# Licensing Questions

> Common questions about licensing, evaluation periods, and subscription models for Nextedy GANTT.

<AccordionGroup>
  <Accordion title="How long is the evaluation period?">
    The Gantt evaluation period is limited to 30 days from the date of installation. If you need additional time for evaluation, contact Nextedy support to request an extended time-limited license. Upon expiration, the software automatically disables itself until you obtain a valid license certificate.

    <Warning title="Evaluation expiry">
      The Gantt widget will stop functioning after the 30-day evaluation period. Plan your evaluation timeline accordingly and reach out for an extension before it expires.
    </Warning>
  </Accordion>

  <Accordion title="Can I extend my trial license beyond 30 days?">
    Yes, trial licenses can be extended beyond the initial 30-day period. Contact Nextedy support to request a continuation of your evaluation. This is useful when your team needs more time to complete the evaluation process or when procurement timelines are longer than expected.
  </Accordion>

  <Accordion title="What licensing model does Gantt use?">
    Gantt uses a subscription-based licensing model for new licenses. Perpetual licenses are available only as upgrades for existing customers. Edit access is controlled by the `nextedy_gantt_users` group -- members are Editors, everyone else has read-only Reviewer access (see [Licensing and User Access](/gantt/getting-started/licensing)).

    For the technical license-file types (Primary/Secondary Evaluation, Perpetual, Test) and their expiry behavior, see [License Types and Evaluation Periods](/gantt/reference/license-types).
  </Accordion>

  <Accordion title="Can I use my license on multiple Polarion server nodes?">
    Yes, licenses can be used on both nodes of a multi-node Polarion deployment. There is no restriction on deploying your Gantt license across clustered or high-availability Polarion server configurations.
  </Accordion>

  <Accordion title="What happens when my license expires or is invalid?">
    When the Gantt license is invalid or expired, a license status panel appears at the top of the Gantt widget with an appropriate message and contact information. The panel displays one of three states: valid (`ok`), approaching expiry (`warning`), or expired (`expired`). The license status is checked once at startup when the widget loads.
  </Accordion>

  <Accordion title="What is the difference between an expired license and expired maintenance?">
    An expired license prevents the Gantt widget from functioning entirely, displaying a license panel with contact information. Expired maintenance means your license is still active, but you are no longer entitled to software updates or new feature releases. You can continue using the currently installed version, but you cannot upgrade to newer versions until maintenance is renewed.
  </Accordion>

  <Accordion title="Where can I find the license administration settings?">
    You can access the Gantt administration settings by clicking the gear icon in the Gantt widget footer. This opens the administration page where you can view and manage license configuration. The Gantt version number is also displayed in the widget footer for reference.

    For complete licensing setup instructions, see [Licensing and User Access](/gantt/getting-started/licensing).
