iCloud 在 iPhone 和Mac(Mac)上发挥着重要作用。它不仅可以在设备之间无缝同步您的照片、笔记、提醒等，而且还提供必不可少的备份功能。但是，如果您想关闭 iCloud 怎么办？
无论是为了节省 iCloud 存储空间还是保护您的隐私，都可以禁用特定的 iCloud 功能，甚至禁用 iCloud 本身。我们将在下面深入研究并检查它是如何工作的。
什么是 iCloud？
iCloud 是基于云的功能的组合，可协同工作以同步和备份您的数据。例如，iCloud 照片(iCloud Photos)允许您将照片和图像安全地存储在云中，而iCloud Drive可以上传文件并让您的文件跨设备可用。
此外，本机应用程序（例如通讯录、备忘录和提醒事项(Reminders)）使用 iCloud 让您在您拥有的每台 iOS 和 macOS 设备上的活动保持最新。
在 iPhone 上，iCloud 甚至允许您创建设备的完整备份。然后，您可以使用它来恢复一切，以防出现问题。如果您丢失了 Apple 设备，它还提供了通过 Find My 跟踪它们的方法。(track Apple devices via Find My)
最好的事情是您不必手动设置 iCloud。只需(Simply)使用Apple ID登录即可在 iPhone 或(Apple ID)Mac上激活它。
但是，您可以选择禁用个别 iCloud 功能或停止应用程序使用该服务来同步或备份数据。您还可以根据需要退出您的Apple ID并关闭 iCloud。
为什么你应该关闭选择(Select)iCloud 功能
iPhone 和Mac都允许对 iCloud 在您的设备上的工作方式进行精细控制，因此您可以快速停用任何 iCloud 功能。这就是您可能想要这样做的原因。
停止数据同步(Stop Data from Syncing)
iCloud 在设备之间同步来自各种应用程序的数据，例如您的照片、提醒事项和日历事件。但是，如果您想将特定应用的活动与其他设备分开，则必须阻止它使用 iCloud。
例如，如果您想阻止您的 iPhone 从其他设备上传或下载便笺，则在 iOS 设备上停用便笺应该会有所帮助。
节省 iCloud 存储空间(Conserve iCloud Storage)
iCloud 提供 5GB 的免费云存储数据。但是，这可以很快填满。如果您有多个设备绑定到同一个Apple ID(Apple ID)，即使 iCloud 的付费存储计划也不会持续很长时间。
因此(Hence)，在特定设备上关闭存储空间最密集的 iCloud 功能（例如 iCloud照片(Photos)和 iCloud Drive）有助于节省存储空间。(Drive—on)如果您决定仅将 iPhone 备份到计算机，(back up your iPhone to a computer)您还可以禁用 iCloud备份(Backup)。
为什么你应该完全关闭 iCloud
iCloud 提供了许多优势，但您也可能会遇到要求您在 iPhone 或Mac(Mac)上将其完全关闭的情况。
您计划出售您的设备(You Plan to Sell Your Device)
如果您打算出售 iPhone 或Mac，最好完全关闭 iCloud。这会自动停用Find My，进而禁用名为Activation Lock的功能。但是，您必须通过出厂重置设备(factory resetting your device)来跟进，因为这会将所有本地存储的数据从其内部存储中擦除。
保护您的隐私(Preserve Your Privacy)
Apple通过加密 iCloud 中的内容采取坚定的立场来保护用户隐私。但是，如果您想防止任何泄露数据的机会，您可能希望停用 iCloud。
但是，这确实是以停用Find My(Find My)为代价的。该功能带来的防盗功能是不可或缺的。
此外，关闭 iCloud 不会删除您已存储在其中的数据。您必须单独管理（更多内容请参见下文）。

转到设置(Settings )> Apple ID > iCloud >在 iPhone 上管理 iCloud或(Manage iCloud)系统偏好设置(System Preferences )> Apple ID >在Mac上(Mac)管理(Manage )，您应该能够按功能或应用程序删除数据。此外，您还可以通过网络浏览器登录iCloud.com来删除各种形式的数据。(iCloud.com)
即使在完全关闭 iCloud 之后，您也可以通过单独登录来继续将Apple ID与FaceTime、App Store和 iMessage 等服务一起使用。(App Store)
How to Turn Off iCloud and What It Means If You Do
iCloud plays a significant role on the iPhone and Mac. Not only does it sync your photos, notes, remindеrs, etc., seamlessly betwеen deνiceѕ, but it also serves an essentіal backup function. But what if you want to turn off іCloud?
