Hi Dan. Thanks for your question and your interest in our iCal Importer and other products.
iCal Importer is a powerful plugin that can receive feeds from Google Calendar or any other valid iCal feed. One of its most beneficial features is “scheduled imports” (e.g. import events from a specific iCal URL every 30 minutes).
If you’re simply looking for a way to one-time move from Google to your own site’s calendar powered by our suite of plugins, you could use an iCal to CSV converter (none are guaranteed but we’ve heard of some, e.g. https://www.gcal2excel.com) and then use our free CSV import functionality.
Even easier: we have a pretty great Refund Policy so you can buy one or many of our add-ons and thoroughly test them. Feel free to try a one-time import or scheduled import and see if it’s worth it to own it for the rest of the year or if it’s better to get the refund.
Let me know if you have any follow-up questions.
