Is there a secure (password protected) stand-alone calendar for the iphone 5? I use the calendar that comes with the device for home appt, which I sync to iCloud. However, I want to have a secure (non-sync) calendar that I can use to record upcoming patient appointments for my clinic. The two requirements I have are: (1) it has a second level of password protection. The iphone is pass code protected already. (2) I can disable syncing with cloud-based calendars. I don't want the patient information to be distributed in any way outside of the device. Does such a calendar exist?
