Why is the website in German?

I'm in the United State, but when I go to the website all text is in German and Chrome asks if I want to translate the webpage. Why is it doing this and how do I fix it?

We would like to apologize for the inconvenience caused.

The issue is supposed to be fixed. However, you may need to clear JotForm website cookies in your browser, and then log in again.
