You may modify or remove your Personal Information or Children's Personal Information identified below at any time by logging into your account and accessing features to edit your profile and/or account information or by emailing us at

2. Information collected automatically:

Company automatically receives and records information on our server logs from your browser including your IP address, Company cookie information, and the page you requested, pages you view before and after visiting the Website (including search queries you may have entered to find the Website), and other similar information. We also record the details of your activity on the Website.

Generally, our service automatically collects usage information, such as the numbers and frequency of visitors to our site and its components, similar to TV ratings that indicate how many people watched a particular show. Generally, Company uses this data in aggregate form, that is, as a statistical measure, and not in a manner that would identify you personally, although in certain situations, such as performing customer support, individually identifiable log data may be used to provide you with better service. This type of aggregate data enables us to determine how often users use parts of the Website or services so that we can make the Website appealing to as many users as possible, improve those services, and improve our ability to support our users. As part of this use of information, we may provide aggregate, non-personally identifiable information to our partners about how our users, collectively, use our site.

If you provide us your email address and/or cell phone number, we may send you email or sms communications. If you are a student, we will only use your email address to send you Notifications. If you are not a student, we may receive a confirmation when you open an email from Company if your computer supports this type of program.

We strongly recommend that you leave the cookies activated, however, because you will not be able to log in or use many of the Website's most attractive features without cookies enabled.
