iPhone Privacy Settings Guide: What to Turn On and Why

The iPhone privacy settings that matter most are in three places: Settings > Privacy & Security, Settings > Face ID & Passcode and the lock options inside Photos and on each app. If you only have ten minutes, work through this list:

1. Run Safety Check in Settings > Privacy & Security to see who and what has access to your information.
2. Review app permissions in the same screen, and turn on App Privacy Report to see what apps actually used.
3. Turn on Stolen Device Protection in Settings > Face ID & Passcode.
4. Set notification previews to When Unlocked, so messages don’t show on the Lock Screen.
5. Keep the Hidden album locked in Settings > Apps > Photos.
6. Lock or hide apps that hold private things, with Require Face ID (iOS 18 and later).
7. Stop the Camera from saving your location if you share photos with people you don’t know.

One thing ties all of these together. Nearly every lock on iPhone falls back to your device passcode, so anyone who knows it can get past most of them. Keep the passcode to yourself and treat it as the real key.

This page is the hub for our iPhone privacy guides. Each section below gives the essentials with links to Apple Support, then points to the full guide for that topic.

Hide and lock photos

Photos has one built-in privacy feature, the Hidden album. When you hide a photo or video, it leaves your Library, your other albums and the Photos widget. Since iOS 16, Apple locks the Hidden album by default, so it needs Face ID, Touch ID or your passcode to open. You can also switch the album off entirely in Settings > Apps > Photos by turning off Show Hidden Album.

To hide something, touch and hold it in Photos, tap Hide and confirm. The steps for single photos, many at once, finding them again and unhiding are in how to hide photos on iPhone. Videos work the same way, with a few differences around storage and iCloud covered in how to hide videos on iPhone. If you can’t find the album, where the Hidden album is on iPhone covers iPhone, iPad and Mac and the usual reasons it goes missing.

Apple documents no separate “private album” feature, so the Hidden album is the private album. How to make a private photo album on iPhone walks through setting it up and removing it from view. iOS also has no password you can put on a single photo. The built-in alternatives are the Hidden album, a locked note and locking the Photos app, compared side by side in how to lock photos on iPhone.

Know the limits before you rely on it. The Hidden album uses your passcode as the fallback, and if you use iCloud Photos, Apple says photos you hide on one device are hidden on your other devices too, so they stay part of your iCloud library. Is the iPhone Hidden album private? goes through who can see hidden photos in each situation.

Documents and scans need a different approach, since the Files app has no lock for a single folder. How to hide files and folders on iPhone covers the options.

Hide and lock apps

In iOS 18 and later you can put Face ID, Touch ID or your passcode in front of an app. Touch and hold the app on the Home Screen and tap Require Face ID. Apple says information from a locked app doesn’t appear in places like search, notifications, Siri suggestions or your call history. Some built-in apps can’t be locked, including Calculator, Camera, Clock, Contacts, Find My, Maps, Shortcuts and Settings. How to lock apps on iPhone has the steps, the full limits and the older Screen Time options.

Hiding goes one step further. The same menu offers Hide and Require Face ID, which removes the app from the Home Screen, App Library and search and moves it to a locked Hidden folder at the bottom of App Library. Apple notes that the locked or hidden status applies only to that iPhone and doesn’t sync with iCloud. A hidden app’s name can still show up in places such as Settings > Screen Time and your App Store purchase history, as how to hide apps on iPhone explains.

To get an app back, open App Library, tap the Hidden folder, authenticate, then touch and hold the app and tap Don’t Require Face ID. Apps can also go missing because they were removed from the Home Screen or sit on a hidden Home Screen page. How to find and unhide apps on iPhone covers each case, including what to check if you think someone else hid an app on your phone.

Locking an app protects the whole app, not one album or one conversation inside it. Anyone who gets past the lock, for example with your passcode, sees everything the app holds.

