Can my parents see the apps I download? ( iPhones by T-Mobile)

I just want to know if they can see the apps I download. Our plan is shared.
Our Apple ID is different of course and my phone has a pin, but is there a way the can find out thru the account or something else?

Yes. If they do not go directly to their phones, then they definitely go to the commuter files in I Tunes, that save all duelists for sharing in the same plan. No way around it.

Your shared phone plan wouldn't show what apps you download to your individual phone.

No

Yes, easily.

No. Your parents will not be able to see what apps you are downloading. If you have the same Apple ID… Then yes.

But as long as you have a separate Apple ID then only the holder of that account will be able to see downloaded apps.

If you have tech savvy parents then they could have jailbroken your device and added some parental control software. But that is unlikely lol.

A shared data plan doesn't mean it literally share everyone's data. As long as your Apple ID is different from your parents, you are safe. The only way is to somehow get your Apple account password, which is not possible for them.

Are you downloading paid apps using an iTunes connected to a credit card? If so, there there's a detailed record of every app you downloaded since owning that phone on the iTunes account associated with the credit/debit card listed as payment method.
