At this stage, we don't have cards printed in languages other than English in our database. Unfortunately, finding a comprehensive database of foreign language cards is proving quite difficult.
That said, the scanning app will recognise cards printed in languages other than English but it will recognise and add them as English versions.
We plan to have language support as soon as possible.
In the meantime, you might find the tagging feature helpful. For example, we tag our cards printed in other languages with #foreign and then #italian or #russian etc. for it's specific language. That way, once we update the database we can easily swap them over.
