Cookies are small data files that are placed on your computer or mobile device when you visit a website. Cookies are widely used by website owners in order to make their websites work, or to work more efficiently, as well as to provide reporting information. We use both “session ID cookies” and “persistent cookies.” Session ID cookies are used to store information while a user is logged in to the Services and expire when the user closes his/her browser. Persistent cookies are used to make tasks like logging in to the Services easier for returning users by remember a user’s login information. Persistent cookies stay on a user’s hard drive from one session to the next.
Cookies set by the website owner (in this case, NHM) are called “first-party cookies”. Cookies set by parties other than the website owner are called “third-party cookies”. Third-party cookies enable third-party features or functionality to be provided on or through the website (e.g., like advertising, interactive content and analytics). The parties that set these third-party cookies can recognize your computer both when it visits the website in question and also when it visits certain other websites.
We use first-party and third-party cookies for several reasons. Some cookies are required for technical reasons in order for our websites to operate, and we refer to these as “essential” or “strictly necessary” cookies. Other cookies also enable us to track and target the interests of our users to enhance the experience with NHM, to collect information for record-keeping purposes and to make it easier to navigate the Services. Third parties serve cookies through our websites for advertising, analytics and to deliver services such as membership functionality and webinars.
We also use other tracking technologies that perform like cookies as follows:
Web beacons (sometimes called “tracking pixels” or “clear gifs”) are also used to recognize or track visitors to a website. These are tiny graphics files that contain a unique identifier that enable us to recognize when someone has visited our websites or opened an e-mail that we have sent them. This allows us, for example, to count visitors, to monitor how users navigate the Services, to count how many emails that were sent were actually opened or to count how many particular articles or links were actually viewed. In many instances, these technologies are reliant on cookies to function properly, and so declining cookies will impair their functioning.
We use HTML5 in some of our applications, including in our mobile website for the iPhone or iPad. HTML5 has browser web storage that does not rely on traditional browser cookies. HTML5 cookies are not stored in a browser “cookies” file and can be used to track users across websites. To our knowledge there is currently no known way for a user of a mobile device to remove HTML5 tracking and storage.
E-tags/cache browsers/web logs
Like most standard website servers, we log IP addresses (a unique number assigned to every computer on the internet) and device identification in order to improve security, analyze trends and administer the Services. We may track your movement within the Services, the pages from which you were referred, access times and browser types. This information may include the browser you are using, the internet address from which you linked to our Services, the operating system of your computer, the unique IP address of the computer of device identification from the mobile device that you used to access our Services and usage and browsing habits. We use this information to gauge the effectiveness, usage, and popularity of our Services, track information for statistical purposes, help diagnose and troubleshoot server malfunctions, analyze trends, track user movement in the aggregate, and gather broad demographic information. We may also use individual information we collect through web logs to send you targeted offers and other communications.
To help you understand the types of cookies which are served through our websites, the entities that serve them and the purposes they perform, we have provided this table for you but please note that the specific cookies served may also vary depending on the web pages you visit.

Google Tag Manager
These cookies are used to make advertising messages more relevant to you. They perform functions like preventing the same ad from continuously reappearing, ensuring that ads are properly displayed for advertisers, and in some cases selecting advertisements that are based on your interests. We may use these to deliver content, including advertisements relevant to your interests on the Services and third party sites based on how you interact with our advertisements or content, as well as to track the content you access.
|Social networking cookies
These cookies are used to enable you to share pages and content that you find interesting on our websites through third party social networking and other websites. These cookies may also be used for advertising purposes too.
We may use Tracking Technologies to collect information about your use of the Services and other third-party websites in order to serve more targeted advertising to you. To serve our ads, we use a variety of third party advertising service providers, including networks, data exchanges, ad servers, analytics providers and others. These third parties may use Tracking Technologies to send directly to your device the advertisements and links that appear on the Services. They automatically receive your device identifier when this happens. Their tools may also limit the number of times you see the same advert and help measure the effectiveness of our advertising campaigns.
These third parties may also use information gathered from your use of the Services to serve targeted, interest based advertisements to you on third party websites and applications. Third parties may serve cookies or Tracking Technologies on your computer or mobile device to serve advertising through our websites. These companies may use information about your visits to this and other websites in order to provide relevant advertisements about goods and services that you may be interested in. They may also employ technology that is used to measure the effectiveness of advertisements. This can be accomplished by them using cookies or web beacons to collect information about your visits to this and other sites in order to provide relevant advertisements about goods and services of potential interest to you. The information collected through this process does not enable us or them to identify your name, contact details or other personally identifying details unless you choose to provide these.
Some of the advertising service providers may be members of the Network Advertising Initiative, which offers a single location to opt-out of ad targeting from member companies. If you opt out of receiving targeted ads in this manner, you will continue to receive advertising messages, but they will not be customized to you based on your use of the Services and third-party sites.
If you would like more information about advertisers’ use of tracking technologies and about your option not to accept them, you can go to www.networkadvertising.org. To learn more about how interest-based information is collected, whether the companies we use are part of an industry network regarding behavioral advertising, or to know your choices about not having information used in this manner, you can go to www.aboutads.info. Some newer mobile device operating systems allow you to limit the use of information to deliver interest-based advertising in mobile applications. You can check the settings on your mobile device for such options in your mobile devices’ operating system. Alternatively, you may wish to download the TrustE mobile application and/or the Digital Alliance “App Choices” mobile application and follow the instructions provided.
