Apparently Apple can end-to-end encrypt your iCloud, but it’s opt in because they still want to profit off your data >_<
To enable this, go to Settings -> iCloud -> Advanced Data Protection
You need to have all the devices under your apple account to be fully updated, and you’ll need to remember a 28-key passphrase for recovery
I hate how big tech treats privacy as an afterthought. This should have been the default. But oh well. Spread the world people.
It’s not automatically on, but after the update it pops up on your screen telling you it is now available and asking if you want to opt in or not.
