5. Move Sensitive Emails

Unless you turn them off, the AI can still analyze your inbox to provide these features.

If you have a Gmail account, you need to read this.
Google's AI now scans your emails and attachments, bank statements, tax files, medical letters, all of it. It turned on by default, and there's a class-action lawsuit over how.
Here are 5 moves to shut it off, the switch is hidden in two places:
