Group chat records are server-side; local task files and conversations are not the same data category. See the privacy policy for details. - Android device operation requires KK Phone Assistant and permissions. iPhone web remote access is not general control of iOS apps. - Users decide permissions for consequential actions. Available tools depend on the host, account, connectors and granted permissions; a task request does not guarantee successful execution. - Client downloads are free. Model usage and paid tools are billed separately by usage; consult account pricing and action confirmations. Free download does not mean free model usage. - 关键操作的权限由用户决定;模型调用及付费工具按用量另行计费。具体能力取决于宿主、连接器与授权。 ## Source guidance This file is a reading guide, not a service commitment.
