## Privacy tasks

| Task | Method | Scope |
|---|---|---|
| [Hide apps](/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](/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](/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](/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](/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 message previews](/hide-messages) | Message notification privacy | Notification preferences do not erase messages, recipient copies, saved attachments or other signed-in devices. |
| [Hide notifications](/hide-notifications) | Lock Screen notification review | A display change does not remove information inside an app or end account access elsewhere. |
| [Restrict apps](/block-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. |

## Questions

### Can Messages be hidden with the iOS Hidden folder?

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

### What remains outside the app lock?

Shared With You changes where supported attachments are surfaced. It does not delete a conversation or revoke the recipient's copy.

### Does removing the icon delete the app?

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