You should probably have the "Improve Siri & Dictation" setting off — here's why

Your iPhone, iPad or Mac will ask you to enable the Improve Siri & Dictation toggle when you set it up. If you skip Siri during setup, you'll have to decide this the first time you use translation, dictation, or Siri features. For an Apple Watch or HomePod speaker, the setting will mirror what you have on your iPhone or iPad by default. It's similar for an Apple TV if you walk through setup using your iPhone or iPad, though manual opt-in is also an option.

To change this setting on your iPhone or iPad later, open Settings and enter the Privacy & Security section. There, scroll down and tap Analytics & Improvements. Disable the Improve Siri & Dictation slider, along with any other types of information you don't want to share. If you wish, you can also delete the local voice data from your device by going to Settings > Apple Intelligence & Siri > Siri & Dictation History > Delete Siri & Dictation history.

On a Mac, click the Apple menu and choose System Settings. In the sidebar, select the Privacy & Security tab. Then choose Analytics & Improvements to disable Improve Siri & Dictation.

For your Apple Watch, open the Settings app, then visit General > Analytics & Improvements to find the Improve Siri & Dictation slider.

If you own a HomePod, you can adjust this setting in the HomePod app on your iPhone or iPad. After opening the app, touch and hold your HomePod icon, then tap Accessory Settings. From there, tap Analytics & Improvements, then adjust the Improve Siri & Dictation setting accordingly.

Apple TV owners should navigate to the Settings app, then select General > Privacy > Analytics & Improvements to find Improve Siri & Dictation.

If you happen to own an Apple Vison Pro, open the Settings app on the device, choose Privacy & Security, select Analytics & Improvements and deselect Improve Siri & Dictation.
