The Licence Details tab on the Global Settings page provides detailed information about your current license and its limitations.
The graph in this section of the page lets you track whether the number of active users and total disk space exceed the limitations for your license. Potential charges for overuse are shown above the graph, next to the current number of active users and used disk space.
If your YouTrack license has expired, click the Upgrade your subscription button to access the YouTrack website and purchase another license.
