If you don't see this text, you don't have an Academia Premium subscription. If you were charged for an Academia Premium subscription, but you don't see the Premium Subscription sidebar, please contact us immediately and we'll sort it out for you. Providing the last four digits and expiration date of the card you paid with will be helpful.
If you do see your Premium Subscription settings, click there. Then, click the big red "Unsubscribe" button.
Please select a reason why you are cancelling your Academia Premium subscription or any other feedback you might have, then click the red "unsubscribe" button again.
Your subscription will then be cancelled and your Premium Subscription page will change to show the last date that you have Academia Premium benefits. What this means is that after your current Academia Premium subscription period, your benefits will lapse, and you won't be charged again. This does not mean you will be refunded. If you would like a refund, please contact us within 30 days of the day you subscribed.
