When you make a purchase you'll receive a license key in an email. This key entitles you to run one instance of a JumpBox virtual machine. The key will also enable the restricted features of the JumpBox runtime, this includes the JumpBox Backup System, the ability to turn on SSH access and the ability to remove the JumpBox navigation bar. It also allows you to move from an older version of the JumpBox to a newer version. With your purchase you'll have access to new versions of the JumpBox for one year.
