Like many web sites, we automatically gather certain information about our Site traffic and store it in log files.

We may use this information, which does not identify individual users, to analyze trends, to administer the Site, to track users’ movements around the Site and to gather demographic information about our user base.

This Privacy Policy places no restriction on the use of non-personal information we collect from your visit, or de-identified or aggregated information. We will not treat as confidential any information that you provide that is not personal, such as questions, comments, ideas or suggestions. You should be aware that we will be free to disclose through any means and use for any purpose such information in our sole discretion. By providing such information to us, you understand and agree that no relationship has been created between Merrimack and you, and Merrimack has no obligation to you whatsoever regarding that information.

Use of Cookies

Periodically, some pages on the Site may use “cookies,” which are small files that the Site places on your hard drive for identification purposes. These files are used for Site registration and customization the next time you visit us. We may use third parties to collect anonymous traffic data on our behalf. You should note that cookies cannot read data off of your hard drive. Your web browser may allow you to be notified when you are receiving a cookie, giving you the choice to accept it or not. You can also refuse all cookies by turning them off in your browser. By not accepting cookies, some pages may not fully function and you may not be able to access certain information on the Site.

Conditions Under Which We Share Information

We may share aggregated demographic information about our user base with third parties that may or may not be affiliated with us, but this information does not identify individual users. We do not link aggregate user data with personal information.

We share personal information with third parties that we rely upon to operate and administer the Site and to process requests and transactions made through the Site. We disclose information as needed for these service providers to perform their functions, but do not authorize the service providers to use the information for other purposes. You expressly consent to the sharing of your personal information with our service providers for such purposes.

We reserve the right to disclose your personal information as required by law, when we believe that disclosure is necessary to protect our rights; to protect the rights, property or safety of other persons; to comply with a judicial proceeding, court order or legal process served on us or the Site; or to a potential or actual acquiror who purchases Merrimack or the assets to which such information pertains. We may also disclose personal information in accordance with any notice provided to you at the time such information is collected, or as you otherwise authorize.

The Site is not intended for use by individuals who are not residents of the United States. Your personal information may be processed in the country in which it was collected and in other countries, including the United States, where laws regarding processing of personal information may be less stringent than the laws in your country.
