My contacts have synced with someone else on our family plan? How can I get rid of them

Hi AStrader51,

Thanks for posting in Apple Support Communities. We understand that your contacts are syncing with your daughter's device. This can happen if you share an Apple ID. We advise that each family member has their own Apple ID on their own device. You have the option to create an Apple ID specifically for a child. Family Sharing and Apple ID for your child has some guidance on creating a child Apple ID account.

Once everyone has their own Apple ID, you can sign out of the device that you wish not to sync your information to and sign in with the newly created Apple ID.

Warm regards.

Hi AStrader51,

With contacts being synced on both devices, is it possible that one of you added an email account to your device that syncs contacts? You can check for any shared email accounts in Settings > Mail > Accounts.

If you two share a computer, it is possible that you may have synced your contacts using iTunes. This could have happened while trying to sync other information. Sync app info from your PC to devices with iTunes has the steps that may have been performed when syncing occurred.

Warm regards.
