Unfortunately the current version of the software will not actively sync with outside calendars like Google. However you can certainly add your Cavanti calendar into your Google calendar, ie download your appointments into Google. To do this choose the time period you want to download in the Cavanti calendar (eg day), then click on iCal download at the bottom of the page. You can then go to your Google calendar and click on the gear icon in the top right, then settings>import. Select the iCal file you just generated in Cavanti and import it. All your appointments will now show in Google.
