Even if your bank doesn’t do it, the credit card processor will. They will be very careful to “anonymize” the data up to a legally plausible deniability level, just like Google does, before selling it, but that’s about it. Even if you use multiple banks with multiple credit cards with different card processors, someone purchasing enough of the “anonymized” data would be able to correlate some of it.
If you don’t want (almost) any data to be scraped, it’s either cash or Monero.
However… if you have no credit history, don’t expect to get any loans, so you might want to build a history of being a reliable fool good client.
