Privacy Policy

Sigma and its subsidiaries value the relationship we have with our members, customers, and visitors.

We have created this privacy statement in order to demonstrate our respect for your privacy. The following discloses our information gathering and dissemination practices on the honor society's family of websites.

We suggest that you practice reasonable discretion with any site when providing personal information. Note also that whenever you post personal information in publicly accessible places, such as chat rooms or message boards, this information becomes available to anyone with access to the internet. Therefore, we recommend that you refrain from posting any information you do not want seen on public areas of the websites. Feel free to contact us if you have any questions regarding our policies.

What information is collected on Sigma Marketplace?

At different times, we may request the following information from our members, customers, or visitors. HOWEVER, BE INFORMED THAT WE DO NOT COLLECT OR STORE CREDIT CARD ACCOUNT NUMBERS.

Cookies: A cookie is assigned by your browser to identify your computer. The unique user ID contained within your cookie automatically identifies your computer—but not you—to our servers every time you visit our site. This allows us to "remember" information about your preferences and passwords and allows you to move within our website without reintroducing yourself. Cookies also allow our third-party web analytics service to measure the number of page views on our site. Cookies by themselves cannot be used to find out the identity of any user, but may be correlated with identity information in our log files. The help portion of the toolbar on most browsers will tell you how to prevent your browser from accepting new cookies, how to have the browser notify you when you receive a new cookie, or how to disable cookies altogether. However, turning off the cookies feature using your browser's preference options may limit your ability to utilize many of our site features.

IP Address: Your IP address (the address the Internet uses to identify your computer) is tracked to help diagnose problems with our server and to administer our website. Your IP address is also used to gather broad demographic information about you, such as your location and your internet service provider. Sigma Marketplace may also collect aggregate information on how our users are utilizing the site. This might include information regarding traffic patterns through the site and search queries.

Browsers: Browser types, access times, and URLs from which visitors came to our site and URLs viewed by visitors while on our site are logged. Except as otherwise stated in this privacy policy, we do not provide this information to third parties, except in aggregate form.

Personal Information: You may be asked to provide personal information in order for you to register for a service. This information may include but is not limited to your name and email address. You may always choose not to provide us with this information; however, this may limit our ability to provide you with a specific service or to deliver personalized content.

Credit Card Information: If you choose to register for any paid service or make purchases on our site, you will be requested to provide credit card information. Although we cannot guarantee complete security, we will use commercially reasonable efforts to protect all e-commerce transactions through the use of encryption.

Thawte Secure Server Certificate and Authorize.net Payment Solutions: In order to complete a transaction, payment information may be transferred through one of our partners who processes such information.

What organization is collecting the information?

Sigma and/or its subsidiaries, including Sigma Marketplace, may request the information. However, it may be shared with select partners to deliver additional services you have requested. The areas of our sites in which partners are collecting information may be co-branded with our partners' logos.


Some of our advertisers who display ads on our site, may use cookies. We do not control their use of cookies or have access to the information contained in or related to those cookies. Therefore, if you leave our site through a hyperlink, please be advised that we are no longer in control of the content you are exposed to.

What does Sigma do with the data it collects?

Whenever data is collected it is intended to tailor or improve the experience of visitors to our family of websites. From the data collected we can customize content and advertising based on the user's preferences. We analyze what our users prefer in order to improve our services and product offerings.

We use information from a cookie (a feature of your browser used to assign identification to your computer) to count and track site visits in the aggregate, to personalize the site for each unique user, to control the frequency of individual advertisements directed to individual computers, and to target advertisements to broad demographic segments. We may also use information about your interests to display product information or specific content that we have determined may be of interest. Some broad statistical customer data is provided to our advertisers (e.g., percentage of males or females visiting the site), but specific personal information is not shared with our advertisers, except as otherwise stated in this privacy policy.

We use IP addresses to help diagnose problems with our server and to administer our websites. IP addresses may be disclosed to a third party if we believe in good faith that the law or legal process requires it, or to protect the rights or property of Sigma and its subsidiaries or others.

When you register for unique services on our sites, such as to create an email account, we collect additional information from you in order to provide you with those specific services and to personalize your experience on the site. We may use such information to target our offerings or offerings of third parties that may be of interest to you and/or to analyze aggregate user data in order to improve our services.

On occasion we may email bulletins to provide you with information that we think you will find useful, including information about new products and services. We might also contact you to see if you are interested in participating in market research or to respond to customer-service questions submitted or to verify your account information if you submit a password request.

With whom does Sigma and its subsidaries share data?

With your permission, we may disclose your personal information to our business partners in order to provide you with the services you have requested. We do not have control over and are not responsible for the data collection and use practices of our business partners.

We also may disclose your personal information to a third party if we believe in good faith that the law or legal process requires it, to protect the rights or property of Sigma and its subsidiaries or as otherwise described in this privacy policy.

We also may share aggregate demographic information with our advertisers.

What choices are available regarding collection, use and distribution of the information?

As previously noted, you may always choose to not provide us with any of the information we request; however, this may limit our ability to provide you with a specific service or limit our ability to offer personalized content. For example, our email registration form requests your contact information and demographic information (such as your age and gender) as well as information regarding your interests.

How can you update or correct your information?

Users of our websites can review and modify their account or profile information on the site or alternatively by sending an email to us at customerservice@nursingknowledge.org

How can you delete your information or deactivate your registration?

You may deactivate your registration at any time.

Sigma Marketplace currently does not have a method for completely deleting user information from our database. However, deleting the cookie stored on your computer will cause you to be perceived as a new user with no known user data. You may also change a setting in your browser, instructing it not to accept cookies, but this could prevent you from receiving some Sigma Marketplace or Sigma services.

As a part of ongoing site maintenance, some information may automatically be deleted from our site after a certain period of time.

What procedures have been designed to protect the loss, misuse, or alteration of information under Sigma and its subsidiaries’ control?

Except as otherwise stated in this privacy policy, we have taken measures intended to restrict access to information that is not publicly available through its sites, to the user who initially entered the information, or to authorized personnel at Sigma Marketplace or its partners, and only after a password has been entered.

What about registration for Continuing Education Courses?

Sigma Marketplace hosts continuing education courses for our registered users online. Enrollment for such courses is completely optional and at your discretion. When you register for continuing education courses, you will be required to provide billing information exactly as it appears on your credit card statement so that we can process your order including your name, address, telephone number, credit card number, and expiration date. The information you provide is used solely for the purpose of consummating your purchase, and your credit card information will not be stored. We may record information about registration for continuing education courses to determine which courses appeal most to members of our group. This statistical information may help us to improve our product offerings.

Special contests and promotions
