These are cookies that are required to provide you with features or services that you have requested. For example, Cookies that enable you to log into secure areas of our site. Disabling these Cookies will encumber the Services’ performance and may make certain features and services unavailable.
These Cookies are used to recognize you when you return to our Services. This enables us to personalize our content for you, greet you by name, and remember your preferences.
These Cookies allow us to understand how visitors use our site. This includes information about the number of visitors to the site, what pages visitors view on our site and how long visitors are viewing pages on the site. Analytical Cookies also help us measure the performance of our advertising campaigns in order to help us improve our advertising campaigns and to optimize our Services’ content for those who engage with our advertising.
Third Party Cookies
These are Cookies placed by a third party on your device and may provide information to those third parties about browsing habits (including your visits to our Services, the pages you have visited and the links and advertisements you have clicked) that may help identify if certain services that such third parties provide are being used, identify your interests, retarget you and serve advertisements that are relevant to you. We do not have control or access to such third-party Cookies.
Session Cookies and Persistent Cookies
The types of Cookies described above may be “session Cookies” which are temporary Cookies that are only stored on your device while you are visiting our site or “persistent Cookies” which are Cookies that are stored on your device for a period of time after you leave our site. The length of time a persistent Cookie stays on your device varies from Cookie to Cookie. We use persistent Cookies to store your preferences so that they are available for the next visit, and to keep a more accurate account of how often you visit our Services, how often you return, how your use of the Services may vary over time and measure the effectiveness of advertising efforts. [GD3] Through these Cookies, we may collect information about your online activity after you leave our Services. Just like any other usage information we collect, this information allows us to improve the Services and customize your online experience. Your browser may offer you a “Do Not Track” option, which allows you to signal to operators of websites and web applications and services (including behavioral advertising services) that you do not wish such operators to track certain of your online activities over time and across different websites. Our Services do not support DO Not Track requests at this time, which means that we collect information about your online activity both while you are using the Services and after you leave the Services. Do Not Track signals are set on a browser-by-browser basis, so you must set them on every browser you use if you do not wish to be tracked.
Third Party Analytics Cookies
We use third party analytics services in order to better understand user engagement with the Services. When a user browses or uses the Services, these third-party analytics services may collect the user’s IP address, browser type, and approximate location (based on the IP address). They may also use web logs or web beacons and may set and access Cookies on your computer or other device. In order to refine our understanding of user engagement, we provide these services with a user’s name and email address (which we collected as part of the user’s account registration process).
You can decide whether or not to accept Cookies. One way you can do this is through your internet browser’s settings.
