Privacy Policies

There are various facilities accessible to the users on the APEX's web pages. Some of these include forms where the user is requested to fill in some data or information on themselves (e.g. their e-mail address or name). In addition, our information services (www, ftp, mail/majordomo servers etc.) keep logs of certain information. APEX's privacy policy can be stated simply:
We will not collect any personal information about you when you access our network services unless you choose to provide that information to us.

Information which the APEX maintains about our user community, such as e-mail addresses of observers and of mailing-list subscribers, is normally available only for internal access. Please note, however, that the archives of some e-mail discussion groups hosted by APEX are, by request of the group involved, publicly accessible. By posting to these discussion groups, you may therefore make public the e-mail address from which you posted.
E-mail addresses and other information obtained through any of the means below will NOT be sold or released to any third party, without prior written or authenticated e-mail consent from the owner of the information.

Web access
If you do nothing during your visit but browse through the website, read pages, or download information, information about your visit will automatically be gathered and stored. This information does not identify you personally. We collect and store only the following information about your visit:

  1. The Internet domain (for example, "" if you use a private Internet access account, or "" if you connect from a university's domain) and IP address (an IP address is a number that is automatically assigned to your computer whenever you are surfing the Web) from which you access our website;
  2. The type of browser and operating system used to access our site;
  3. The date and time you access our site;
  4. The pages you visit;
  5. If you linked to the APEX's website from another website, the address of that website.

The information is private and confidential and will not be released to the general public. It is useful to help making our site more useful to visitors. E.g. to learn about the number of visitors to our site, the types of technology our visitors use, and what domains are our biggest users. We do not track or record information about individuals and their visits.
This site contains links to other sites. APEX is not responsible for the privacy practices or the content of these Web sites.

FTP access
The policy in the Web section above applies here. In addition, our ftp server records whether your access was in binary or ASCII mode, and whatever e-mail address you enter as a "password" for anonymous ftp access (your browser may decide this; e.g., under Netscape, Edit Preferences, Advanced section, there is an option called "send email address as anonymous FTP password").

Any incoming electronic mail to APEX will generate several log entries that include the routine information associated with normal SMTP (Simple Mail Transport Protocol) operation. Such log entries do NOT include the body (main text) of the message.
In all cases, the information on mail transactions is collected and retained in log files which will not be made available to the general public. The log entries will contain the e-mail address of the sender, its size, the number of recipients, the message ID, and the actual recipient within APEX and status of delivery (deferred, success, etc.)
This information is kept purely to help us diagnose system problems, or activities that may violate our Acceptable Use Policy or other Operation
