage > Backups > iPhone name > Turn off data for a chosen app to delete the data and avoid future backups.

@dontwalkhand This is likely why your login is saved for an app that you deleted and reinstalled.

Could be cache or some verification token as well. Try to log out > delete > reinstall > log in again.

p.s. Make sure you remember log/pass/2FA for this app and that log out won't mess up anything!
