Our free plan is available on all new accounts. Optimal Workshop tools are all available on a free plan which you are able to use to trial all major features before you upgrade to a paid subscription. Additionally, even after your paid subscription ends you will still be able to access all your studies and the participant responses including the Optimal Workshop analysis tools and visualizations, for free.
By default, when you purchase a subscription with Optimal Workshop it will automatically renew at the time of expiry. You will see the following highlighted notice before submitting payment:
As the notice says, "You can cancel automatic renewal at any time from the My Plans tab on the My Account page."
Once you cancel automatic subscription renewal you won't be charged again, but you are responsible for whatever charges have already been incurred. For example, if your renewal is due on the 18th of July and you cancel on the 24th, your payment will have already gone through but you won't be charged again after that. In order to treat everyone equally, no exceptions will be made.
How do I cancel automatic subscription renewal? You can cancel your subscription at any time by logging into your account and selecting the "My Account" tab near the top of the page. Once you are on the My Account page, select the "My Plans" tab and then click "Cancel automatic renewal for [tool]", as shown below:
