You can indeed, so long as you cancel it before the next charge period! Simply head over to www.skillshare.com using a desktop or mobile web browser in order to cancel your subscription - the steps to do so will differ depending on your payment method of choice.
If you used a PayPal account or credit card for your free train, you need to login and head over to Account Settings. Once there, hit the Payments button via the navigation menu on the left hand side, then click Cancel Membership and follow the on-screen instructions.
You’ll still have access to all of the Premium content until the “trial period” ends, even though you’ve cancelled it. It makes sense to cancel right away so you don’t forget and accidentally get charged!
When you signed up via the Google Play or iOS App Store, then unfortunately you cannot cancel, refund or manage your subscription via Skillshare. Android customers can cancel their free trial here, whilst iOS users should cancel it via this link instead.
Do be aware that your Skillshare account will remain active for as many days as your trial has left, allowing you to update any projects or participate in any discussions. As soon as the free period ends, however, you’ll lose access to everything - though you can return and regain it at any time.
