iPhone Privacy Settings to Change Today

This is a quick pass through the iPhone settings that control who can see your data, what shows on a locked screen, and who can reach you.

It should take around fifteen minutes, and each step comes from Apple's iPhone User Guide.

It covers the parts our ranked guide does not: app access, the Lock Screen, calls, texts, AirDrop and Wi-Fi. Checked on October 22, 2026 against the iOS 27 version of the guide.

The short answer

Open Settings, then Privacy & Security, and look at each category of data and each hardware feature. Turn off access for apps that do not need it. Then work through the Lock Screen, Phone, Messages and AirDrop settings below.

Apple lets you change any permission later, so nothing here is permanent. If a choice breaks an app, turn the permission back on.

What this guide adds to our ranked list

Our guide to iPhone privacy settings to change ranks the settings with the biggest impact: app tracking, Location Services, advertising and Apple Intelligence. Read that first if you have time for only one.

This page goes further down the list. It is a checklist you can finish in one sitting, built around what other people can see and do on your phone.

Do these first

1. Open Settings and choose Privacy & Security.
2. Tap each category, such as Calendars, Reminders or Photos, and review the apps listed.
3. Turn off access for any app that does not need it.Off
4. Tap Camera, Microphone, Bluetooth and Local Network and repeat.
5. Go to Settings and tap Face ID & Passcode, then review Allow Access When Locked.
6. Go to Settings, tap Apps, tap Phone, and turn on call filtering.
7. Open Control Center and set AirDrop to Contacts Only.

Review which apps can see your information

Apple says you control whether third-party apps can access information in Contacts, Photos, Calendar and other apps. The first time an app wants information from another app, you get a request with an explanation.

To review your choices, go to Settings, then Privacy & Security, and tap a category. A list shows the apps that requested access, and you can switch access on or off for any of them.

Permissions for the camera, microphone and more

Apple also makes apps request permission before they use the camera or microphone. Other hardware follows the same rule, including Bluetooth, motion sensors and devices on your local network.

To review them, go to Settings, then Privacy & Security, and tap Camera, Bluetooth, Local Network or Microphone.

Apple says a green dot shows while an app uses the camera, and an orange dot shows when it uses only the microphone.

Control Center also displays a note at the top if an app recently used either of them.

iPhone privacy settings photos not working

If an app cannot see your photos, look in the same place. Go to Settings, Privacy & Security, then Photos. The list shows only apps that requested access, so an app missing from it has not asked yet.

If the app is listed with access off, turn it on. If it is not listed, open the feature in the app that needs photos so that it can ask.

Update the app, then force it closed and open it again, or restart the iPhone.

Some apps let you pick individual photos instead of asking for access to your whole library, so a missing entry does not always mean something is broken.

I could not confirm that behavior in Apple's iPhone guide, so check the app's own help.

See how apps use their permissions

Go to Settings, Privacy & Security, then App Privacy Report. Apple says it reports how apps use the permissions you gave them and also lists their network activity.

Apple's support article says it shows access to data and sensors over the past 7 days, and lists domains your apps and the sites inside them contacted. The report stays empty until you turn it on.

A domain in the report does not by itself prove that an app sold your data or tracked you. Treat it as a prompt to investigate further.

The same screen lets you switch the report off and erase its data. It is a good way to spot an app that uses a permission far more than you expected.

Lock Screen: what people can see without your passcode

You can allow a few features, such as Control Center, widgets and media controls, to work from the Lock Screen. Go to Settings, then Face ID & Passcode (or Touch ID & Passcode), and look under Allow Access When Locked.

Apple notes that switching off Lock Screen access keeps a person who picks up your iPhone from seeing details such as a coming event in the Calendar widget. The cost is that you lose quick access to it yourself.

Phone calls: filter unknown and spam callers

Go to Settings, tap Apps, then tap Phone. Apple lists two filters. Unknown Callers takes calls from numbers you have not saved out of Recents and puts them in an Unknown Callers list.

