How come my contacts are also on my daughters phone?
HHow come my contacts are synced with my daughters phone?
iPhone 5s, iOS 8.3
They're probably synced via iCloud if you both are using the same Apple ID for things such as iTunes or the App Store. Try disabling iCloud on your daughters iPhone and see if that helps.
If she creates her own Apple ID, you too can share songs and Apps using family sharing: http://www.apple.com/icloud/family-sharing/?cid=wwa-us-kwg-features-com
