Privacy friendly bank account/payment method

Hi, I would like to find a bank or a privacy friendly payment method, not able to review every purchase I did.

I thought to several alternatives :

1° Find a bank explicitely dedicated to data privacy (names ?)

2° Open an account in a bank located in Switzerland as it's the world strongest regulation for data privacy ? 3° Use a masked card or virtual number card ?

4° Find a data privacy friendly online payment platform (name ?)

5° Use crypto or cash lol ?

Any advise about these options ? Would you recommend other options ? Also I'm located in Europe if you know specific offers in the EU market related to that concern.
