If you want, you can disable access to your mail, contacts, calendar, photos, notes, reminders, files, and documents on iCloud.com. Here's how to do it.
You can increase privacy by completely disabling iCloud Web and cutting off data access using a web browser
There are many people out there who rely on Apple services to get things done. If you have an iPhone in your pocket, then you already use apps like Reminders or Notes. You might have taken things further by opting for iCloud Photo Library to keep your photos and videos synced to Apple's server as well.
If you ever need to access your data, there are multiple ways of doing that too. You can access it on your iPhone, iPad, and Mac. But, little do people know that you can even access your iCloud data right from iCloud.com on the web, which is a huge convenience. This especially comes in handy if you have a Windows PC or just don't feel like using your device at all to catch up on things.

However, some might even see this as a privacy risk. Just think about it, you leave your Mac or PC unattended for a moment, and someone can actually go through your stuff, including photos, videos, notes, mail, etc., if you left your Apple ID signed in to iCloud web.
Luckily, you have the option to disable access to all your iCloud data on the web. You can disable this feature right from your iPhone, iPad, or Mac. Here's how to do it right away.
Note: Please make sure you have the latest iOS, iPadOS, and macOS update installed in order to disable iCloud web from your devices.

Step 4. Scroll down and disable the 'Access iCloud Data on the Web' feature

While this is a great way to enhance your privacy, do keep one thing in mind - if you have just one Apple device and you lose it, you won't be able to access your data on the web at all. Be very careful before you disable access to the iCloud web.
