I think "secure" and "cloud" are pretty misleading. In terms of security (if it's about my personal mail/calendar) my bigger concern would be that my data is lost, e.g. not backed up properly, deceptible to hardware failures. As for "cloud" - I can't see much on the page that would have remotely the same properties as a "cloud" solution. Maybe that's why they put it in quotation marks? Still, very misleading imho.
