Cookies and Other Tracking Technologies

“Cookies” are small data files that are sent to your web browser when you access a website, and the files stored on your device’s hard drive. We use “session” cookies to keep you logged in while you use the Site, to track your preferences and to track trends and monitor usage and web traffic information on the Site. These are erased when you close your browser. We use “persistent” cookies to relate your use of our Service to other information about you and store information about your preferences to make your user experience consistent and customized. For example, we may create a persistent cookie that includes some basic information about you, like your favorite website locations and whether customer support responded to your inquiry. These cookies stay on your hard drive until you erase them or they expire and associate your information with your account even if you are logged out.

Most browsers automatically accept cookies, but you can change your settings on the browser settings to refuse cookies or prompt you before accepting cookies. You can also use your browser settings or other tools to delete cookies you already have. However, if you disable or refuse cookies, then certain features of the Site may be inaccessible or not function properly.

Our cookies do not, by themselves, contain Personal Information, and we do not combine the general information collected through cookies with other Personal Information to tell us who you are. As noted, however, we do use cookies to identify that your web browser has accessed aspects of the Service and may associate that information with your account if you have one.

Certain features of the Site may use local shared objects (or “flash cookies”). Flash cookies are small files similar to browser cookies that collect and store information about your preferences and where you browse and what you look at on the Site. Flash cookies are not managed by the same browser or device settings that are used for browser cookies. You may adjust your Adobe Flash Player settings to prevent flash cookies from being placed on your hard drive.

This Privacy Policy covers our use of cookies only and does not cover the use of cookies by third parties. We do not control when or how third parties place cookies on your computer. For example, third party websites to which a link points may set cookies on your computer.

We may use “clear GIFs” (aka “web beacons” or “pixel tags”) or similar technologies, on our Service or in our communications with you to enable us to know whether you have visited a part of our Service or received a message. A clear GIF is typically a one-pixel, transparent image (although it can be a visible image as well), located on a website or in an email or other type of message, which is retrieved from a remote website on the Internet enabling the verification of an individual’s viewing or receipt of a website or message.

We do not automatically collect Personal Information, but we may tie Personal Information with the automatically collected information using the above tools or information collected from other sources.
We may also log information using digital images called web beacons on our Site or in our emails. We may use web beacons to manage cookies, count visits, and to learn what marketing works and what does not. We may also use web beacons to tell if you open or act on our emails.

Third party analytic services are used to track general location information, and events that occur without our Site, such as how often you use our Site. This information, including your IP address, is transmitted and stored by 3rd parties as determined by us.
IP Address Information and Other Information Collected Automatically

We automatically receive and record log file information from your web browser when you interact with the Site, including your IP address and cookie information. Generally, the Site automatically collects usage information, such as the number and frequency of visitors to the Site. We may use this data in aggregate form, that is, as a statistical measure, but not in a manner that would identify you personally.
