iPhone Privacy Checklist: 15 Settings to Change in 2026
A comprehensive checklist of 15 iPhone privacy settings you should update right now, organized by category with step-by-step instructions.
Your iPhone Knows More Than You Think
Your iPhone is a remarkable device, but it collects an enormous amount of data about you. Your location history, browsing habits, app usage patterns, contact networks, and even the way you type are all tracked and stored to varying degrees. Some of this data collection improves your experience. Some of it exists primarily to serve advertisers.
Apple has built strong privacy tools into iOS, but many of them are opt-in or buried in settings menus. This checklist walks you through the 15 most impactful privacy changes you can make on your iPhone, organized by category.
You don't need to change everything — pick the items that matter most to you and start there.
Lock Screen Security
1. Require Attention for Face ID
By default, Face ID unlocks your iPhone even if you're not looking at it. This means someone could hold your phone in front of your face while you're sleeping or distracted and unlock it.
Go to Settings > Face ID & Passcode.
Enable Require Attention for Face ID.
Now Face ID only works when your eyes are open and looking at the camera.
2. Disable Lock Screen Notifications Preview
Notification previews on your lock screen expose message contents, email subjects, and other private information to anyone who can see your screen.
Go to Settings > Notifications > Show Previews.
Change the setting to When Unlocked (or Never for maximum privacy).
You'll still see which apps are sending notifications — just not the content until you authenticate.
3. Disable USB Accessories When Locked
Law enforcement tools like GrayKey can extract data from locked iPhones through the charging port. iOS has a setting to prevent this.
Go to Settings > Face ID & Passcode.
Make sure USB Accessories is toggled OFF under "Allow Access When Locked."
This blocks USB data connections when your iPhone has been locked for more than an hour.
Safari & Browsing Privacy
4. Block Cross-Site Tracking
Safari has built-in Intelligent Tracking Prevention, but you should verify it's enabled.
Go to Settings > Safari.
Under Privacy & Security, make sure Prevent Cross-Site Tracking is enabled.
This stops advertisers from following you across different websites.
5. Hide IP Address from Trackers
Your IP address can be used to identify your general location and link your activity across websites.
In Settings > Safari, under Privacy & Security.
Tap Hide IP Address and select From Trackers.
Safari will route tracker requests through a proxy, masking your real IP address from known trackers.
6. Enable Fraudulent Website Warning
Protect yourself from phishing sites that mimic legitimate websites.
In Settings > Safari, under Privacy & Security.
Enable Fraudulent Website Warning.
Safari will check websites against Google's Safe Browsing list and warn you before loading known fraudulent sites.
Location Privacy
7. Review App Location Permissions
Many apps request location access that they don't genuinely need. A weather app needs your general location, but a flashlight app certainly does not.
Go to Settings > Privacy & Security > Location Services.
Review each app and set it to Never, Ask Next Time, or While Using — avoid Always unless you have a specific reason.
Apps set to "Ask Next Time" will prompt you each time they request your location, giving you full control over when your location is shared.
8. Disable Frequent Locations
Your iPhone keeps a detailed log of places you visit frequently, including your home, workplace, and other regular destinations. This data is stored on your device and used for personalized services, but it represents a significant privacy footprint.
Go to Settings > Privacy & Security > Location Services > System Services.
Tap Significant Locations and toggle it OFF.
Tap Clear History to remove your existing location history.
App-Level Privacy
9. Limit Ad Tracking
Apple requires apps to ask for permission before tracking your activity across other companies' apps and websites, but you can block this entirely.
Go to Settings > Privacy & Security > Tracking.
Toggle Allow Apps to Request to Track to OFF.
This prevents all apps from even asking to track you. Apps that previously had permission are automatically revoked.
10. Review App Privacy Reports
iOS generates a privacy report showing how apps use your data.
Go to Settings > Privacy & Security > App Privacy Report.
Review which apps access your location, camera, microphone, contacts, and other sensitive data.
If an app accesses data unexpectedly, consider revoking its permissions or uninstalling it.
The App Privacy Report is one of the most underused features in iOS. Check it weekly — it reveals which apps are quietly accessing your camera, microphone, and location in the background.
11. Lock Sensitive Apps with Invis
Even with tight permissions, apps on your home screen are accessible to anyone who has your unlocked iPhone. Whether you hand your phone to a friend, a colleague, or a family member, they can open any app they see.
Invis lets you lock individual apps behind Face ID. This means even when your iPhone is unlocked, protected apps require a separate biometric authentication before they can be opened.
Use Invis to protect apps like:
Personal Apps
Photos, Messages, Health, Notes — anything with private content you don't want others browsing through.
Financial Apps
Banking, investment, and payment apps that could cause real damage if accessed by someone else.
Setting up Invis takes under two minutes: download the app, select which apps to protect, and enable Face ID locking. You can also group apps together, so activating "Work Mode" or "Privacy Mode" locks or hides multiple apps at once.
12. Disable Background App Refresh
Many apps refresh their content in the background, which means they're actively running — and potentially collecting data — even when you're not using them.
Go to Settings > General > Background App Refresh.
Set it to Off or Wi-Fi only, and individually disable background refresh for apps that don't need it.
This also improves your battery life significantly.
Data Protection
13. Enable Find My iPhone with Stolen Device Protection
If your iPhone is stolen, Find My iPhone lets you locate, lock, or erase it remotely. Stolen Device Protection adds a security delay for sensitive changes when your iPhone is away from familiar locations.
Go to Settings > [Your Name] > Find My and ensure Find My iPhone is enabled.
Go to Settings > Face ID & Passcode > Stolen Device Protection and enable it.
With Stolen Device Protection enabled, changing your Apple ID password, turning off Find My, or erasing your device requires Face ID and has a one-hour security delay when you're away from familiar locations like home or work. Make sure Face ID is reliable before enabling this feature.
14. Limit Access to Shared Albums and Devices
If you use iCloud Shared Albums, Family Sharing, or have multiple Apple devices, your photos and data may be more exposed than you realize.
Go to Settings > [Your Name] > iCloud and review which apps sync to iCloud.
In Settings > Photos, disable Shared Albums if you don't use them.
Review Settings > [Your Name] > Family Sharing to see what's being shared with family members.
15. Encrypt Your iPhone Backup
If you back up your iPhone to a computer, those backups contain your complete device data. Without encryption, this data is stored in a readable format.
Connect your iPhone to your computer and open Finder (Mac) or iTunes (Windows).
Select your iPhone and check Encrypt local backup.
Choose a strong password that you'll remember — there's no way to recover an encrypted backup password.
iCloud backups are automatically encrypted by Apple. This step is specifically for people who back up to a local computer.

Privacy isn't a one-time setup — it's an ongoing practice. Bookmark this checklist and revisit it every few months. iOS updates often introduce new privacy features and change default settings.
You don't need to change all 15 settings today. Start with the high-impact items in each category: lock screen security, Safari tracking, location permissions, ad tracking, and app-level protection with Invis. Each change takes less than a minute and meaningfully reduces how much data is accessible about you.
