As far as I understand, chain delegation from Bitkey enables you to be quite private if you know how to set it up (use your own node, disable certain notifications, etc.).
Besides that, in case they have to co-sign, they are able to see this particular transaction (which they claim not to log and want to proof somehow in the future).
Definitely a big upgrade compared to Nunchuk, Casa, etc., which as far as I understand so far can see your whole balance, all movements at any time. I definitely can see many problems in this approach.
So in short, if someone asks Bitkey about your total balance, even if they wanted to, they simply can't tell, while the same for Casa and Nunchuk looks completely different, as they always see your full balance/history, like your bank would.
But maybe I get this wrong? But hard to tell as I wasn't able to find that kind of information in their FAQs etc.
