Privacy Policy


Your use of the DTF Site is subject to this Privacy Policy and our Terms of Use. Please read this Privacy Policy carefully to understand how we treat information collected on this Site.


The Diesel Technology Forum (DTF) appreciates the trust and respects the privacy of everyone who uses our website, www.dieselforum.org ("website"), or our other digital communications assets including our blast email distribution or who may engage with us on social media channels that we maintain. This Privacy Statement ("Privacy Statement") explains how DTF collects, uses, stores, and protects the information that we collect from users of our website and our other digital assets and describes your rights and choices regarding the information that we collect.

DTF is a U.S. non-profit organization dedicated to raising awareness about the importance of diesel engines, fuel, and technology. Forum Members, both in the U.S. and internationally, are manufacturers, suppliers and affiliate organizations involved in engines, vehicles and equipment, diesel and renewable fuels and emissions-control systems. As a result, information that we collect on our website and through our other digital assets, including personal information, may be transferred to our U.S. offices to permit us to comply with our legal and contractual obligations, to provide information and services to prospective and current Members, and to perform related business activities.

In addition, we may work with third-party service providers in the U.S. and in other countries to support our business activities. Thus, personal information may be transferred to, stored on servers in, and accessed from the United States and from countries other than the country in which the information was initially collected. In all such instances, we use, transfer, and disclose personal information solely for the purposes described in this Privacy Statement.

If you have any questions or concerns about this Privacy Statement or about DTF's privacy and data security practices, please contact us at privacy@dieselforum.org or by mail to

Information Collection Not Covered by this Privacy Statement

This Privacy Statement does not apply to personal information that DTF collects and uses for employment-related purposes, whether through this website or through a website operated on our behalf by a third-party service provider.

This Privacy Statement does not apply to data that DTF collects when it provides services to its Members through the Member-use-only portion of the website ("Member Site"). When you access the Member Site, you are doing so in a business capacity as a representative of your company, and your interactions with the Member Site are governed by our relationship agreement with your company.

What DTF Means by "Personal Information"

For purposes of this Privacy Statement, "Personal Information" means any information from or about a person that either identifies that person directly or that makes that person identifiable when it is combined with other information from or about that person from any source. Personal Information stops being personal information when it has been aggregated, de-identified, or otherwise anonymized sufficiently that the individual is no longer identified or identifiable using reasonable efforts, resources, and technology.

"Sensitive Personal Information" is Personal Information that reveals racial or ethnic origin, political opinions, religious or philosophical beliefs, or trade union membership; genetic and biometric data if used for identification purposes; data about health, sex life, or sexual orientation; and data about criminal convictions or offenses.

Information that We Collect Automatically When You Visit Our Website


Our website automatically creates logs regarding user sessions that contain information about the features that you use, the actions that you take, and the information that you access. When your session ends, DTF only retains the information in a statistical and aggregated format (non-personal information) that we use for research purposes, assessing the effectiveness of our website, and improving user experience.



Cookies are small pieces of information transferred to your computer's hard drive through your web browser to enable our systems to recognize your preferences and settings. Cookies collect information such as the type of search engine used, the sections of the Website visited, and other website usage information. Most browsers automatically accept cookies, and you may manually disable them. For more information on disabling cookies, go to the "help" menu on your browser or to www.networkadvertising.org/choices/ or www.youronlinechoices.com. Our website may still be viewed if you choose to disable cookies, but your use and enjoyment of our website may be adversely affected.

We use session cookies for website use and function, and those cookies expire at the end of the session. We use persistent cookies only to identify existing DTF Members when they visit the Member Site, and these cookies expire after 14 days. DTF may retain information from the session and persistent cookies in a statistical and aggregated format (non-personal information) for research purposes, assessing the effectiveness of our website, and improving user experience.



Our website uses Google Analytics, a web analytics service provided by Google, Inc. ("Google"). Google uses cookies to help us analyze how visitors use our website.

Only in exceptional cases will the full IP address be transmitted to a Google server in the U.S. and truncated there. Google will use this information for evaluating your use of our website, compiling reports on Website activity, and providing us with other analytic services relating to our Website and Internet use. Google will not associate your IP address with any other data held by Google.

We collect and retain information from Google Analytics in a statistical and aggregated format (non-personal information) for research purposes, assessing the effectiveness of our website, and improving user experience.

Information that We Collect from Email Tracking Technology

The email service uses tracking technology to provide us with information about when our emails are delivered and opened, as well as actions that the recipients take, including clicking on links included in the email and forwarding the email to others. We receive that information for individual recipients and also in an aggregated format that is no longer Personal Information. Recipients of our emails can opt-out or unsubscribe at any time, by using the unsubscribe link in each email we send or by contacting us as shown below.
