Hi Mike,
Thanks for posting 🙂
The iCal standard doesn’t really have a notion of public and private – rather, everything in a given iCal feed is generally seen as being available for consumption (by our importer, in this case).
The answer to your question then probably lies in the way you have configured your events on Google Calendar and upon the actual iCal URL you are sharing.
However, as this is the pre-sales forum, it’s not the right place to go into technical detail. If you need further help can I ask that you login and post in our iCal Importer forum instead?
Thanks again!
