5. Move Sensitive Emails
Turning off Gmail's smart features helps, but for truly private emails, consider using a separate service.
For medical, legal, or financial emails, use a free Proton Mail account. It offers end-to-end encryption and doesn't use AI to scan your emails.
Keep Gmail for newsletters, promotions, and less sensitive messages.
4. Delete Gemini History
If you've used Gemini before, your chats may be saved, and some could be reviewed by humans.
Go to https://t.co/hFkX9Gyisw → Turn off Gemini Apps Activity → Delete Activity → All Time.
This removes your past Gemini chat history and stops future conversations from being saved.
3. Your Phone
The settings don't always sync between devices, so check the Gmail app separately.
Gmail app → Menu (☰) → Settings → Select your account → Turn off "Smart features and personalization" → Confirm.
2. The Hidden Switch
Turning off the first setting isn't enough. Most people stop there.
On the same settings page: Google Workspace smart features → Manage Workspace smart feature settings → Turn off both checkboxes → Save.
Both settings need to be turned off.
1. The Main Switch
This is the main setting Google shows you, but it's not the only one.
Gmail (Desktop):
⚙️ Settings → See all settings → Smart features and personalization → Uncheck "Turn on smart features in Gmail, Chat, and Meet" → Save Changes.
