Hey Danielle
Events Calendar Pro is exclusively a WordPress plugin. This means your events would be entered on your own self-hosted WordPress site.
You can see the features of pro in use at WP Shindig Demo Site https://wpshindig.com/events/. Do note, this has most all of our plugins installed and activated. The 2nd bar at the top is Filter Bar, and is an additional purchase. On single events you can save events to your personal Google Calendar. Likewise, you can see in the lower right of the month view how to export the whole calendar to your Google Calendar.
Events Calendar Pro does support recurring events and additional widgets and shortcodes.
Event Aggregator is our service that interacts with importing Google Calendar.
However, we’ve also just launched https://loxi.io/, which does not require WordPress to work. Check out a free account over there.
Is there anything else I can help you with?
Thanks
Courtney 🙂
