How to unlink a calendar you no longer need

You can stop a calendar from appearing in two ways: by turning off calendar syncing for that account in your device settings, or by hiding it in Simple Calendar. Note that the two have different effects.

Change the device settings

1. Open the "Settings" app on your device
2. Tap "Apps" → "Calendar" → "Calendar Accounts"
3. Tap the account you no longer want to link
4. Turn off "Calendars"

Change only the settings in Simple Calendar

1. Open Settings in Simple Calendar
2. Under "Display Settings", uncheck the calendars you don't want to show
