[Diane] “How do I remove iCal calendars from SmartDay without deleting all of the ical calendars from my computer?  I don’t want to delete them in case I need them for reference.”

SmartDay (for Mac) automatically connects with all iCal calendars. So you have two choices: (1) Remove them from iCal (easy to do) or Hide them in SDM (use the ‘eyeball’ icon at the bottom).

For SmartDay iPhone and SmartPad, you do not need to sync with your device Calendar.
