We automatically track certain information about you based upon your behavior on our Site. We use this information to do internal research on our users' demographics, interests, and behavior to better understand and serve you and our community.

You may encounter "cookies" or other similar devices on certain pages of our Site that are placed by third parties. For example, if you view a web page created by a user, there may be a "cookie" placed within that web page. We do not control the use of cookies by third parties.
If you send us personal correspondence, such as emails or letters, or if other users or third parties send us correspondence about your activities or postings on the Site, we may collect such information into a file specific to you.

3. Our Use of Your Information
You agree that we use personal information about you (including but not limited to the information in the file we maintain about you, and other information we obtain from your current and past activities on the Site) to resolve disputes, troubleshoot problems, help ensure safe trading. At times, we may look across multiple users to identify problems or resolve disputes, and in particular we may examine your information to identify users.
To protect the www.corebuilding.com.cn from frauds, illegal activities and other crimes on the Internet, you agree that we may evaluate your personal information through manual or automated procedures. Consequently, evaluation code may be added to the files held by us.
You agree that we may use personal information about you to improve our marketing and promotional efforts, to analyze site usage, to improve our content and product offerings and customize our Site's content, layout, and services. These uses improve our Site and better tailor it to meet your needs, so as to provide you with a smooth, efficient, safer and customized experience while using our services.
You agree that we may use your information to contact you and deliver information to you that, in some cases, is targeted to your interests, such as targeted banners, administrative notices, product offerings, and communications relevant to your use of the Site. By accepting the Privacy Policy you expressly agree to receive this information.

4. Our Disclosure of Your Information
Although Core Building uses industry standard practices to protect your personal information, due to technical limitations, we cannot ensure that all of your private communications and other personal information will never be disclosed in ways not otherwise described in this Privacy Policy. By way of example (without limiting the foregoing), we may be forced to disclose information to the government or third parties under certain circumstances (further details of which are set out below in the "Legal Requests" section), or third parties may unlawfully intercept or access transmissions or private communications. Therefore, although we use industry standard practices to protect your privacy, we cannot and do not guarantee, and you should not expect, that your personal information or private communications will always remain private.
As a matter of policy, we do not sell or rent any personal information about you to any third party. However, the following describes some of the ways that your personal information may be disclosed, and by agreeing to the Privacy Policy you expressly agree that your personal information may be disclosed by Core Building in the following ways:

5. Advertisers.
We aggregate (gather up data across all user accounts) personal information and disclose such information in a non-personally identifiable manner to advertisers and other third parties for marketing and promotional purposes. However, in these situations, we do not disclose to these entities any information that could be used to identify you personally. Certain information, such as your name, email address, password, credit card number, and bank account number, are never disclosed to advertisers.

6. External Service Providers.
There are a number of services offered by external service providers that help you use our Site (e.g., co-branded sites, listing agents, authentication, mediation). If you choose to use these optional services, disclose personal information to the external service providers, and/or grant them permission to collect personal information about you, then their use of your personal information is governed by their privacy policy. We will not disclose your personal information to external service providers without your express consent. However, we may, for your convenience, provide some of your personal information to the external service provider offering such services with your express consent. To prevent our disclosure of your personal information to an external service provider, you can decline such disclosures or simply not use their services. Because we do not control the privacy practices of these third parties, you should evaluate their practices before deciding to use their services.

7. Internal Service Providers.
We may use internal service providers to facilitate our services (e.g., search, discussion boards, surveys) and therefore we may provide some of your personal information directly to them. In some instances, the internal service provider may collect information directly from you (such as the situation where we ask a internal service provider to conduct a survey for us).

8. Legal Requests.
Core Building may lawfully disclose your personal information for law enforcement or regulatory purposes. Core Building cooperates with law enforcement inquires and other third parties to enforce laws and other rights. We can (and you authorize us to) disclose any information about you to law enforcement or other governmental officials as we, in our sole discretion, believe necessary, appropriate or as otherwise permitted under applicable Chinese or international laws, in connection with an investigation of fraud or other activity that is illegal or may expose us to legal liability.

9. Other Information Collectors
Except as otherwise expressly discussed in this Privacy Policy, this document only addresses the use and disclosure of information we collect from you. To the extent that you disclose your information to other parties, whether they are users of our Site or other sites throughout the Internet, different rules may apply to their use or disclosure of the personal information you disclose to them. To the extent that we use third party advertisers, they adhere to their own privacy customs and policies. Since Core Building does not control the privacy policies of third parties, you are subject to the privacy policies of that third party. We encourage you to ask questions before you disclose your personal information to others.

10. Security
Your Information is stored on Core Building's server. We use industry standard efforts to safeguard the confidentiality of your personal information. However, "perfect security" does not exist on the Internet. As stated elsewhere in this Privacy Policy, the content on Internet and the content provided by third parties may cause damage to your system. We strongly encourage you to protect your system with such means as anti-virus software and firewall.

11. Notice
We may change this Privacy Policy from time to time based on your comments and our need to accurately reflect our data collection and disclosure practices. All changes to this policy are effective after we provide you with at least thirty (30) days' notice of the changes
