Your iPhone contains a wealth of personal information – from photos and messages to location data and browsing history. While Apple takes measures to protect user privacy, there are some default iPhone settings that could potentially expose your sensitive information if left unchanged.
In this comprehensive guide, we’ll walk through the key privacy settings you should review and adjust on your iPhone. Implementing these changes can help safeguard your personal data from hackers, advertisers, and other third parties trying to access it without your consent.

Login Security Settings
Let‘s start by securing how you log into your iPhone to prevent unauthorized access.
1. Create a Strong Passcode
Replace your simple 4-digit passcode with a longer, complex alphanumeric code. Go to Settings > Face ID & Passcode (or Touch ID & Passcode). Turn off Simple Passcode, then create a passcode with at least 6 characters, containing a mix of letters, numbers and symbols.
Complex passcodes are harder for cybercriminals to crack. Avoid repeating or sequential characters. Don‘t use personal information like birthdays either.
2. Set Up Biometric Authentication
Enable Face ID or Touch ID for quick, secure unlocking. Go to Settings > Face ID & Passcode > Set Up Face ID (or Touch ID & Passcode > Add Fingerprint). Follow the prompts to register your face or fingerprint.
With biometric authentication, only you can access your iPhone data. It‘s more convenient than inputting a passcode every time.
3. Enable Two-Factor Authentication
Turn on two-factor authentication (2FA) for an extra layer of account security. Go to Settings > [your name] > Password & Security > Turn on Two-Factor Authentication. Enter your phone number to receive verification codes when logging in.
With 2FA, accessing your accounts requires both your password and a temporally valid code from your phone. This prevents unauthorized logins even if your password is compromised.
4. Use "Sign In with Apple"
Use Sign in with Apple when available to securely log into apps and websites without revealing personal information. Look for the Sign in with Apple button and authenticate with Face ID, Touch ID or your passcode.
This feature creates randomized email addresses to share with logins to prevent companies from connecting your activity across sites.
5. Restrict Lock Screen Access
Limit lock screen previews. Go to Settings > Face ID & Passcode and disable Show When Locked for messages, notifications and other sensitive items. This prevents content from displaying when your phone is locked.
6. Review Notification Privacy Settings
Customize notification settings for privacy. Go to Settings > Notifications, then turn off Allow Notifications and Show Previews for specific apps. Disable Share My Activity to stop sharing Siri requests.
This prevents personal notifications from appearing on your lock screen. You can decide which apps can display content notifications.
iOS App Settings
Adjust settings within Apple‘s preinstalled apps for enhanced security.
7. Adjust Siri Settings
Restrict Siri‘s access when your phone is locked. Go to Settings > Siri & Search and toggle off Listen for "Hey Siri", Press Side Button for Siri and Allow Siri When Locked. Also disable Siri Suggestions & Privacy.
This prevents Siri from being activated without authentication and stops Siri from utilizing your app activity and data to provide suggestions.
8. Auto-Delete Old iMessages
Automatically delete older iMessages for privacy. Go to Settings > Messages > Keep Messages and select a duration like 30 days. Tap Delete to confirm.
Regularly deleting old iMessages reduces the amount of message data stored on your device and in iCloud backups.
9. Review iCloud Backup Permissions
Audit which apps can back up your data to iCloud. Go to Settings > [your name] > iCloud > Manage Storage > Backups. Disable backups for apps with sensitive information.
You can select which app data to exclude from iCloud backups. This prevents that data from being stored long term where it could be accessible to Apple or hackers.
10. Enable Find My iPhone
Remotely locate, lock or erase your iPhone if it‘s lost or stolen. Go to Settings > [your name] > Find My and turn on Find My iPhone. Also enable Send Last Location.
Activating these features lets you track your device location, prevent misuse if missing, and wipe data remotely.
Check who can share content with you in the Shared With You section. Go to Settings > Messages > Shared With You. Ensure only trusted contacts have access.
