My dad keeps getting all my apps that I download. why? My dad and I used to have the same Apple id, but recently I made his own (he didn't know how to work his) and I changed it on his phone. I kept mine on a new device. But he still keeps getting any app that I download. I don't know how to make it stop transferring all my data to him.
There are a few places Apple IDs can be set on a phone. Make sure that you changed his Apple ID in his iTunes &amp; App Store setting on his phone.

You shouldn't have to, but you may want to make sure that Automatic Downloads is not turned on also (in the same settings menu).
