Jetpack localization


I have installed Jetpack plugin (which I believe you know about) and now I'd like to translate it. It has it's own language file, but it translates only some part of it.. Jetpack includes for example Wordpress.Com stats and default jatpack.po file doesn't let me to translate it, maybe services need their own language files?

I have tried to contact Jetpack(.me) support for this question and the site redirected me to which is closed for now.. So I've decided to ask you as you're WP Experts.
