Upon initial purchase of Gliffy Diagrams for Confluence or JIRA (server version), maintenance & support runs for a year from purchase date. During this time, you will have access to all of our updates and new releases.
Once your license has expired and you do not renew, you will no longer have access to any new updates/releases. You will however retain full functionality of the Gliffy plugin version you are running after expiration. However, functionality may change or Gliffy may stop working properly depending if your Gliffy version is no longer supported by us or if your Gliffy version is no longer compatible with your Confluence version.
