What data does the mobile app creator see?

Question

Android

Hello. Became interesting. I logged into the Google account of the app store from my phone, linked my bank card, downloaded the application and made a purchase in it.

What data does the developer of the application in which I made a purchase see about me? Maybe the card number, the name of the owner?

Answer 1

First of all - no information that can personify you.
No card number, no full name, nothing like that.
As far as I know, in principle, he cannot really see anything, except for analytical data such as age and country, detailed information is stored by Google and he does not give it to anyone.

Answer 2

For example, I saw information about what city the user is from, age, what smartphone model and android version, when he entered the application and how much he was there.
There is no other information.
