MDM profiles, device configuration capabilities, and certain VPN configurations are restricted to enterprise and specific approved use cases. Consumer apps that try to use these features will get rejected.
What Apple said
“Your app attempts to install configuration profiles, use Mobile Device Management features, or modify device settings in ways not permitted by App Store guidelines. These capabilities are restricted to specific enterprise and managed device scenarios and cannot be distributed through the App Store to general consumers.”
Apple tightly controls which apps can manage or configure iOS devices. MDM profiles, certificate installation, certain VPN configurations, and screen time management features are restricted to enterprise distribution, MDM providers, or Apple-approved categories. A consumer app that tries to use these capabilities will get rejected — even with legitimate intentions.
While you're at it — Apple also requires these pages for every app.
Fix this rejection, then make sure you're covered on the compliance side too. Apple requires every app to link to a hosted Privacy Policy, Terms of Service, Support page, and Data Deletion page. No link means another rejection — just for a different reason.
