Privacy statement

Introduction

MDU Resources recognizes the importance of protecting the privacy of all information provided by visitors to this Web Site. We created the following policy guidelines to guide our relationships with our users based on a fundamental respect for your right to privacy.

Collection and Security of Personal Information

MDU Resources collects some information voluntarily offered by users of this Web Site. MDU Resources uses reasonable precautions to maintain the security of the personal information of users and to disclose such information only to third parties after permission from the user. However, no security system is perfect. Therefore, MDU Resources is not responsible if someone manages to circumvent our security measurers and gain access to the database, including information pertaining to individual users, nor can we be responsible for any use, reproduction, or disclosure they may make of it.

Disclosure to Third Parties

MDU Resources may disclose specific user information (such as identity and contact information) if we believe that such disclosure is necessary or desirable to: (i) fulfill legal or regulatory requirements, (ii) protect our rights or those of others, (iii) prevent or mitigate harm or damage of any kind or nature, or (iv) address or seek redress for a violation of these Terms of Use or other obligations to MDU Resources or any third party, including our partners, advertisers, and other users.

Additionally, MDU Resources may collect, analyze, and disclose to others aggregated information (which includes users’ specific information but only as an unidentifiable part of the aggregate) gathered from overall use of the Web Site or particular features or areas of the Web Site. Among other purposes, this information allows us to analyze usage trends so that we can maintain an effective, responsive site.

Finally, if MDU Resources, or one of our lines of business, is sold, merged with, or otherwise acquired by a third party, your information may be (i) disclosed, under duty of confidentiality, to a potential purchaser or merger partner as part of the pre-closing due diligence process, or (ii) included among the transferred assets.

Contact by MDU Resources

Through the use of e-mail addresses provided at registration or otherwise, MDU Resources periodically sends out e-mail newsletters and promotional e-mail to our users about services and products offered by MDU Resources. Upon request, we will remove you (and your information) from our database or permit you to otherwise "opt-out" of any further e-mail newsletters or contact.

Partners, Linked Sites, and Advertisers

In addition to the information we collect, our partners or advertisers may collect information that you provide in connection with a co-branded page, such as partner-sponsored contest on the Web Site. In such cases, the information is the property of the sponsoring partner, as well as MDU Resources. Additionally, if you provide information to a web site that is linked to this Web Site, the information is the property of the linked site’s owner – and may be used as outlined in that site’s privacy policy, MDU Resources is not responsible for the content terms of use, privacy policies, or acts or omissions of web sites to which we may provide links or the web sites of our business partners or advertisers. We do not necessarily recommend or endorse the services or goods offered by any co-branding partner, advertiser, or linked site.

MDU Resources may revise the Terms of Use or Privacy Policy from time to time. Unless stated otherwise, changes will become effective immediately upon their posting.
