So I live in a country where the German language is prevalent. Personally I'm bilingual, I speak German as well, but I prefer English, because it's making one more compatible with the rest of the world. I guess it's like English being TCP / IP and German being some proprietary protocol that only a handful of obscure devices understand.
When I logged in to this website today, based on my IP address, the backend assumed that I wanted to read all texts in German, which I didn't.
What I dislike most about is that the backend uses information about me (my IP address) to make assumptions. I consider this quite rude, please change that.
