Family Sharing privacy

Hey there hanumanhopkins,

Thanks for reaching out to Apple Support Communities. We're happy to provide some assistance.

As mentioned in Share iCloud+ with your family - Apple Support, "When you share an iCloud+ subscription, everyone in the family group uses their own account. That way your photos, documents, and other information stay private, even though you're sharing access to the service. You simply share the features and space available in iCloud+ with your family members, so you only have one plan to manage."

Hope this answers your question.

Have a great day!
