What database to use for an online Android game?

Question

Android

Hello.
I immediately apologize if the question sounds stupid or I myself am talking nonsense, since I do not know how all this is implemented.

There will be an Android game. It contains information:
Information about the user (login, password, etc.);
Game data of the user (coins, lives, experience, etc.);
Some general data, such as a "promo code".

So, the question is: how and where can I store all this information online so that only I, as an admin, have access to this information and the game refers to this information? So that no one can hack into this data.

1. Software on my computer, and its info is stored on the server?
2. An Excel or Access file that is stored in the cloud?

Or is everything that he wrote - nonsense, and should it be somehow different?

Thanks in advance.

You can use any database - MS SQL, mySQL, PostgresQL, Redis, MongoDB, MariaDB,... On any VPS/VDS.
Or Parse https://aws.amazon.com/marketplace/pp/B01BLQ17TO
No Excel and Access!!!
