Cronometer (GPL) goes web based, loses GPL ?

[linux guy]

I am a long time user of Cron-o-meter.  Its a Java GLP application for
nutritional monitoring.  It works great.

As long as I've know it (4 years), cronometer has been a GPL
application that you installed on your local computer.  As a matter of
fact, cronometer has and still does maintain a sourceforge account.
http://sourceforge.net/projects/cronometer/

However, Cronometer is now available as an online application.  The
provider has set up a web site that serves the application to users
via browsers connected to the internet

The online version of Cronometer has extra functionality, not included
in the local version.

"The original version of CRON-O-Meter is still available for download.
However, we highly recommend using the web version instead as it has
more features, a bigger database, and you can access your data from
anywhere. For those that prefer the stand-alone version, you can
download it below."   http://cronometer.com/download/

Even more functionality is available for the online version via a
premium membership.

No source code has been made available for the web served application.

Has the cronometer provided broken the rules of the GPL by enhancing
it and turning it into a web application and not providing the course
code back to the user base ?

If so, where and how should this be reported ?

Thanks !