This prevents unknown people from sharing potentially malicious content directly into your messages.
Be selective about sharing your real-time location with others. In the Find My app, tap the People tab. Choose who to share with and when. Tap Stop Sharing to revoke access.
You can temporarily share location with family and friends as needed for meetups or emergencies, without granting open-ended access.
13. Enable Mail Privacy Protection
Mask your IP address to obscure your location and usage patterns. Go to Settings > Mail > Privacy Protection and turn on Protect Mail Activity.
This hides your network information from senders, providing an additional layer of email privacy.
14. Tweak Safari Settings
Safari has multiple privacy settings to control tracking and security. Go to Settings > Safari and review options like Prevent Cross-Site Tracking, Block All Cookies and Fraudulent Website Warning.
Adjust these based on your privacy priorities. More restrictive settings reduce tracking but can impact functionality.
15. Block Contacts
Block unwanted calls and messages from specific contacts. Open the Phone app, tap the “i” icon next to a contact and select Block Contact.
This sends calls directly to voicemail and prevents the contact from contacting you. Useful for stopping harassment or spam.
Third-Party App Settings
Apps from the App Store can collect and share your data. Here’s how to limit their access:
16. Review App Permissions
Check what information each app can access. Go to Settings > Privacy and select app categories like Location, Contacts, Photos. Toggle access off for apps as desired.
Being highly selective about app permissions prevents sensitive data collection without your knowledge or consent.
17. Enable App Privacy Report
Monitor how apps use your data over time. Go to Settings > Privacy > App Privacy Report and turn it on. Open it to see usage reports per app.
This transparency helps you identify any apps with suspicious levels of data access so you can better restrict their permissions.
18. Turn On App Tracking Transparency
Block apps from tracking your activity across other companies‘ apps and websites. Go to Settings > Privacy > Tracking and toggle on App Tracking Transparency.
This gives you more control over which apps can track you for ad targeting purposes.
19. Install App Updates
Keep apps fully updated for the latest privacy protections. Go to Settings > [your name] > iTunes & App Store. Turn on automatic updates or manually update apps regularly.
App developers release updates to address vulnerabilities and comply with new privacy regulations, so staying updated is critical.
Data Collection Settings
Here are a few other settings to limit iPhone data collection:
20. Disable Analytics Sharing
Stop sharing analytics data with Apple. Go to Settings > Privacy > Analytics & Improvements. Toggle off Share iPhone Analytics and Share iCloud Analytics.
This prevents Apple from accessing usage statistics and crash data from your device.
21. Review Location Services
Only allow location access when needed for specific apps. Go to Settings > Privacy > Location Services. Toggle it off for each app.
Selectively using location services maintains privacy without fully disabling the useful features requiring your location.
22. Limit Ad Tracking
Opt out of targeted ads for more privacy. Go to Settings > Privacy > Apple Advertising and toggle off Personalized Ads. For more control, install an ad blocking VPN.
Disabling ad tracking reduces commercial surveillance of your online activities for behavioral advertising purposes.
23. Disable Significant Locations
Turn off location history collection. Go to Settings > Privacy > Location Services > System Services. Toggle off Significant Locations.
This prevents Apple from storing detailed logs of locations you visit, which could reveal sensitive information about you.
Take Additional Measures for Privacy
While adjusting your iPhone settings is a great start, here are a few other things you can do for enhanced privacy:
-
Use a VPN to encrypt your web traffic and mask your IP address from trackers.
-
Clear your cookies, caches and histories in Safari regularly.
-
Be wary of public WiFi networks and consider using a VPN to keep your connection secure.
-
Set all social media accounts to the strictest privacy options.
-
Cover your phone camera when not in use to prevent unauthorized access.
-
Frequently change passwords, avoid password reuse, and use a password manager.
-
Carefully check the reputation of any new apps before downloading and granting permissions.
-
Update to the latest version of iOS for improved security protections.
-
Set up an antitheft solution in case your device is lost or stolen.
