Hi Eric
Thank you very much for your help with this it means a lot. I have been reporting via apple telephone support for almost a year that I suspect my devices are being managed. You are the first person to say and confirm that it is a third party app so thank you for letting me know.
First photo is after pressing the app. Then Data Access and Devices - Iphone and it shows tracking of activity data, i.e steps, resting energy etc similar to the Apple Health app. No there is no Siri & search nor notifications.
I wanted to see if the app was linked to my iCloud since showing in ‘apps using iCloud’. I signed out of iCloud and erased iPhone via erase all contents and settings. In the past after erasing iPhone the app appeared at some point but I was not signed into iCloud and did not back up when restoring. However I do remember it was after I either enabled or disabled screen time. This time it appeared when I deleted the health app and it took its place in settings. This all happened within 15 mins or less after erasing.
That Health Data app is shown in the main settings, apps using iCloud, privacy and security, iPhone storage, but not in battery usage and not in mobile data usage nor Home Screen. When I go to iPhone storage to try delete as you suggested the only option I have is ‘reinstall health app’.
I then went to Home Screen - ‘search’ and typed in the word profile. On its own shows the settings icon and next to it ‘Health’. When I type the word profile in the search bar of settings, it shows VPN & Device Management as expected and no other apps below except from that ‘Health Data’ app. This might mean absolutely nothing as the Apple Health App did the same before I deleted it but thought worth mentioning if Apps were managed as I’ve found configurations files on Mac for managed apps.
As far as I am aware, if there is a profile on your iPhone it will be in VPN & Device Management. I have no visible profiles however on my Mac I have a plist named Payloadmanifest with - orderedprofiles^hiddenprofiles - then states my iPhone network provider who I bought the phone from - then a string of letters.
I was asked by an apple adviser around the middle of last year if my Mac is owned by an organisation before I never knew much about mdm at that time but was starting to suspect it with all the sign in activity that wasn’t me.
I have been referencing what I’m finding with apple developers site as much as I can on - profile configuration references and mobile device management protocol. As I‘ve been seeing on my Mac and iphone information regarding enterprise then all the management configurations, restrictions and the .mobileconfig files for the configurations on Mac only. However this isn’t something I fully understand if much at all but I need this to stop as it’s taken over every part of my life and my work is fully online which I can’t do with this going on. Either way this isn’t right. Two senior advisors have said it’s in the hardware when I’ve explained more information so I don’t know what to do.
I will contact my phone provider regarding the phone as they never did the investigation they said they wanted to do.
During Xmas when I was still at this and still am, I came across on my Mac
is_supervised_cloudconfigurationuicomplete_configurationsource\
allowpairing_postsetupprofilewasinstalled
I may be best doing separate posts on everything as I’ve also found a hidden administrator in users and groups if go a different route and not via system preferences.
If you know what I can do about that app or where to go from here I’d be very thankful for your advice.
Thank you very much again
