You are responsible for verifying procedures, specifications, safety requirements, and code compliance before relying on any information from this site in the field.
This site and its content are provided on an "as is" and "as available" basis without warranties of any kind, whether express or implied, including any implied warranties of accuracy, merchantability, fitness for a particular purpose, or non-infringement. We do not guarantee that the site will always be available, error-free, current, or suitable for your specific use.
You agree to use this site responsibly and only for lawful purposes. You must not misuse the site, interfere with its operation, attempt unauthorized access, introduce malicious code, or use the content in a way that could create unsafe, misleading, or unlawful outcomes.
Any installation, testing, termination, splicing, construction, or troubleshooting decisions you make remain your responsibility.

Unless otherwise stated, the site design, text, layout, graphics, and original compiled reference content on Color Optics are owned by the site operator and protected by applicable intellectual property laws. You may use the site for personal or internal reference purposes, but you may not copy, resell, publish, or redistribute substantial portions of the site without permission, except as allowed by law.
Any mention of cable categories, connector types, standards, trade names, or manufacturer-style references is for identification and informational purposes only and does not imply sponsorship, endorsement, or affiliation.
To the fullest extent permitted by applicable law, the site operator will not be liable for any direct, indirect, incidental, consequential, special, exemplary, or punitive damages arising from or related to your use of, or inability to use, this site or any reliance placed on its content.

This Privacy Policy explains how Color Optics handles information when you use this website and web app. Because this site is primarily an informational field-reference tool, the amount of personal information collected may be limited, but this policy is intended to explain what may be stored, how it may be used, and the choices available to users.
We may collect limited information in a few different ways: information you choose to provide directly, basic technical information automatically made available by your browser or device, and local preference data stored on your device to improve how the site works.
Color Optics stores certain settings locally in your browser, such as your last selected page, cable options, and reference selections, so the site can restore your previous state when you return. This information is typically stored on your device and is used to improve usability rather than to identify you personally.
Like most websites, the site may receive limited technical data such as browser type, device type, operating system, approximate usage timing, referring pages, and basic diagnostic or performance data. This type of information is generally used for site operation, maintenance, security, and improvement.
Information collected through the site may be used to operate the site, remember your preferences, improve performance, maintain security, troubleshoot issues, respond to messages you send, and understand how the site is being used so it can be improved over time.
The site may use browser storage, cookies, or similar technologies to support core functionality and remember settings. If analytics or third-party services are added later, this policy should be updated to describe those tools more specifically. You can usually manage cookies and local storage through your browser settings.
We do not sell personal information through this site as part of its normal operation. Information may be shared only as reasonably necessary to operate, secure, or maintain the site, to comply with legal obligations, to protect rights or safety, or in connection with a business transfer or restructuring if that ever becomes relevant.
Local browser-stored preferences may remain on your device until you clear them. Any information received through direct communications or future account features may be retained only as long as reasonably necessary for the purpose it was collected, unless a longer period is required by law or legitimate operational need.
Reasonable steps may be taken to protect information associated with the site, but no website, browser storage method, or internet transmission can be guaranteed to be completely secure. You use the site at your own risk and should avoid submitting sensitive information unless the site clearly requests it through an appropriate secure feature.
This site is not intended for children under 13, and we do not knowingly collect personal information from children under 13 through ordinary site use. If you believe a child has provided personal information, contact the site operator so the issue can be reviewed.
You can limit some data collection by adjusting your browser settings, clearing cookies or local storage, or choosing not to submit information through optional features. Depending on how the site develops, you may also have rights under applicable privacy laws regarding access, deletion, or correction of personal information.
This Privacy Policy may be updated from time to time. Any changes become effective when the updated policy is posted on this page. Continued use of the site after updates are posted means you accept the revised policy.
If you want users to be able to contact you about privacy questions, this section can be updated with a business name, mailing address, or public email address once you decide what contact details to publish.
