Stop Sharing Analytics on iPhone in iOS 26

Turn off Share iPhone Analytics to stop sending diagnostic and usage data from your iPhone to Apple. The setting is available in the Privacy & Security menu; you can change it on the device without deleting apps or resetting your iPhone.

What You’ll Need

An iPhone running iOS 26. Menu wording can vary slightly if your device is on a different iOS version.
Your iPhone passcode, if the device asks you to authenticate before changing a setting.

Step-by-Step

Open Settings. Find the gray gear icon on your Home Screen or in the App Library. You do not need to connect to Wi-Fi or sign in again to change this preference.
Open Privacy & Security. Scroll down the main Settings list and tap Privacy & Security. If you cannot see it, use the search field at the top of Settings and enter “Privacy & Security.”
Go to Analytics & Improvements. Scroll within Privacy & Security and tap Analytics & Improvements. This page contains Apple’s device analytics and related sharing options.
Turn off Share iPhone Analytics. Tap the switch next to Share iPhone Analytics so it is off. An off switch appears gray; check the switch itself rather than relying only on color if you use a different display appearance.
Review other sharing switches. The page may show separate options for sharing analytics from iCloud, Siri, or other features. Turn off any individual options you do not want to share. These are separate preferences; disabling the main iPhone analytics switch does not necessarily turn off every other analytics-related option.
Leave Settings and verify. The change normally takes effect without a restart. Return to Settings > Privacy & Security > Analytics & Improvements to confirm the main switch remains off. If you also changed another switch, verify that one separately.

Common Mistakes

Looking in the wrong menu. Analytics controls are under Privacy & Security, not the general Privacy settings of older guides or the Apple Account screen.
Assuming one switch controls everything. The page can have several independent sharing controls. Check each option whose data sharing you want to stop.
Confusing analytics with app permissions. This setting is not the same as Location Services, microphone access, or an app’s own privacy settings. Changing it will not revoke those permissions.
Expecting it to erase existing data. Turning off sharing changes future participation; it is not a request to delete diagnostic records Apple may already have received.
Following instructions for a different device. iPad and Mac have similar but not identical labels and paths. These steps are for an iPhone.

Tips

Use Settings search. Search for “Analytics” if the menu is hard to find. Open the result that leads to Analytics & Improvements and confirm the full path before changing a switch.
Read the descriptions on the page. Apple may show distinct controls for different services. The short explanatory text helps you decide which ones match your preference.
Check after a major update if you are unsure. A software update can change labels or layout. Revisit the page to confirm your choices rather than assuming the screen looks exactly like a guide.
Keep expectations realistic. Disabling analytics is a privacy preference, not a way to stop all data processing needed to provide Apple services or data collected independently by apps and websites.
Consider app-level choices separately. If your concern is data sent by a particular app, review that app’s privacy settings and its permissions in Settings. The iPhone analytics switch does not govern every app’s collection practices.

Troubleshooting

You cannot find Analytics & Improvements: Confirm you are in Settings > Privacy & Security, then scroll down. You can also search Settings for “Analytics.” If the result is missing, check that the phone has finished starting after an update and that you are using the iPhone’s Settings app rather than an app’s own settings.

The switch is unavailable or changes back: If the iPhone is managed by an employer, school, or another organization, a management profile may restrict some settings. Check Settings > General > VPN & Device Management for a profile, if that menu is present. Do not remove a work or school profile without asking its administrator; it can control access and device configuration.

You are using a child or family-managed device: Screen Time or organizational controls may limit access to settings. Ask the parent, guardian, or administrator who manages the device to review the restrictions. Do not try to bypass those controls.

The page looks different: Labels and available options can vary with iOS version, region, device configuration, or Apple services. Install available iOS updates if appropriate, then look for the analytics controls under Privacy & Security. If a specific option is absent, it may not be available on that configuration.

You want to remove data already shared: Switching off sharing does not itself delete data previously sent. Review Apple’s current privacy information or use the relevant privacy request options available for your account and region if you want to ask about data already associated with your account.

Frequently Asked Questions

Does turning off Share iPhone Analytics affect how my iPhone works?
It is intended to control sharing of diagnostic and usage analytics, not ordinary iPhone functions. It does not uninstall features or apps.

Does this stop every kind of data collection?
No. It controls the analytics sharing covered by that switch. Other Apple services, apps, websites, and permissions may involve separate data practices and settings.

Will it delete analytics Apple already received?
No. Turning the switch off is not an erase command for information previously shared. Check Apple’s privacy resources for applicable data access or deletion options.

Do I need to restart my iPhone?
Usually not. The preference should save when you turn off the switch. Reopen the page to verify it if you are uncertain.

Why do I see other analytics switches?
They apply to separate services or data categories. Review the description beside each one and turn off any additional sharing you do not want.

Can I turn analytics sharing back on later?
Yes. Return to Settings > Privacy & Security > Analytics & Improvements and turn on the relevant switch if you change your mind.

General steps for current mainstream versions; menus can differ by device and version. See the disclaimer or report an error.