Whether that’s to conserve iCloud storage or to preserve your privacy, it’s possible to disable specific iCloud features—or even iCloud itself—altogether. We shall dig in and check how that works below.
What Is iCloud?
iCloud is a combination of cloud-based features that work in tandem to sync and back up your data. For example, iCloud Photos allows you to keep photos and images stored safely in the cloud, while iCloud Drive uploads and makes your files available across devices.
Furthermore, native apps (such as Contacts, Notes, and Reminders) use iCloud to have your activity up-to-date on every iOS and macOS device you own.
On the iPhone, iCloud even allows you to create a complete backup of the device. You can then use it to restore everything in case something goes wrong. It also provides the means to track Apple devices via Find My if you ever lose them.
The best thing is that you don’t have to set up iCloud manually. Simply signing in using an Apple ID is all you need to do to activate it on your iPhone or Mac.
However, you can choose to disable individual iCloud features or stop apps from using the service to sync or back up data. You can also sign out of your Apple ID and switch off iCloud should you want.
Why You Should Turn Off Select iCloud Features
Both the iPhone and the Mac allow for granular control over how iCloud works on your device, so you can deactivate any iCloud feature quickly. Here’s why you may want to do that.
Stop Data from Syncing
iCloud syncs data from various apps—such as your photos, reminders, and calendar events—between devices. But if you want to keep your activity for a specific app separate from the rest of your devices, you must stop it from using iCloud.
For example, if you want to stop your iPhone from uploading or downloading notes from other devices, deactivating Notes on the iOS device should help.
Conserve iCloud Storage
iCloud offers 5GB of free cloud-storage data. However, that can fill up quickly. Even iCloud’s paid storage plans don’t last long if you have multiple devices tied to the same Apple ID.
Hence, turning off the most storage-intensive iCloud features—such as iCloud Photos and iCloud Drive—on select devices can help conserve storage. You can also disable iCloud Backup should you decide to back up your iPhone to a computer only.
Why You Should Turn Off iCloud Completely
iCloud provides many advantages, but you may also come across instances that require you to turn it off entirely on your iPhone or Mac.
You Plan to Sell Your Device
If you plan to sell your iPhone or Mac, it’s a good idea to turn off iCloud completely. That automatically deactivates Find My, which in turn disables a feature called Activation Lock. However, you must follow up by factory resetting your device since that wipes all locally stored data off its internal storage.
Preserve Your Privacy
Apple takes a solid stance in favor of user privacy by encrypting contents in iCloud. But if you want to prevent any chances of compromising your data, you may wish to deactivate iCloud.
However, that does come at the cost of deactivating Find My. The anti-theft capabilities that the feature brings to the table can be indispensable.
Additionally, turning off iCloud won’t delete data that you’ve already stored in it. You must manage that separately (more on that further below).

You Must Manage Your iCloud Data Separately
If you disable a specific iCloud feature or sign out of iCloud, that won’t delete any data stored in iCloud itself. Instead, you must do that manually from another device that you’ve signed in with the same Apple ID.
Go to Settings > Apple ID > iCloud > Manage iCloud on an iPhone or System Preferences > Apple ID > Manage on a Mac, and you should be able to delete data by feature or app. Additionally, you can also delete various forms of data by signing into iCloud.com via a web browser.
Even after turning off iCloud completely, you can continue using your Apple ID with services such as FaceTime, the App Store, and iMessage by signing into them separately.
