 Web 服务只会请求上述服务端环境变量配置的模型地址，页面中地址为只读；这可防止浏览器借用本地 API 访问其他内网服务。macOS 客户端直接在本机发起模型请求，仍允许用户在设置中修改兼容 API 地址。

+API keys remain in application memory and are not written to browser storage or committed to the repository. With a cloud model or remote Ollama URL, selected text, manual input, and extracted document text are sent to the configured service; the default localhost Ollama URL and dictionary mode do not send that content to the cloud. Never include keys, selected text, or private documents in a public GitHub issue.
 
 ## Common blockers
 
-- The shortcut cannot read the selection: check Wordwise under **System Settings -> Privacy & Security -> Accessibility**, then restart the development app.
+- The shortcut does not respond: confirm that selection translation is enabled in Settings and that another app has not reserved the key combination.
+- The shortcut cannot read the selection: check Wordwise under **System Settings -> Privacy & Security -> Accessibility**. The copy fallback also needs Wordwise to control System Events under **Automation**. Restart the development app after changing either permission.
 - Automatic mode reports that no engine is configured: make sure Ollama is running and use `ollama list` to confirm that the model was downloaded.
 - A development port is already in use: stop the existing Wordwise development process and try again.
