What is iCloud Notes?
You can use Notes on iCloud.com to capture a quick thought or save something important or interesting for later, and then view those notes in the Notes app on your iPhone, iPad, iPod touch or Mac. You can also use Notes on iCloud.com to view and edit notes you created in the Notes app.
Note: you can only use Notes on iCloud.com to work with notes stored in iCloud, not the notes in other accounts you may have, such as a Yahoo or Google account. However, on your iOS device, iPadOS device or Mac, you can set up the Notes app to use iCloud and other accounts.
If you are using another iCloud feature, you can switch to Notes by tapping the feature’s name at the top of the iCloud.com window.
The first time you use Notes on iCloud.com, you may get a message that says you need an iCloud email address. If so, you have not set up the iCloud Notes app on your iOS device, iPadOS device or Mac. Sign in with your Apple ID on your iOS device, iPadOS device or Mac, then turn on Notes (see Turn iCloud features on or off).
The iCloud Notes features you have depend on the following:
If your device has iOS 9, iPadOS 13, OS X 10.11 or later: You can use upgraded iCloud notes.
If your device has earlier versions of iOS or OS X: you do not have access to upgraded notes. Choose an iCloud email address for a free iCloud email account. This account will be used for your iCloud notes.
If you have not upgraded your notes, you cannot view them in iCloud.com on an iPhone. Sign in to iCloud.com using a web browser on a Mac or Windows computer to access them.
Note: To use all iCloud Notes features, upgrade your iCloud Notes account and upgrade your devices so they use iOS 9, iPadOS 13, OS X 10.11 or later. See the Apple Support article Upgrade your Notes app.
