The trial period is well and truly free and without commitment. A valid payment method will be asked of you in order to confirm your country of origin and facilitate your subscription, but you will not be debited before the end of your free trial period.

Should you be unsatisfied with our service, it is possible for you to cancel at any time during this trial period, at no charge, and you can still enjoy this service until the end of the free trial period.

I haven’t found an answer to my question: contact our customer service team.