Messages, notes and browsing

Messages has no hidden folder for individual conversations. What you can control is where the text shows up. In Settings > Notifications, tap Show Previews and choose When Unlocked or Never, and Apple’s notification settings guide notes you can override this for individual apps. You can also hide alerts for one conversation, filter texts from unknown senders, have old messages delete themselves, or lock the Messages app. How to hide text messages on iPhone covers each option and what it still leaves visible.

Deleted texts don’t vanish at once. Apple says you can recover messages and conversations you deleted within the last 30 to 40 days from Recently Deleted. If you use Messages in iCloud, a deletion on your iPhone also deletes the message on your other devices where it is turned on.

Notes lets you lock individual notes with your device passcode or a separate Notes password, plus Face ID or Touch ID. Apple says both options use end-to-end encryption for iCloud accounts. A locked note’s title stays visible in the list, and some notes can’t be locked at all, such as notes with video, audio or PDF attachments. If you forget a custom Notes password, Apple can’t recover it for you. How to lock notes on iPhone has the setup and the workarounds for hiding notes.

For Safari, you can clear history in Settings > Apps > Safari > Clear History and Website Data. Apple says this doesn’t change your AutoFill information. How to clear search history on iPhone also covers removing one site at a time and hiding recent searches. Private Browsing keeps Safari from saving history in the first place, and since iOS 17 private tabs can lock behind Face ID, Touch ID or your passcode. How to turn Private Browsing on or off on iPhone explains the black address bar, the lock and what Private Browsing does not hide from your network.

If you would rather people not see when you have read their messages, turn off read receipts on iPhone, for everyone or for one conversation.

Security and settings

Most system-level privacy controls live in Settings > Privacy & Security. Apple’s iPhone guide says to tap a category, such as Calendars or Motion & Fitness, to see the apps that requested access and turn access on or off for each. Photos, Contacts, Camera and Microphone are worth checking first.

To see what apps did with that access, turn on App Privacy Report at the bottom of the same screen. Apple says it shows how many times and when apps accessed privacy-sensitive data or sensors in the past 7 days, which domains they contacted, and that the data is encrypted and stored only on your device. It needs iOS 15.2 or later and only starts collecting after you turn it on, so check back in a few days.

Safety Check is for reviewing who you share with. It’s at Settings > Privacy & Security > Safety Check on iOS 16 or later. Apple’s Personal Safety guide describes two paths. Emergency Reset immediately resets sharing for all people and apps. Manage Sharing & Access lets you review people, apps and account security one at a time. It’s worth running even if nothing is wrong, since it shows which devices are signed in to your Apple Account.

Location has several separate switches. Settings > Privacy & Security > Location Services turns it off for the whole phone or for one app, sharing with friends in Find My is a separate setting, and photos can carry the place they were taken. Apple says photo location is collected only if the Camera app has access to Location Services, and you can turn off Location in the Share Sheet’s Options before sending a photo. How to turn off location on iPhone goes through all of them.

Stolen Device Protection guards against someone who has watched you type your passcode and then takes the phone. Apple says it’s available in iOS 17.3 or later and is turned on in Settings > Face ID & Passcode. Away from familiar locations such as home or work, actions like using saved passwords or erasing the iPhone need Face ID or Touch ID with no passcode fallback, and changing your Apple Account password also needs a one-hour wait. It requires two-factor authentication, a passcode and Find My.

Your saved passwords sit in the Passwords app on iOS 18 and later, or in Settings > Passwords on iOS 17 and earlier, according to Apple’s overview. How to find saved passwords on iPhone covers viewing, copying, Wi-Fi passwords and what the security alerts mean.

The full walkthrough, including which actions get the security delay, is in Stolen Device Protection on iPhone.

New iPhone, storage and recovery

Switching phones is when private files get lost. The easiest way to move everything is Quick Start, with the old phone next to the new one. You can also restore from an iCloud backup or a computer backup during setup. How to transfer everything from one iPhone to another compares the three methods and lists what doesn’t come across on its own.

Photos in the Hidden album travel with iCloud Photos because they are part of your iCloud library. Photos in a vault app live in that app’s own storage, so whether they arrive depends on the app’s backup. How to transfer a photo vault to a new iPhone has a checklist to run while the old phone still has everything on it.

