Sync for YNAB – Connecting YNAB to UK Banks

Would be really handy but I'd definitely want a page on the site spelling out in explicit detail how data flows and who has access to what plus what happens if things go wrong.

Not that I assume shenanigans but if I'm giving someone access to my bank account, even read-only, I want to be damn sure it's safe and that I'm covered if things go wrong.
