Kathy writes in with a problem and a request:
In my history, I see apps I did not install nor do I think are on any device we own. Can I know which device they were supposedly installed on and how can I erase them on my purchases?
For the first, it’s hard to know. Apps associated with an iTunes account should only appear there if they were obtained for free or purchased. It’s definitely possible that you or someone in your family selected apps by unintentionally clicking, or the apps are from so far in the past, you forgot you ever bought them. I have apps on my account that are seven years old, and I have no recollection of ever interacting with it.
