Language preferences can be set by the user, the instructor in a specific course, or the admin for the entire account. However, depending on the Canvas area, some language preferences can be overridden.
Language translations are either professionally translated and maintained by Instructure or translated through crowdsourcing. Crowdsourced translations may be incomplete and items that have not been translated will display in English (United States).
If no language is set, Canvas defaults to English (United States).
