雨果巴拉还说明了MIUI云端信息处理电话号码的将关机制：
1，接收者的闭自电话号码只用于查找在线状态以及传递信息。
2，小米信息这使得发送者能立刻确定是私自上传否能发送免费的信息。我们相信保护用户数据与隐私是用户最优先的。没有联系人或社交图谱的信息会被储存于云端，并查找该联系人的在线状态(或者是否是云端短信的用户)。同时用户也可在那里关闭小米云端短信。以加密形式的(小米云端)短信也不会储存超出必要的用于传递信息的时间。雨果向MIUI用户与粉丝对此感到的担忧表示了歉意，并且不再会自动启用。
据cnbeta网站消息，新用户或进行了工厂重置了设备的用户可以从主界面进入“Settings > Mi Cloud > Cloud Messaging”或从短信应用的“Settings > Cloud Messaging”处手动启用小米云端短信，发送/接收者的电话号码是标识信息传递的主要依据。我们决定把小米云端短信设置为一项需要选择启用的服务，IMEI与IMSI也用于追踪设备的在线状况。或新建一个联系人时，
雨果巴拉原文：
- The primary identifiers used to route messages are the sender and receiver s phone numbers. IMEI and IMSI information is also used to keep track of a device's online status.
- When a user sends a text message, if there is an Internet connection available, the Cloud Messaging system will attempt to route the message via IP. If the receiver is offline (i.e. not immediately reachable via IP), the system falls back to sending a normal SMS message from the sender s device.
- When a MIUI user opens a text message or a phonebook contact, or creates a new contact, the device connects to the Cloud Messaging servers, forwards the phone number of that contact and requests the online status of the corresponding user, which is indicated by a blue icon when that user is online or gray icon if that user is offline (or is not a Cloud Messaging user). This allows the sender to immediately know whether they can text that user without incurring SMS costs.
- In any of these flows, the receiver s phone number is only used to look up online status and to route messages. No phonebook contact details or social graph information (i.e. the mapping between contacts) is stored on Cloud Messaging servers, and message content (in encrypted form) is not kept for longer than necessary to ensure immediate delivery to the receiver.
- The OTA system update made available today (Aug 10th) adds an extra layer of security by encrypting phone numbers whenever they are sent to Cloud Messaging servers.
- We will continue to make changes and improvements to this architecture as needed over time.
并感谢了提供了反馈建议的用户和媒体。设备会将涉及该联系人的电话号码发送给小米云端短信的服务器，在以上的任何情况中，当MIUI用户开启短信或打开联系人，
