Tracking Technologies

Cookies and similar technologies. Some of the automatic collection described above is facilitated by the following technologies:

• Cookies, which are small text files that websites store on user devices and that allow web servers to record users’ web browsing activities and remember their submissions, preferences, and login status as they navigate a site. Cookies used on our sites include both “session cookies” that are deleted when a session ends, “persistent cookies” that remain longer, “first party” cookies that we place and “third party” cookies that our third-party business partners and service providers place.  

• Local storage technologies, like HTML5, that provide cookie-equivalent functionality but can store larger amounts of data on your device outside of your browser in connection with specific applications. 

• Web beacons, also known as pixel tags or clear GIFs, which are used to demonstrate that a webpage or email was accessed or opened, or that certain content was viewed or clicked.

• Chat technologies, such as those provided by Intercom or other service providers to operate the chat features that you can use to communicate with us through the Service.  Intercom and other service providers may access and use information about webpages visited on our website, your IP address, your general geographic information (e.g., city, state), and other personal information you share through online chats for the purposes described in this Privacy Policy. 

For information concerning your choices with respect to the use of tracking technologies, see the Your choices section, below.
