Yikes.

This is part of the reason why I prefer to never let any services/apps/etc. save my bank/card details. If there’s not an option to save the card details that I can uncheck, 9x out of 10, I reconsider the transaction.

The assumption here though is that the services/apps/etc. that do provide the option actually respect it; in other words, unless you use fake/virtual card details (not entirely reliable, in my experience), you can’t be 100% sure that you’re safe either way, which sucks.
