ensuring my "annual" ExportPDF subscription doesn't renew... ?????

I needed Adobe ExportPDF for one thing in class, almost a year ago, and I saw that it was an annual subscription.  So I put on my calendar on June 10th that I needed to somehow verify that my subscription was cancelled.  I haven't used it in 10 months or so and I'll never use it again.  How oh how, dear community, can I ensure I'm no longer in a recurring subscription please?

THANK YOU, THANK YOU, THANK YOU!
