ICloud
iCloud Drive with iCloud+
US plans run from 50 GB for $0.99 a month to 2 TB for $9.99, with 6 TB and 12 TB tiers above, and any plan can be shared with up to five other family members. For an all-Apple household, one 2 TB plan covering everyone's files and phone storage is among the cheaper arrangements here.
The privacy story depends on a switch. Turn on Advanced Data Protection and iCloud Drive becomes end-to-end encrypted, with the keys on your trusted devices. It is off by default, needs a recovery contact or recovery key, and a shared folder keeps that protection only when every participant has it on. Homes that mix Android phones and Windows PCs will usually be better served by Google Drive or OneDrive.
