Very nice catch -- I checked and they do use media queries during print-to-pdf.

Saving the webpage itself works fine though -- which again, is a browser feature your secretary probably knows about and is comfortable using.

I guess my objection to the idea that this is just removing deniability is that it really doesn't feel to me like it's being marketed that way. I wouldn't call a service like this "confidential mode", I would call it something like "auto-delete mode". Maybe I'm just arguing over semantics though.
