To create your first Virto Calendar, choose **My calendar**, **Advanced settings**, or start from a **template**.

Choose **My calendar** to build Virto Calendar from your Outlook calendar. Or select **Advanced settings** for more configuration, or start from a **template**. You can, for example, connect a SharePoint calendar as the data source. If no SharePoint calendars are available on your site, you’ll see **No calendars existing.** In that case, add one or more Outlook calendars from the list. When you’re done, click **Create** or **Use Template**.

VirtoSoftware does not retain your data. Permissions are used solely to render overlaid calendars in real time for the user who opens the Virto Calendar app. Access applies only while that user is working in Virto Calendar. Each session generates a unique private key that is never reused—every new session creates a new key.
