Deletes iCloud Calendars Permanently – Informant - Agenda, Tasks, Notes Planner Review

This has to be the worst app ever. It automatically synced with my iCal which is great. However, I didn't want to see some calendars I added or subscribed to so I deleted them from the app. Well, they deleted from iCal as well. I tried to restore and even logged into iCloud and my calendars were GONE!!! What kind of app does that!?
