Information We Collect Upon Registration
Visitors registering for services on our websites are asked to provide identifying information, such as name, contact information, and other identifying information. On the registration screen, we clearly label which information is required for registration, and which information is optional and may be given at your discretion. You will also be given a choice about whether or not you want to receive email information. diaDexus websites require visitors' consent before collecting personally identifiable information.

Information From Outside Sources
We may also collect information about physicians or other healthcare professionals who register on our websites from other sources in order to verify their licensure status and identity.

Use of Cookies and Other Tracking Systems
Cookies and log files are technologies used by diaDexus websites to identify users as they move through our websites. Your browser allows us to place some information on your computer's hard drive that identifies the computer you are using. We may use these or other technologies to personalize our websites and to track your usage across other websites.

Although cookies do not normally contain personally identifiable information, if you have provided us information about you, we may associate your registration information with cookies our website places on your computer's hard drive. Associating a cookie with your registration data allows us to offer increased personalization and functionality. Without cookies, this functionality would not be possible.

Your web browser can be set to allow you to control whether you will accept cookies, reject cookies, or to notify you each time a cookie is sent to you. If your browser is set to reject cookies, websites that are cookie enabled will not recognize you when you return to the website, and some website functionality may be lost. The help section of your browser will tell you how to prevent your browser from accepting cookies.

Aggregate Data
We create aggregate data about visitors to our websites for product development and improvement activities. We also use it for market analysis. We may provide information from our websites in aggregate form, with identifying information removed, to third parties. When aggregate health information is provided, we pool it from many individual records and remove any data that could be used to identify an individual before it is used. Any third party that receives aggregated healthcare data must agree not to attempt to re-identify the people it belongs to.

Marketing
We may target our marketing depending on information we have about you. We may send information to you that we believe may benefit you, including information about any diaDexus product.

We may also personalize our website based on your interests. For example, you may see different articles in different places on our website based on information you have shared with us, or information we have gained by reviewing your previous visits, or information we may have gained from your interactions with a third party that shares information with us.

When we share information with third parties, we use our best efforts to assure that they agree in writing to abide by diaDexus privacy policies. If we discover that a third party inappropriately disclosed personal information about any of our visitors, we will take action to prevent further occurrences. Other than as described above, diaDexus will not release personally identifiable information to a third party without your consent. Also, if we ask your consent to release personal healthcare information to a third party, we will use our best efforts to clearly define and limit the scope of your consent.

General Policies
We have implemented technology and security policies, rules and other measures to protect the personal data that we have under our control from unauthorized access, improper use, alteration, unlawful or accidental destruction, and accidental loss. We also protect your information by requiring that all our employees and others who have access to or are associated with the processing of your data, respect your confidentiality.

Third Parties
In addition to aggregate information (discussed previously), we may share some kinds of information with third parties as described below: Companies and people who work for us: Because we are a large company, we contract with other companies and individuals to help us provide services. In order to perform their jobs, these other companies may have limited access to some of the personal information we maintain about our users. We require all such companies to comply with the terms of our privacy policies, to limit their access to any personal information to the minimum necessary to perform their obligations, and not to use the information they may access for purposes other than fulfilling their responsibilities to us. We use our best efforts to limit the use of other companies in areas where personally identifiable healthcare information may be involved.

Legal Requirements
We may release account and other personal information when we believe release is required to comply with law. We may release personal health information, if, in our judgment after review by an attorney, the release is compelled by law or regulation, or if the release may be necessary to prevent the death or serious injury of an individual.
