iCloud sharing using
i have 2T storage for my I cloud. If I share it with my kids and wife, are they can access and see my pics and files stored in the cloud? If yes, how can I share it with my family without anybody access my file???
No. See the following from Share an iCloud storage plan with your family - Apple Support
When you share a storage plan, your photos and documents stay private and everyone keeps using their own accounts with iCloud—just like when you have your own storage plan. You simply share the space available in the iCloud storage plan with your family members, so you only have one plan to manage.
