If it is a free trial, why are the credit card details required?
The IDrive free
trial allows you to evaluate our online backup, storage and
sharing service.
Your credit card details are collected to give you a
hassle-free transition to an IDrive paid subscriber, which
means that once you have completed your free trial, you can
continue using the service without any interruption.
In case, you do not cancel your account within the trial
period, your credit card will be billed on a monthly basis at
the end of free trial period.
