Yes, the plugin should work for any language. There are no Hebrew translation files, but the main translation file is in place and up to date, so you could easily use PoEdit to create your own translation files.
My plugin is also compatible with WPML, and I have tested it with different languages on a test multilingual development site.
In addition, you are able to enter all the text & messages that appear to the public from the plugin settings, so you can replace the English defaults with Hebrew language text of your choosing.
