Photos privacy on iPhone

Quick answer

Use the Hidden collection for pictures and videos; app visibility and photo-library access are separate controls.

Review iCloud Photos, Shared Library, Shared Albums and exports independently. Hiding a photo can follow it across your own synced library.

Task	Method	Scope
Hide apps	Authenticated Hidden folder	Preinstalled apps and some default apps cannot be hidden. Records can remain in Settings, purchase history and family controls. The setting does not sync to other devices.
Lock apps	Device authentication	Not every app can be locked. Device authentication is not an independent password for each app, and the lock applies only to this device.
Find hidden apps	App Library inspection	This inspects the phone you can authenticate to. It does not reveal another person’s private app activity or recover a deleted app’s data.
Unhide apps	Reverse the app hiding action	Unhiding does not reinstall an app that was deleted, restore its account, or recover files removed inside the app.
Hide photos	Photos Hidden collection	Hidden is part of Photos, not an independent vault password. Hiding does not recall exports, messages or copies saved by someone else.
Hide notifications	Lock Screen notification review	A display change does not remove information inside an app or end account access elsewhere.
Restrict apps	Screen Time access restrictions	Restrictions do not delete an installation, erase account data or guarantee invisibility. Allowed exceptions and administrative recovery affect the result.

Apple says apps that come installed cannot be hidden using this downloaded-app workflow. Check the app’s own content controls instead.

No. Home Screen removal, hiding and deletion are separate actions.
