You can cancel at anytime by going to your billing page (www.planoly.com/user/billing). Your subscription will cancel at the end of your billing cycle.
If you purchase on the app, this is handled entirely by Apple. You would need to go on iTunes to cancel your subscription. If you're on the app, go to my profile and click on cancel and we'll redirect you to iTunes.
Please keep in mind that cancellations on both Planoly and Apple will be for the next billing cycle. Planoly or iTunes cannot cancel mid-cycle. Please be advise that both Planoly and Apple have a no refund policy.
