ℹ️ Enable iCloud end-to-end encryption:

  • Nobody knows that, but iCloud actually supports end-to-end encryption (see “Advanced Data Protection for iCloud”) but it's disabled by default. If you care about data privacy, you should turn it on.
    • System settings → Apple ID → iCloud → Set Advanced Data Protection to On.
    • System settings → Apple ID → iCloud → Disable Access iCloud Data on the Web.
  • It supports almost all the native Apple apps, with the notable exceptions of iCloud Mail, Contacts, and Calendars. See official data protection matrix for more info.

Quality of life improvements
