A: Hey, sinhtruong!

We *did* just add frontend translation features, that translate key parts of the product for your recipients. Right now, we have a few languages... but it's easy to add more. You can just email support@breezedoc.com, and we'll send you the language files to help us translate. From there, it typically takes 1-2 weeks for the translation to be uploaded into the system and available for users to select in their settings.
