What information does CBO collect and store automatically?

As you browse through our Web site, we automatically gather and store certain information about your visit. That information includes the Internet domain and IP address from which you accessed our site; the date and time of your visit; the type of browser and operating system you used; the pages you visited and the files you downloaded; and, if you linked to the CBO site from another website, the address of that site.

We use that information to help us make our site more useful to you, our visitors—to learn about the number of visitors to our site, what information we provide is of most interest, and the devices and browsers you use to access the site.

We also collect information to help keep our site secure and to ensure that this site remains available to all visitors. We use software programs to monitor network traffic and identify unauthorized attempts to upload or change information or otherwise cause damage. Such unauthorized activities are strictly prohibited and may be punishable under law.

Except for the purposes already noted, no other attempts are made to identify individual users or their usage habits.

How we use your personal information

CBO does not automatically collect and store personal information other than that described in the previous section. Some users do submit personal information voluntarily.

E-mail. If you contact CBO by email, we will use any personal information you provide to respond to your message and to help us ensure that you receive any information you have requested.

CBO e-mail notifications. Users may sign up to receive e-mail notifications about CBO publications. Any information you provide as part of that sign-up process is used only to notify you of documents in requested areas of interest, errata information issued in connection with those documents, or general website information such as planned downtime for maintenance.

Any information you provide to us electronically is not shared with any other organizations, nor is it used for any commercial marketing purposes. We will, however, honor appropriate legal process seeking such information.
