Open-Source Notices
Published by Darwich Technologies LLC for StitchoMR (macOS 15 or later, Apple silicon; PES and DST export).
Effective date: October 30, 2026. Document set version: 2026-10-30-S15.
StitchoMR for macOS is proprietary software published by Darwich Technologies LLC. It includes open-source and other third-party components, each licensed under its own licence. Nothing in the StitchoMR End User License Agreement limits the rights those licences give you. This page is a notice. It is not one of the documents you agree to at checkout.
1. Where the notices and licence texts are
- In the application: Contents/Resources/third_party_licenses, inside the StitchoMR application bundle.
- On the web: the list of components, versions and licences is at https://stitchomr.com/open-source/third-party-notices. The full licence texts are in the application bundle folder named above.
2. Libraries under the GNU Lesser General Public License
- Qt 6.11.2, PySide6 6.11.2 and Shiboken6 6.11.2 are used under the GNU Lesser General Public License version 3 (LGPL-3.0). Qt is also available from The Qt Company under other licences; StitchoMR uses the LGPL-3.0 option.
- GEOS 3.14.1, used through Shapely, is used under the GNU Lesser General Public License version 2.1 (LGPL-2.1).
These libraries are separate, dynamically loaded files in the application bundle. We have not changed their source code. The binaries are the builds published by their projects, reduced to the Apple-silicon architecture. You may modify these libraries and run StitchoMR with your modified versions.

The source page at https://stitchomr.com/open-source/source/ lists these same upstream links and checksums. We do not host copies of the archives ourselves.
Our offer. You can download the source from the links above, or ask us for it in writing at support@stitchomr.com or by post to Darwich Technologies LLC, 4014 Medina Road #1159, Akron, OH 44333, United States, and we will send it by download link or on physical media for no more than the reasonable cost of the medium. This offer stays open for as long as the version you hold can be downloaded from us, and for at least three years after we last distribute that version.
4. Replacing the libraries
Step-by-step instructions for macOS on Apple silicon are at https://stitchomr.com/open-source/replace-libraries. They describe copying the application, replacing the library files, and re-signing your copy with your own signature. A copy you have modified is not an official build, our signature does not cover it, and we do not support it.
5. Other components
- Python 3.12 (Python Software Foundation License), including the notices of the libraries it embeds.
- PyInstaller 6.22 bootloader (GPL-2.0-or-later with a special exception that permits use in programs that are not open source). We use the project's prebuilt bootloader.
- NumPy, Shapely, Pillow, OpenCV 4.14.0, cryptography, cffi, pyembroidery, svgelements and defusedxml under their own permissive licences (BSD, MIT, Apache-2.0, PSF and similar). Each licence text is in the application bundle (Contents/Resources/third_party_licenses); the notices page above lists each component and its licence.
- A face-detector model file from the OpenCV project, redistributed unmodified under the licence reproduced in the notices.
- Country flag artwork in the design library, from flag-icons (MIT licence).
- The StitchoMR design library, icons, themes and brand artwork are original StitchoMR content and are not open source.
Open-source components are provided under their own licences, which disclaim warranties as those licences state.
