ChromaChecker Corporation
Effective Date: August 5, 2026 Last Updated: August 5, 2026
IMPORTANT - PLEASE READ CAREFULLY
THIS END-USER LICENSE AGREEMENT ("EULA") IS A LEGAL AGREEMENT BETWEEN YOU (EITHER AN INDIVIDUAL OR A LEGAL ENTITY) AND CHROMACHECKER CORPORATION ("CHROMACHECKER," "WE," "US," OR "OUR") CONCERNING CHROMACHECKER'S SOFTWARE APPLICATIONS FOR DESKTOP AND MOBILE DEVICES ("SOFTWARE").
BY INSTALLING, COPYING, OR OTHERWISE USING THE SOFTWARE, YOU AGREE TO BE BOUND BY THE TERMS OF THIS EULA. IF YOU DO NOT AGREE TO THESE TERMS, DO NOT INSTALL OR USE THE SOFTWARE.
If you are accepting this EULA on behalf of a company or other legal entity, you represent that you have the authority to bind such entity to these terms.
1. Definitions

|---|---|
| Software | ChromaChecker desktop and mobile applications, including CC Capture, CC Curve, Datalogger, and other ChromaChecker client applications |
| Services | The ChromaChecker cloud platform and online services accessed via the Software |
| Subscription | Your active ChromaChecker service subscription |
| User | The individual or entity licensed to use the Software |
| Documentation | User guides, technical specifications, and help materials provided by ChromaChecker |
| Plugin | An optional software extension to the Software that adds functionality beyond the base application, distributed by ChromaChecker or by a third party |

| Organisation | The company or other legal entity identified in your ChromaChecker Subscription |
2. License Grant
2.1 Limited License
Subject to your compliance with this EULA and maintenance of an active Subscription, ChromaChecker grants you a limited, non-exclusive, non-transferable, revocable license to:
- Install and use the Software on devices you own or control
- Use the Software solely to access ChromaChecker Services
- Make reasonable backup copies for archival purposes
2.2 Scope of License
This license permits:
- Installation on multiple devices associated with your Subscription
- Use by authorized users within your organization (per your Subscription terms)
- Updates and new versions provided during your Subscription period
2.3 Subscription Requirement
The Software requires an active ChromaChecker Subscription to function. Without a valid Subscription:
- Core functionality will be disabled
- Data synchronization will cease
- You must uninstall the Software or renew your Subscription
2.4 Plugins and Extensions
The Software supports optional Plugins. Plugins are not covered by the license granted in Section 2.1 and are licensed separately.
(a) Separate licence. Unless stated otherwise for an individual Plugin, a Plugin licence is granted to the Organisation, not to an individual User, and is assigned to a specific computer (a "seat"). Any User authorised by that Organisation may use the Plugin on that computer. Reassignment of a seat to another computer is permitted under the conditions ChromaChecker publishes; repeated reassignment intended to share a single Plugin licence across multiple computers is not permitted and may result in the seat being suspended.
(b) Plugin Terms. Installing or using a Plugin requires acceptance of that Plugin's Plugin Terms, where published. In the event of conflict, the Plugin Terms prevail for matters specific to that Plugin, and this EULA governs all other matters. Plugin Terms may be updated independently of this EULA; a change to one Plugin's Plugin Terms does not modify this EULA or the terms of any other Plugin. Plugin Terms apply only to Plugins you install or use.
(c) Evaluation and change. Plugins may be made available for evaluation for a limited period. Plugin functionality is under active development: ChromaChecker may modify, replace or withdraw any Plugin, and functionality available during an evaluation period may afterwards be unavailable or require a paid licence.
3. License Restrictions
You shall NOT:
(a) Redistribute - License, sell, rent, lease, transfer, assign, or distribute the Software to any third party
(b) Reverse Engineer - Reverse engineer, decompile, disassemble, or attempt to derive the source code of the Software, except (i) as expressly permitted by applicable law, or (ii) with respect to third-party open-source components included in the Software (such as PySide6, Qt, and other LGPL-licensed libraries) to the extent required by their respective licenses. See the THIRD_PARTY_NOTICES.txt file distributed with the Software for details
(c) Modify - Adapt, modify, alter, translate, or create derivative works based on the Software
(d) Remove Notices - Remove, alter, or obscure any copyright, trademark, or other proprietary notices in the Software
(e) Circumvent - Circumvent or attempt to circumvent any license validation, access controls, or security measures
(f) Misuse - Use the Software for any unlawful purpose or in violation of any applicable laws or regulations
(g) Compete - Use the Software to develop a competing product or service
(h) Benchmark - Publish performance benchmarks without ChromaChecker's prior written consent
4. Intellectual Property

ChromaChecker™, CC Capture™, and associated logos are trademarks of ChromaChecker Corporation. This EULA does not grant any rights to use ChromaChecker trademarks except as necessary to identify the Software.

5.5 Consent
To the extent required by applicable law, by using the Software, you consent to data collection and processing as described in our Privacy Policy. If you do not consent where consent is required, you must stop using the Software.
6. Updates and Modifications

The Software may automatically download and install updates. These updates may include:

7. Technical Requirements
7.1 System Requirements
Before installing the Software, review the technical requirements published at: https://chromachecker.com/support/system-requirements
7.2 Internet Connection
The Software requires an active internet connection to:
- Authenticate your Subscription
- Synchronize data with ChromaChecker Services
- Receive updates
7.3 Third-Party Open-Source Components
The Software includes third-party open-source components, including PySide6 and Qt (licensed under the GNU Lesser General Public License version 3). These components are subject to their own license terms, which take precedence over this EULA with respect to those components. In particular, you retain the right to modify and replace the LGPL-licensed libraries as described in the LGPL v3. Complete license texts and source code availability information are provided in the THIRD_PARTY_NOTICES.txt, LGPL-3.0.txt, and GPL-3.0.txt files distributed with the Software, and in the "About" section of the application.
7.4 Third-Party Services Accessed Through Plugins
Certain Plugins connect to services operated by third parties. Where a Plugin uses your own account with such a provider, your use of that service is governed by the agreement between you and that provider; ChromaChecker is not a party to that agreement and does not control the provider's availability, security, pricing or data handling. You are responsible for holding the rights necessary to grant the Plugin access to that account and for the content you transfer through it.
7.5 Network Behaviour and Security Disclosure for Plugins
A Plugin may change the network behaviour of the computer it runs on — for example by opening a listening port, communicating on the local network, discovering or controlling devices, storing credentials or browser cookies, or starting a background process. Where a Plugin does any of these, its Plugin Terms and accompanying documentation state:
- which inbound ports it opens, on which interfaces, and how access to them is authenticated;
- which outbound destinations and ports it contacts;
- what data leaves your computer, and where it is stored;
- which credentials it stores, and where;
- any background process or service it starts.
You are responsible for deciding whether that behaviour is acceptable on your network and for configuring your firewall accordingly. ChromaChecker publishes a consolidated summary of this information for the Software and its Plugins so that it can be reviewed by your IT administrators before deployment.
