Control Analytics Data Shared With Apple
Analytics & Improvements controls whether your iPhone automatically sends anonymized crash reports and usage analytics to Apple, and optionally to third-party app developers, to help diagnose problems and improve software.
How to open Analytics & Improvements
- Open Settings → Privacy & Security → Analytics & Improvements.
- Toggle Share iPhone Analytics and Share iCloud Analytics as desired.
- Toggle Share With App Developers if you're comfortable sharing analytics with third-party developers.
- Tap Analytics Data to browse the actual log files stored on the device.
What you should know
- Share iPhone Analytics sends device and app crash logs to Apple for diagnostic purposes.
- Share iCloud Analytics sends usage data specifically about iCloud features.
- Share With App Developers lets analytics data be shared with the developers of apps you use, when enabled.
- Analytics Data lets you view the actual raw crash and diagnostic logs stored on the device.
Apple states this analytics data is designed to be anonymized before it's sent, but turning it off entirely is a valid choice if you'd rather not share any usage data.
Why it matters
This data is genuinely one of the tools Apple and developers use to catch app crashes and performance regressions that don't show up in testing, so leaving it on can indirectly improve software quality over time. On the flip side, it's also a legitimate privacy lever for anyone who prefers to minimize what leaves their device, even in anonymized form.
Best practices
- Leave analytics sharing on if you don't mind contributing anonymized data and want Apple to catch bugs faster.
- Turn off 'Share With App Developers' specifically if you're fine sharing with Apple but not third-party developers.
- Check Analytics Data yourself after a crash if you're trying to troubleshoot a specific misbehaving app.
Common problems and fixes
- Analytics toggles appear greyed out or unchangeable
- This can happen under certain Screen Time or MDM (mobile device management) restrictions — check Screen Time → Content & Privacy Restrictions or contact whoever manages the device profile.
- Analytics Data list is empty despite recent app crashes
- Logs can take a little time to generate after a crash — reopen the crashed app once more, then check Analytics Data again after a few minutes.
Tips and tricks
- A crash log's filename and timestamp under Analytics Data can help pinpoint exactly which app crash you're troubleshooting.
Frequently asked questions
Does turning off analytics sharing affect iPhone performance?
No, it only affects what diagnostic data leaves your device — it has no effect on how the iPhone itself performs.
Can I see exactly what data is being shared with Apple?
Yes, tapping into Analytics Data lets you open and read the actual log files that would be shared, in plain text form.

- Diagnostic LogEvery app crash or system hang on iPhone generates a diagnostic log you can view directly on the device, useful for troubleshooting a misbehaving app yourself or sharing details with a developer or support team.
- Location ServicesLocation Services is the master switch and per-app control center for GPS-based location sharing on iPhone, letting you decide exactly which apps can see your precise or general location, and when.

- Reset iPhoneReset options let you fix persistent software issues by resetting specific settings (like network or keyboard dictionary) or fully erase the device back to factory defaults.
- Recovery Mode & RestoreRecovery Mode is a special startup state used with a computer running Finder (or iTunes on older systems) to reinstall or restore iOS when an iPhone is frozen, stuck on the Apple logo, or won't update normally.
- Battery Health & ChargingBattery Health & Charging shows your battery's Maximum Capacity as a percentage of its original capacity, its Peak Performance Capability status, and charging optimization options — the key diagnostic info for battery-related complaints.
- Force Restart & Shut DownA force restart or full shut down can resolve a frozen or unresponsive iPhone using a physical button sequence, without needing to reach Settings at all.
- Erase All Content and SettingsErase All Content and Settings permanently deletes everything on the iPhone, including apps, photos, settings, and accounts, restoring it to an out-of-box state, distinct from resetting individual settings categories.
- DFU Mode RestoreDevice Firmware Update (DFU) Mode is the lowest-level restore state available on iPhone, used when the device won't respond to a force restart or standard Recovery Mode, typically requiring a computer with Finder or iTunes.
