Review and delete configuration profiles
Device configuration profiles, mobile device management (MDM) tools, and custom apps may be used by organizations (like schools and businesses) to manage or supervise devices, and these tools may allow access to data or location information on the device.
A configuration profile can manage a variety of settings for user accounts, along with other device functionality. Configuration profiles can work on iPhone, iPad, Mac, Apple TV, and Apple Watch.
If you see a configuration profile installed on your device that isn’t supposed to be there, you may be able to delete it, depending on who installed it. Doing so deletes all of the settings, apps, and data associated with the configuration profile.
IMPORTANT: Before making changes or deleting information, consider potential impacts to your safety and privacy.
