It’s a pop up saying that they use a third party service to translate the website and they collect the activity of the user( which I don’t understand, why would they collect any user data to translate a static website). But it’s typical German like data protection and all the shenanigans.
Also the UI of the buttons on the popup is terrible both accept and reject buttons looks the same
You should be glad that the popup isn't using any dask patterns to coerce you into choosing an option you wouldn't otherwise agree with
