This licence policy is designed to allow maximum code reuse with the community of KDE and beyond while making exceptions for the few cases which need it.

All new source code and related data files in KDE repositories (SVN, Git) must meet the following requirements:

  1. All files must be in their preferred modifiable form, or alongside the file which is the preferred modifiable form. In the 'alongside' case, there must be clear instructions for how to build using the preferred modifiable form.
  2. All source files must contain a copyright header which identifies the copyright holder(s) together with an e-mail address that can be used to reach the copyright holder.
  3. Each source file must contain one of the licence headers listed below to state under which terms the software may be used, modified and redistributed.
  4. Source files that are part of a library with a public API which is part of the KDE Platform (kdelibs, kdepimlibs, kde-runtime and KDE Frameworks) must be licensed under:
    • LGPL version 2.1, or version 3 or later versions approved by the membership of KDE e.V.
    They may also be licensed under one of the following terms if it helps with license compatibility:
    Note: each bulletpoint above is a single option, it can not be licenced under just part of one bulletpoint option
    Note: code may not be copied from Qt into KDE Platform as Qt is LGPL 3 only which would prevent it being used under LGPL 2.1
    Note: the LGPL 2.1, 3 or approved by e.V. option is preferred and should be used unless there are special needs to improve code shareability
  5. Any other source files must be licensed under one of the terms listed under 4) or:
    • GPL version 2 or version 3 or later versions approved by the membership of KDE e.V.
    They may also be licensed under one of the following terms if it helps with license compatibility:
    • GPL version 2 or later
    • GPL version 3 or later
    • GPL version 3 or later versions approved by the membership of KDE e.V.
    • Code copied from Qt may be licenced under GPL version 2 or later versions or under GPL version 3 or later versions depending on the licence of the relevant Qt code
    Note: each bulletpoint above is a single option, it can not be licenced under just part of one bulletpoint option
    Note: where a KDE repository contains files which are GPL 3+ it must be clearly marked by adding the full licence in a file called COPYING.GPL3 in the top directory of the repository
    Note: Qt modules are either GPL2+ or GPL 3+, ensure the licence is compatible with your code before copying code from Qt
  6. Applications which are intended to be run on a server may be licenced under the GNU AGPL 3.0 or later
    Note: the GNU AGPL is the recommended licence for server software in KDE
  7. Translations of text from the files described in section 4 must be licenced under one of the terms in sections 4. Translations of text from other files must be licenced under one of the terms in sections 4 or 5.
  8. Media files such as images may be licensed under the CC-BY-SA-4.0 or compatible licence.
    Note: Image files must be committed together with their preferred modifiable form such as SVG.
    Note: CC-BY-SA 4.0 can be one-way converted to GPL 3.
  9. Icons should be licenced as CC-BY-SA 4.0 or can also be licenced under any of the terms in section 4 or 5 or 8. Icons in oxygen-icons and breeze-icons themes must be licenced under the LGPL 3 or later versions approved by KDE e.V.
  10. Content on collaborative edited websites such as wikis must be licensed under the Creative Commons Attribution-Sharealike 4.0 International or compatible licence.
  11. Documentation must be licensed under the CC-BY-SA-4.0 or compatible licence
    Note: CC-BY-SA 4.0 can be one-way converted to GPL 3.
  12. Documentation started before 2017 can be licensed under one of the following terms:
    • FDL versions 1.2 or later versions with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
    • FDL versions 1.2 or later versions approved by KDE e.V. with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
    Note each bulletpoint above is a single option, it can not be licenced under just part of one bulletpoint option
    Documentation may additionally be licensed under any of the terms in section 4 or 5.
  13. CMake modules must be licenced under the BSD licence listed below
  14. Windows installer files using the WiX Toolset may be licenced under the Common Public Licence 1.0
  15. Other data included in KDE's codebase must be licenced under one of the terms in sections 4 or 5.
  16. As new versions of GNU licenses are published they will be discussed by the membership of KDE e.V. and accepted via an announcement on https://ev.kde.org whether we will adopy it. This will depend on if adopting the licence would harm the future distribution of KDE, if the licence preserves freedom for our developers & users and a vote by the membership agrees to the acceptance of the new licence version.
