Cannot remove Fantastical calendar from iMac

I tried the Fantastical calendar. Decent enough program, but they require a separate license for each of my four devices. I'm not a bout to pay $200 for a calendar that will work for everything. The problem is, now that this app is on my Launchpad I can't remove it.

I have moved it to TRASH but it just returns to the Launchpad when I release it in the TRASH.

How can I get rid of this?
