For proprietary applications (systems that don’t share source back to the community), +Mattermost is free to use and redistribute so long as you’re not withholding proprietary enhancements to the +Mattermost server and you’re only linking directly to or changing Admin Tools and Configuration Files (defined above), which +are released under an Apache 2.0 license, and copyleft free. + +We promise that we will not enforce the copyleft provisions in AGPL v3.0 against you if your application (a) does +not link to the Mattermost server directly, but exclusively uses the Mattermost Admin Tools and Configuration Files, +and (b) you have not modified, added to or adapted the source code of Mattermost in a way that results in the creation +of a “modified version” or “work based on” Mattermost as these terms are defined in the AGPL v3.0 license. + +If the above is not enough to satisfy your organization’s legal department (some will not approve GPL in any form), +commercial licenses are available from commercial@mattermost.com. + +MATTERMOST TRADEMARK GUIDELINES + +Your use of the mark Mattermost is subject to SpinPunch’s prior written approval and our organization’s Trademark +Standards of Use at http://www.mattermost.org/trademark-standards-of-use/.
