Review these nine controls in Settings > Privacy & Security to limit unnecessary app access and see what is being shared. They are not nine switches everyone should enable blindly: keep the access a feature genuinely needs, and choose the narrowest level that still works. Menu labels can vary by iOS version and region.
1. Stop apps from requesting cross-company tracking
Go to Settings > Privacy & Security > Tracking. Turn off Allow Apps to Request to Track to prevent apps from asking for this permission, or leave requests enabled and deny them individually. You can change your choices later. This setting governs permission to track you across other companies’ apps and websites; it does not stop every kind of data collection. Apple explains how tracking permission works.

2. Review location access for every app
Open Settings > Privacy & Security > Location Services and inspect the apps listed. For each one, choose an access level that fits its purpose, and avoid background or always-on access when the app does not need it. Turning Location Services off can limit location-dependent features on the iPhone as well as in apps. Apple’s location settings guide describes the available controls.

From Location Services, tap an app and switch off Precise Location if a general area is sufficient for what you use it for, such as broad local recommendations. Apps for turn-by-turn navigation or arranging a pickup may need a more exact location. Make this choice app by app rather than treating precision as universally unnecessary.

4. Remove camera access apps do not need
In Settings > Privacy & Security > Camera, review the apps with permission and revoke access where the app’s intended function does not require it. iPhone displays an indicator when the camera is in use; Apple identifies the camera-use indicator as green. For details on permission prompts and indicators, see Apple’s guide to controlling access to hardware features.
5. Limit microphone access
Go to Settings > Privacy & Security > Microphone and keep permission for apps that need it for features you use, such as calls or recording. Revoke it for apps without a clear microphone-related purpose. Apps must ask before using the camera or microphone, and you can revisit your choices in Settings.

6. Check access to photos and other sensitive information
Under Settings > Privacy & Security, review categories such as Photos, Contacts, Calendars, Reminders, Bluetooth, Local Network and Health. The lists show apps that have requested access; an app that is not listed has not necessarily been granted access. Adjust or revoke each app’s permission according to the data and feature involved. Apple’s privacy controls guide covers these categories.
7. Turn on App Privacy Report
Go to Settings > Privacy & Security > App Privacy Report and turn it on. The report can show how often apps accessed sensitive data and sensors, as well as app and website network activity. Its Data & Sensor Access view covers the past seven days, but it starts collecting only after you activate it. Use your iPhone normally for a while before drawing conclusions from the report. Apple says report data is encrypted and stored on your device; turning the report off clears that data. See About App Privacy Report.

8. Review what you share with people and apps
Open Settings > Privacy & Security > Safety Check, then choose Manage Sharing & Access to review supported sharing. Depending on your setup, this can include shared location or content, app permissions, connected devices and account-security information. Some options may not be available if Screen Time restrictions or mobile device management controls apply. Apple describes Safety Check for iPhones running iOS 16 or later.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.9. Know where Emergency Reset is—and when to use it
Emergency Reset is also in Safety Check. It can quickly stop supported sharing and reset access, so it is intended for urgent circumstances, not routine privacy maintenance. It does not cover every possible channel: Apple notes that some accounts and passwords, social-media sharing, or sharing from another device may require separate action. If you use it, follow the on-screen steps and review anything outside Safety Check separately.
