Your subscription starts on the day of your order, and lasts for exactly one month (that is: one day before the same day of the next month, e.g. 15th of July to 14th of August, or 15th of August to 14th of September).
Your subscription will automatically continue for another month if not cancelled on time. To cancel your subscription by the end of the current subscription period, a cancellation has to be issued one (1) week before the end of the running period.
