Thank you for the question.
I don't know the internal processes of financial institutions. That said, usually, when information is provided in this way, it's for a very specific reason. If the information is used for any other purpose, usually that's unacceptable and not something that financial institutions would do.
I don't work in a financial institution, so I don't know the internal processes. However, I can tell you that the plan was to use the information for a very specific purpose and for a very limited time.
