You may disconnect your Google Apps calendar from Appointment.one at any time. Note that if you do not replace your Google Apps calendar with another calendar then Appointment.one will no longer function for your account.

There are two ways to disable Google Apps.

From Your Appointment.one Account

This disconnects the calendar and Appointment.one will remove its access keys. Note that with the approach the access keys themselves are still valid even though they no longer exist.

• Navigate to your Calendar settings under Account settings
• Click the Disconnect button next to your calendar

From Within Google Apps

This disables Appointment.one access to your Google Apps calendar by invalidating the access keys your created when originally connecting the calendar.

• Login to your Google Apps account

• Navigate to Settings -> Sign-in & Security -> Connected Apps & Sites

• Click on the Manage Apps button and find Appointment.one

  

• Click the Remove Button
