MacJanu is a program for keeping track of your computer's public Internet address and emailing it to you if it changes. MacJanu discovers your IP by querying a remote JanuServer and evaluating it to see if it has changed since MacJanu started. If your IP has changed then MacJanu will send you an email to your specified email account. No information is sent to or retained by the JanuServer.
