Set up parental controls with Family Sharing on iPhone

Hello Kalanall, you are experiencing this because you are possibly now sharing the same cloud with your daughter, so some of your information available on your cloud would appear on her phone, you can apply any of these options and see if the problem will be resolved;

1. Delete your files on her phone and turn off iCloud sync.
2. You may have to erase your device on the iCloud website.

Hello,

Your appear to have two issues. One is your data transfer and the other Screen Time..

When you sign into an account on a device that was signed into a different account earlier, the device asks you if you wish to keep the information from the old account and mix it with the new account. You must have said "yes" and this has resulted in your information being merged with her information on her account. Since this information is then stored in iCloud, it appears on her phone signed into her account.

Screen Time settings are on an account, so I am not clear how her settings transferred to you since you are now signed into your account. However I do not use Screen Time so I don't know if somehow it transferred in a similar manner to the way your data transferred to her.

As for the data, you will have to ask her to delete that from her account. In theory if you had wanted to do what you did you would ideally have erased your phone completely before signing into her account, and then again before signing back into yours. You cannot casually sign out of one account on iPhones or iPads and into another.

Have you tried using your information to remove the Screen Time settings?
