Every paid plan starts with a 7-day free trial, and you are not charged if you cancel before it ends. After that, plans are billed monthly and you can cancel anytime; you keep paid features until the end of the period you paid for. If something went wrong (for example you were charged after cancelling, or the service didn't work for you), email ags.treefarm@gmail.com within 14 days of the charge for a full refund, no questions asked.
