I just opened a web page in Google Chrome, and it says "This page is in Japanese, would you like to translate it?".
Asking for a translation would presumably send the contents to Google, but how is the language identified in the first place? Is this done locally, in the browser? Or does this also send the page to Google? If so, should I not be asked for permission first? The page itself has no markup to indicate the language, and it is an internal intranet page, so that I am not at all sure that Google should be having access to its content.

The Chrome browser can identify, or at least guess, the page language by looking at a number of on page factors:
This can be done locally without any further internet connection or reporting to Google.
Translation of the content would definitely send the page content to Google servers for translation.
