Is there a minimum contract length?

No! When you book a plan, you pay for the use of PollUnit in advance. Depending on the period you choose, this can be one month, 6 months or one year. With a one-time payment, your package simply expires after the selected period. If you choose a subscription, you can cancel it any time before the next booking free of charge. You then keep the functions of your plan until your booked package has expired.
