Open Source Software Notice
Product
Q Display (Q Experience product family)
Manufacturer
Nextfour Group Oy
This product contains open source software. Please refer to the license texts included below for the terms and conditions of their use.
How to Obtain Source Code
The complete source code for all GPL, LGPL, and other copyleft-licensed software in this product is available free of charge. To obtain it:
Send a request to q-support@nextfour.com with the subject line "Q Display Source Code Request" and include:
Your product model and serial number (if applicable)
Software version (found in Info → About)
We will respond within 10 business days with download instructions or physical media options.
The source code package is provided at no charge or for a fee not exceeding the cost of physical distribution. The package includes:
All GPL and LGPL component sources
Build scripts, toolchain specifications, and compilation instructions
All modifications and patches applied to the original sources
Installation procedures for modified software
This offer is valid for three years from product distribution and is available to any third party.
Note
Some packages offer multiple license options (e.g., "GPL-2.0 or BSD-3-Clause"). Where available, we operate under the more permissive license option. Users redistributing these packages may choose either option as specified by the upstream project.
Security and use of modified software
The Q Display is designed to comply fully with open source license obligations under GPL and LGPL. To enable users to exercise their rights to modify and replace open source components, the device provides a mechanism for installation of user-modified libraries and executables through the procedures documented in the source code package.
However, once user-modified software is installed the security model of the device fundamentally changes. The system can no longer guarantee the integrity and trustworthiness of the software environment. For this reason, when users install modified software, all confidential credentials including private keys, client certificates, and authentication tokens are automatically removed to protect the integrity of Q Experience backend services.
As a result, a device running with user modifications will no longer be able to:
Receive official product software updates.
Communicate with Q Experience cloud services.
Connect to the Q Experience mobile applications.
This limitation does not affect the user’s rights under the GPL and LGPL licenses: the user retains full ability to rebuild, modify, and run all open source software components on the device. However, access to proprietary Q Experience online services requires the official, unmodified software distribution with verified security credentials to ensure both system security and correct operation.
