There are widgets with account performance, you can pick language, and some other settings but no language,
Here how I see it in Polish:
Gain: Zysk
Drawdown: Max. Spadek
Daily: Dziennie
Monthly: Miesięcznie
Updated: Aktualizacja
As you can see word for 'Updated' is quite long to fit some widget windows, you can instead use word 'Date'
Date: Data
EDIT:
There is a typo in topic, should be 'Translate'