Before you sell, trade in or hand over an iPhone, turn off Find My, which removes Activation Lock. How to turn off Find My iPhone covers doing it on the phone or remotely, and why Stolen Device Protection can block the switch. Then erase it in Settings > General > Transfer or Reset iPhone > Erase All Content and Settings, as Apple’s erase instructions describe. How to erase an iPhone gives the checklist in the right order and how to erase a lost phone remotely.

If something is already gone, start with Recently Deleted. Apple keeps deleted photos and videos there for 30 days, then deletes them permanently. How to recover deleted photos from iPhone and how to recover deleted text messages on iPhone take you from the easy fix to restoring a backup, which replaces what is currently on the phone. If you are locked out of a vault app, private photo vault recovery explains what can and cannot be recovered.

To keep a copy of your photos outside the phone, transfer photos from iPhone to a computer. When the phone runs out of space, free up storage on iPhone without losing anything you want to keep.

Photo vault apps

Everything above lives inside Apple’s apps and leans on your passcode. A photo vault app keeps files in its own storage behind its own lock, so a photo in the vault isn’t in your Photos library at all. That helps when other people know your passcode or you share an Apple Account, and it shifts the responsibility for the lock and the backup to you.

Vault apps differ a lot in how they store files and what happens when you forget the code. How to choose an app to hide photos gives nine checks you can run yourself, from encryption and recovery to export and the App Store privacy label. Many vaults disguise themselves as a calculator. Calculator vault apps explains what that disguise hides from a glance at your Home Screen and what it does nothing about.

Before you put your only copies anywhere, test the backup and the export. A vault you can’t restore or get files out of is a risk, whatever lock it has.

Where Forevault fits

Forevault is our vault app for iPhone, for the photos and videos you don’t want in your main library. Files are encrypted on the device with AES-256-GCM. It opens with a pattern on a 5×5 grid, a passcode or a password, and Face ID is optional. You can keep separate vaults for different patterns, and the lock screen does not list them. There is a 12-word recovery phrase and an encrypted backup to your own iCloud with “Test a restore”, so you can check it works before you switch phones. Export to Photos or Files is always free. There is no account and no data collected. The free tier holds 100 photos, 10 videos and 3 vaults, and there is no calculator disguise. It protects against someone holding your phone, not forensic analysis. Questions go to the support page. Download Forevault on the App Store.

Frequently asked questions

What privacy settings should I change on my iPhone?

Start with Safety Check and the app permissions in Settings > Privacy & Security, then turn on App Privacy Report and Stolen Device Protection. Set notification previews to When Unlocked, keep the Hidden album locked in Settings > Apps > Photos, and lock any app that holds private things with Require Face ID.

How do I make my iPhone more private?

Limit what apps can reach, limit what shows on the Lock Screen, and lock what is inside. Review permissions per category in Privacy & Security, hide message previews, hide or lock photos and apps, and clear or avoid Safari history with Private Browsing. Keep your passcode private, because most of these locks fall back to it.

Where are the privacy settings on iPhone?

Most are in Settings > Privacy & Security, which holds Location Services, app permissions by category, App Privacy Report and Safety Check. Stolen Device Protection is in Settings > Face ID & Passcode. Photo, Notes and Safari options are under Settings > Apps.

What does Safety Check do on iPhone?

It reviews who and what has access to your information. Emergency Reset stops sharing with all people and apps at once, and Manage Sharing & Access lets you go through people, apps and account security one by one. It needs iOS 16 or later.

Can someone see my hidden photos or locked apps if they know my passcode?

Yes. The Hidden album and locked apps both accept your device passcode. Stolen Device Protection removes the passcode fallback for locked apps when your iPhone is away from familiar locations, but at home the passcode still works.

Do hidden apps and hidden photos sync to my other devices?

Hidden photos do if you use iCloud Photos, and they stay hidden on your other devices. Locked or hidden apps don’t. Apple says that status applies only to the iPhone where you set it.
