Turn off Allow Apps to Request to Track at Settings > Privacy & Security > Tracking. This stops apps from prompting you for permission; Apple says apps that request tracking while the switch is off are treated as if you chose Ask App Not to Track.
How to turn off app tracking requests
- Open Settings.
- Tap Privacy & Security, then Tracking.
- Turn off Allow Apps to Request to Track at the top of the screen.
Apple says this setting suppresses tracking permission prompts. You can also review apps that have previously requested permission on the Tracking screen and change an individual app’s choice later. Apple’s instructions for tracking requests explain the available choices.
What the setting blocks—and what it does not
Apple defines tracking here as linking information that identifies you or your device, collected in an app, with similar identifying information from apps, websites, or other places owned by other companies. The purposes include targeted advertising, ad measurement, and sharing collected information with data brokers.

When you deny a request, Apple says the app cannot access the system advertising identifier (IDFA) and is not allowed to track you using other identifying information, such as an email address. Apple also says you can still use the app’s full capabilities after denying tracking.

This is not a universal off switch for data collection or every form of tracking on the web. It applies to the cross-company tracking covered by Apple’s permission system; it does not mean an app stops collecting information for its own purposes.
App Tracking Transparency and Safari privacy are separate
The Tracking switch controls app permission requests. Safari has a separate control for browsing: Prevent Cross-Site Tracking, which Apple says limits third-party cookies and data by default. Apple’s iPhone guide also describes Safari’s Privacy Report, which shows trackers encountered and prevented by Intelligent Tracking Prevention. These Safari tools do not change an app’s tracking permission.

Why the Tracking switch may be unavailable
Apple says the option may be unavailable in certain circumstances:
- You use a child account or an account for someone under 18 by birth year; the age threshold for child accounts varies by country or region.
- Your Apple Account is managed by an institution, or your device has a configuration profile that limits tracking.
- Your Apple Account was created within the previous three days.
These restrictions are about eligibility for the control, not evidence that the device is malfunctioning.
