I just installed #amethyst and it's auto translating everything. It's annoying, I hope I'll fond how to disable it

You can either add a keyboard to the OS for the languages you speak (which is the right way of using multiple languages on Android) or when a translated text appears, you have a message at the bottom of the text where you can click and disable that language especifically.
Oh Vitor, many thanks, now I can disable english translations but keep japanese ones, that's really great!
