Family sharing
Can my family see my photos using the 200GB family share

Question marked as
No. When you use Family Sharing, every member’s data and photos remain private. The exception would be if you decide to create a shared photo album. In that case others in the family will see those photos.

Share an iCloud storage plan with your family.
Your entire family can share a single iCloud storage plan large enough to store everyone’s photos, videos, and files. Each person’s files and documents remain private, but it’s easy to see how much storage everyone is using. If you need more space, you can upgrade to a larger plan at any time.
