4. Delete Gemini History
If you've used Gemini before, your chats may be saved, and some could be reviewed by humans.
Go to http://myactivity.google.com/product/gemini → Turn off Gemini Apps Activity → Delete Activity → All Time.
This removes your past Gemini chat history and stops future conversations from being saved.
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.

My husband and I use tuta (@Tutanota) for sending encrypted email. The account also includes a calendar.
I started with a free account just to test it out and then moved to the paid tier to get some more features.
