I use privacy.com for some things where I'd rather not share my data with the vendor. I like them, their privacy policy doesn't have anything too weird. I'm also under no allusion that it's subpoena-proof though, but that's not really what I'm looking for for banking anyway.
EDIT: OP appears to be concerned with how they handle the PII they collect. As far as I know, I've never been impacted but tbh how would I know if they didn't tell me? If anyone has heard otherwise, I'd like to know.
