How can I tell if my iPhone is linked to a work profile?

Go to Settings/General/VPN & Device Management. If you have a management profile it is controlled through Mobile Device Management.

It may also be if you have a business or school Microsoft Exchange email account on the phone.

Your phone can’t be linked to a hacker unless you installed a profile provided by the hacker (same location as above).

It is a total mystery to me what you are seeing. Can you post a screen shot?

I don’t know if your word processing question is related, but there are several word processors for iPhones, including the built in Apple Pages and Microsoft Word from the App Store.

I also don’t see how it is related in any way to work profiles, the subject of this thread.
