How will Ducnguyen protect the privacy and anonymity of its users?


If you only want to learn about or discuss your own problems or those of your friends or relatives, you can choose to participate in Ducnguyen by pseudonym (keeping your real name secret). Other users must register using their real names.

If you choose to participate with your name, Ducnguyen will give you a password, which you can use so that other people cannot participate using your name. The password is transmitted in encrypted format to ensure your protection.

If you check "Do not show my e-mail address to other users" below, then the e-mail address which you specify will not be shown to other Ducnguyen users. Instead, they will be shown an e-mail address which refers to your account in Ducnguyen.

If you choose to participate by pseudonym, you will be asked to select a secret name, a pseudonym. If you keep this name secret, other users will not know who you are. You will have a password, so that other people cannot participate using your pseudonym.

We will do our utmost to preserve the secrecy of your pseudonym, but we may have to break this secrecy if you write illegal things (like racial agitation), and the police or a court require us to identify you.

If you misuse your account, we may cancel your access to Ducnguyen, but still without identifying who you are. If we have cancelled your account, but you continue to misuse Ducnguyen, then we may have to find out who you really are in order to stop the misuse.

Ducnguyen may be used for research on how people use the Internet to find information. The researchers will, however, never know the real name behind your secret name (pseudonym) without your explicit permission.
