Monthly billing option?

I have reached the end of my free trial and I need to select a plan, however, I am confused by the plan options. I am looking for a month to month plan because I don't use the product consistently, only when traveling. However, I don't see a monthly option. I only see an annual option with a monthly billing. I don't want an annual plan. If I select the annual plan with a monthly billing option, can I cancel the plan after a month or two without paying any cancellation fees?
