Checkout translation (not auto translating)

[bolfeed]

Hi there,

I'm facing an issue for a long time right now. My default language in Shopify is in local language and I would like to keep that. But I cannot find how to change my checkout language to another language than my main language (or I cannot find it). The perfect case would be that the language is auto-translated to the language of the customer (based on browser language or IP location). Is that possible? Or is there any other possibility to solve this issue?

Sidenote: I'm using transcy app to auto translate my store (but it's not translating the checkout section)

Thank you in advance!
