Hi Jeremy,
My site is set to de_DE (http://greifswald-logopaedie.de/). I translated everything a few months ago.
What surprised me is that Jetpack is in German everywhere in the Backoffice, except in the Stats. And there the language for all users is defined by my personal settings in WP.com (the account I used to link Jetpack to WP.org). I did the test. Changing in Personal settings the "Interface language" to german has now changed the Stats to German. Again, the rest was already in German.
But I don't want my WP.com settings to affect everyone using the WP.org website.
Tell me if you need anymore info. Thanks for your response on this case.
