================================================================================ SimpliTake — Third-Party Software Notices Copyright (c) SimpliTake LLC. All rights reserved. ================================================================================ Contact: INFO@simplitake.com Also see: THIRD-PARTY-LICENSES.txt (structured component list) and the full license texts in the "licenses" folder. -------------------------------------------------------------------------------- WHAT THIS DOCUMENT IS -------------------------------------------------------------------------------- SimpliTake is commercial, proprietary software owned by SimpliTake LLC. You license SimpliTake under our User Agreement (EULA) — SimpliTake is NOT free or open-source software, and it is a one-time purchase with no subscription. Like many desktop programs, SimpliTake also includes some free, open-source components (for example, the toolkit that draws windows and buttons, and libraries that read and write PDF and Excel files). This document credits those components, explains your rights for the open-source parts, and points you to their full license texts. You do not need to read this file to use SimpliTake for everyday takeoff work. -------------------------------------------------------------------------------- WHERE TO FIND LICENSE FILES (after installation, next to SimpliTake.exe) -------------------------------------------------------------------------------- THIRD_PARTY_NOTICES.txt (this file — plain-language summary) THIRD-PARTY-LICENSES.txt (structured list of bundled components) licenses\ (full legal license texts) README.txt LGPL-3.0.txt (PySide6 / Qt — see Part 1) LGPL-2.1.txt (GEOS geometry library via Shapely — see Part 2) MIT.txt, Apache-2.0.txt, BSD-3-Clause.txt ================================================================================ PART 1 — THE UI TOOLKIT (PySide6 / Qt) [LGPL v3] ================================================================================ SimpliTake's screens, buttons, and dialogs are built with Qt technology, delivered as PySide6 (Qt for Python) on Windows. Qt is produced by The Qt Company and others and is licensed under the GNU Lesser General Public License, version 3 (LGPL-3.0). What that means for you: • SimpliTake itself remains proprietary — you may not copy or resell SimpliTake's own code. • The Qt/PySide6 files shipped with SimpliTake are open-source under the LGPL. • You may keep using SimpliTake normally. • The LGPL grants certain rights for those Qt-related files only, including the right to obtain their source code and to replace those library files with a compatible LGPL version (advanced; optional). Please do not delete or alter copyright or license notices in the install folder. HOW TO REQUEST LGPL SOURCE CODE We will provide source for the LGPL-covered parts (PySide6, shiboken6, Qt 6, and/or GEOS via Shapely) for at least three years after we last provided this version. To: INFO@simplitake.com Subject: LGPL Source Request Include: product name (SimpliTake), your version, approximate purchase date. Official upstream sources (often quickest): https://code.qt.io/cgit/pyside/pyside-setup.git/ https://www.qt.io/download-open-source Full LGPL texts: licenses\LGPL-3.0.txt and licenses\LGPL-2.1.txt ================================================================================ PART 2 — OTHER OPEN-SOURCE COMPONENTS IN SIMPLITAKE ================================================================================ These libraries help SimpliTake open PDFs, show page thumbnails, export to PDF or Excel, and compute area-takeoff geometry.
