Darkboard Prime — Third-Party Notices
Darkboard Prime is © 2026 Ricardo Curtis and is licensed under its own licence agreement (EULA.md). It includes the open-source libraries below. Each stays under its own licence, and nothing in the Darkboard Prime licence limits your rights under them.
Qt 6.12 (LGPL-3.0)
Qt Core, Gui, Quick, Qml, Quick Controls, Quick Dialogs, Quick Layouts, Quick Effects, Quick Shapes, Quick Vector Image, Concurrent, Multimedia, Svg, Sql, Network, DBus, OpenGL, Widgets and Labs modules. © The Qt Company Ltd and other contributors. Used under the GNU Lesser General Public License v3 (licenses/LGPL-3.0.txt, which builds on licenses/GPL-3.0.txt).
- Dynamic linking: Qt ships as separate frameworks inside the app (
Darkboard Prime.app/Contents/Frameworks/Qt*.framework). You may replace them with your own compatible build of Qt 6.12 (the app's code signature then has to be re-applied withcodesign --force --deep --sign - "Darkboard Prime.app"). - Source: https://download.qt.io/official_releases/qt/6.12/ . Or ask: Ricardo Curtis, darkboardprime@gmail.com, and I'll send the exact Qt source used, for up to three years after this release.
- Unmodified: Darkboard Prime uses Qt unmodified.
