Hi shrishd,
That could be a possibility, especially if the Ask to Buy feature is on.
I'd ask your dad.
Here's more info on the topic:
To see if you can share an app, go to its product page in the App Store and scroll down to Information. Then see if it says Yes or No in the Family Sharing section.
Some apps may not be enabled for Family Sharing. If you’ve acquired one of these apps, you can see it in your purchase history, but your family members won't be able to see or redownload it.
If a family member has hidden one of their items, no one in their family can see it. Your family member can unhide those items if they want to.
To access your family's shared content, you need an iPhone, iPad, or iPod touch using iOS 8 or later, or a Mac using OS X Yosemite or later. If you're using an older device, you won’t see your family’s shared content. If you're using an Apple TV, you can see shared movies and TV shows only.
iOS 8 and OS X Yosemite are required to set up or join a Family Sharing group. See the system requirements for Family Sharing.
Family Sharing requires a personal Apple ID signed in to iCloud and iTunes. If your family has purchase sharing turned on, music, movies, TV shows, and books can be downloaded on up to 10 devices per account, five of which can be computers. Not all content is eligible to be shared. Content can be hidden by family members; hidden content is not available for download. Content downloaded from family members or acquired via redemption codes is not subject to Ask to Buy.