Spam quiets calls that your carrier flags as likely spam or fraud, routes them to voicemail and lists them under Spam.

Call Screening for unknown numbers

Call Screening picks up calls from unknown numbers for you, without interrupting what you are doing.

When the caller states a name and a reason, your iPhone rings and displays what they said so you can choose whether to pick up.

In the same Phone settings, Apple offers three choices. Never turns screening off.

With Ask Reason for Calling, unknown callers must state why they are calling before your phone rings. Silence silences calls from unsaved numbers and sends them to voicemail.

To block one caller, open Phone, tap Contacts, pick the contact and choose Block Contact.

Filtering can send real calls to a list or to voicemail. Save important numbers as contacts, and check the Unknown Callers list, the Spam list and your voicemail now and then.

This matters most if you expect calls from work, a clinic or a delivery service.

Messages: screen unknown senders

Open Messages, use the menu in the conversation list, and tap Manage Filtering. Switch on Screen Unknown Senders. Apple notes you can keep notifications on for categories like verification codes.

Apple also provides Text Message Filter, which files messages from unknown senders under Transactions and Promotions. It stops applying once you have replied to a sender three or more times, so block or report those senders yourself.

AirDrop: choose who can send you things

In Control Center, press and hold the group of controls at the top left, tap AirDrop, then pick Contacts Only or Everyone for 10 Minutes. As the name says, the second choice is time-limited.

Apple's page says an AirDrop code is required from senders outside your contacts when the devices run version 26.2 or later of iOS, iPadOS or macOS. That depends on the software on the devices involved.

Once you agree, Apple says you can exchange items with that person for 30 days without a new code.

Wi-Fi: reduce tracking across networks

Open Settings, tap Wi-Fi, then tap the information button beside your network. There Apple lists Private Wi-Fi Address, which makes it harder to track your iPhone from one Wi-Fi network to the next.

It also lists Limit IP Address Tracking, which Apple says hides your IP address from known trackers.

That is a limited protection. It does not make your IP address invisible to every website, app or network. Both settings apply per network, so check the networks you use most, such as home and work.

Safari: lock your private tabs

Private Browsing opens tabs that are left out of your History and out of the tab list on your other devices. Apple says Private Browsing locks itself when you are not using it, provided your iPhone has a passcode.

To control that, go to Settings, tap Apps, then Safari, and turn on the option to require a passcode, Face ID or Touch ID to unlock Private Browsing. Which option you see depends on your model.

Check who else can see your information

Apple's Safety Check page explains how to manage information sharing with people and apps. It is worth a look if you have shared your location, photos or accounts with someone and the situation has changed.

It sits under Privacy & Security. Our ranked guide to iPhone privacy settings walks through it alongside Lockdown Mode and Stolen Device Protection.

Reset all settings if things go wrong

Go to Settings, then General, then Transfer or Reset iPhone, and tap Reset.

Apple says Reset All Settings returns settings to their defaults, covering network, keyboard dictionary, location, privacy and Apple Pay cards, while leaving your data and media in place.

Because it changes so much, use it for broader problems and not for a single app. Saved Wi-Fi networks and similar settings go back to their defaults too.

Apple also recommends a backup beforehand when you want to hold on to your current settings. Use this only if app permissions are badly tangled.

Frequently asked questions

What iPhone privacy settings should I turn off?

Start with app access you do not need under Privacy & Security, and Lock Screen features that show personal information. Our ranked guide covers tracking, location and advertising.

What iPhone privacy settings should I turn on?

Call filtering in Phone settings, Screen Unknown Senders in Messages, AirDrop set to Contacts Only, and Private Wi-Fi Address.

Why is an app asking for access again?

Apple says you can change access later, so check Settings, Privacy & Security for the app. Apps ask when a feature first needs a permission.

Will Reset All Settings erase my photos?

No. Apple says it removes no data or media, though it resets other settings, so a backup first is wise.

Where is the screen lock setting?

Settings, then Face ID & Passcode, or Touch ID & Passcode on models with a Home button.
