Noob question about contracts

Hello I started learning about contracts and deployed my first test contract for a token on the test net.

I cannot find anything explained about this, so i try to ask here:

  1. all the examples I find of contracts are creating a new token (a crypto coin) with a name, symbol and supply. Is it possible to use contracts to store information on the blockchain with already existing crypto token and search for this information afterwards without creating a new token? And how, are there any tutorial about this?
    I don't need NFT, just i am looking for a way to store some numbers on the blockchain and a date field for each user like a database to be retrieved later.

Thank you

I'm pretty sure that's use case. If you don't want to build anything you can check over there
