The installer asks for the language before the keyboard, and Setup > Language (omarchy language en|zh) switches it later. Under zh_CN the menu reads its labels from omarchy-menu.zh-cn.jsonc, the shell from I18nZh.js through I18n.tr, and notifications are worded by their sender through omarchy-text, which reads the same table. User text is never translated.
