• Manage parental controls: If you have children in the group, you can set limits on what they can access, such as age-appropriate content and app downloads.

Setting Up Ask to Buy

For parents, Ask to Buy is an important feature that prevents children from making unauthorized purchases in the App Store. When enabled, children must request approval before they can make a purchase, and the family organizer will receive a notification to approve or deny the request.

To enable Ask to Buy:

• Open Settings > Family Sharing > Select your child’s name > Ask to Buy.

This feature ensures that purchases are supervised, giving parents more control over what their children download or subscribe to.

Sharing iCloud Storage

With Family Sharing, you can share iCloud storage across family members, eliminating the need for everyone to purchase separate storage plans. Each family member has their own private space within the shared storage, so no one else can access their files.

To share iCloud storage:
