How to Protect Your Privacy When Using Dictation on Mac

Dictation on Mac is a convenient way to turn your speech into text, but it can also send your audio to Apple’s servers for processing. If you’re concerned about your privacy, this guide shows you how to keep dictation as private as possible, including using on-device processing, managing your dictation history, and disabling the feature when needed.

What You’ll Need

• A Mac running macOS Ventura or later (for on-device dictation support)
• An Apple ID (for syncing dictation settings across devices)
• Administrator access to change system settings (optional but helpful)

Step-by-Step

1. Open System Settings. Click the Apple menu in the top-left corner of your screen and select System Settings (or System Preferences on older macOS versions).
2. Go to Keyboard settings. In the sidebar, click Keyboard. Then, scroll down and click Dictation.
3. Enable On-Device Dictation (if available). Look for a toggle labeled Use On-Device Dictation. Turn it on. This keeps your audio on your Mac and doesn’t send it to Apple’s servers. Note: This option is available on Macs with Apple Silicon or Intel with the T2 chip, and only for certain languages. If you don’t see it, your Mac or language doesn’t support it.
4. Disable Dictation History (for older macOS). On macOS Monterey or earlier, open System Preferences > Keyboard > Dictation. Click About Dictation and Privacy and then click Delete Dictation History. This removes any previously stored audio recordings from Apple’s servers.
5. Turn Off Siri & Dictation History on macOS Ventura or later. In the same Dictation pane, click About Dictation and Privacy. If you see a button labeled Delete Dictation History, click it to remove any stored recordings. This is separate from on-device dictation, which doesn’t store audio.
6. Disable Dictation Entirely (if you don’t need it). If you rarely use dictation, turn off the Dictation toggle at the top of the Dictation pane. This ensures no audio is ever captured.
7. Use a VPN (optional, for extra privacy). While dictation audio is encrypted in transit, using a VPN adds another layer of privacy by masking your IP address. This doesn’t affect how Apple processes your audio, but it can help prevent network-level snooping.
8. Review Apple’s Privacy Policy. For full transparency, visit Apple’s Privacy page to understand what data is collected and how it’s used. This helps you make an informed decision about which settings to keep enabled.

Common Mistakes

• Assuming on-device dictation is always available. On-device dictation is only supported on certain Macs and for specific languages. If your language isn’t supported, your audio will still go to Apple’s servers even if you enable the toggle.
• Forgetting to delete dictation history. Even if you enable on-device dictation, any previous dictation sessions may still be stored on Apple’s servers. Always check and delete your history.
• Leaving dictation enabled when you don’t use it. If you never use dictation, keeping it enabled means your Mac is always listening for the shortcut key. Turning it off is the safest option.
• Not checking the language settings. Some languages default to server-based dictation. If you switch languages, re-check the on-device toggle.

Tips

• Use a dedicated shortcut for dictation. By default, dictation is triggered by pressing the Fn key twice. You can change this in the Dictation settings to a less accidental shortcut, like pressing Fn three times.
• Keep your Mac updated. Apple periodically improves on-device dictation and adds support for more languages. Updating macOS ensures you have the latest privacy features.
• Use offline dictation for sensitive info. If you’re dictating passwords, credit card numbers, or other sensitive data, make sure on-device dictation is on, or better yet, type that information manually.
• Check per-app permissions. Some apps may request microphone access for dictation. Review your privacy settings in System Settings > Privacy & Security > Microphone to see which apps have access.

Troubleshooting

On-device dictation toggle is grayed out. This means your Mac doesn’t support on-device dictation for the selected language. Try switching to a supported language (like English) or use an older macOS version where the option is available. Alternatively, accept that your audio will be sent to Apple’s servers and rely on other privacy measures.

Dictation doesn’t work after turning off history. Deleting your dictation history doesn’t disable the feature. If dictation stops working, ensure the Dictation toggle is still on and that your microphone is working. Restart your Mac if needed.

You can’t find the Delete Dictation History button. On newer macOS versions, the button may be under About Dictation and Privacy. If it’s missing, you may not have any stored history, or Apple has changed the location. Check Apple’s support page for the latest instructions.

Dictation is sending audio even with on-device enabled. Some dictation features, like punctuation or emoji suggestions, may still require server processing. To minimize this, use simple dictation and avoid using advanced features that rely on online processing.

Frequently Asked Questions

Does on-device dictation work offline? Yes, once you enable on-device dictation, your Mac can process your speech without an internet connection. However, the initial download of the dictation model may require internet.

Can I use dictation without sending audio to Apple? Yes, by enabling on-device dictation on a compatible Mac. If your Mac doesn’t support it, you cannot fully avoid sending audio to Apple.

How do I know if my Mac supports on-device dictation? Check the Dictation settings in System Settings. If you see the “Use On-Device Dictation” toggle, it’s supported. Apple’s support page also lists compatible Macs.

Does Apple store my dictation audio? If you use server-based dictation, Apple may store audio recordings for a limited time to improve Siri and dictation. You can delete this history manually, but it may not guarantee immediate removal from all backups.

Is dictation on Mac encrypted? Yes, audio sent to Apple is encrypted in transit. This prevents third parties from intercepting it, but Apple can still access the data.

Can I use third-party dictation apps that are more private? Yes, there are third-party dictation apps that offer on-device processing or end-to-end encryption. However, they may not be as accurate as Apple’s built-in dictation. Always research the app’s privacy policy before use.
