Résilier un abonnement annuel

For anyone else reading this
.
Please read everything so you know what you are doing BEFORE you buy a subscription or start a trial... the link below has the information you need
.

If you buy a HIGHER COST Monthly subscription you may cancel at any time without a fee... when you buy an Annual subscription with Monthly payments, and you do not cancel in NO MORE than 14 days from the start of your subscription, you pay 1/2 of the remaining time if you cancel early... you also need to keep track of your annual renewal date, so you may cancel after your 12th payment, before your subscription renews and you start a new one year subscription... RENEWAL IS AUTOMATIC UNTIL YOU CANCEL

or you can cancel.  make sure you're aware of the cancellation terms by selecting your plan type (at the top of the page here), https://helpx.adobe.com/manage-account/using/creative-cloud-subscription-terms.html

and for info on how to cancel your subscription, this page describes the few steps involved, https://helpx.adobe.com/manage-account/using/cancel-subscription.html

p.s. if you're contacted by anyone (via email or private message), it's much more likely to be a scammer than an adobe representative.

if you're unable to follow the steps described, check your account (https://account.adobe.com) for a payment problem. all payment problems must be resolved before cancellation is enabled, https://helpx.adobe.com/manage-account/kb/fix-failed-missed-payment.html
