Seems some of iCloud is end-to-end encrypted. These features and their data are transmitted and stored in iCloud using end-to-end encryption:
* Apple Card transactions
* Home data
* Health data
* iCloud Keychain
* Maps Favorites, Collections and search history
* Memoji
* Payment information
* QuickType Keyboard learned vocabulary
* Safari History and iCloud Tabs
* Screen Time
* Siri information
* Wi-Fi passwords
* W1 and H1 Bluetooth keys
Things that are not e2e: photos, iMessage, Notes, Mail, Contacts, and others.I'm wondering, are the Safari cookies e2e encrypted?
