Most days you won't see anything. The note only appears when something genuinely looks wrong.
If an email ever feels off, just close it and walk away. You can always come back to it later.
It's already running. You'll never need to open it, update it, or think about it.
Only the email you have open on your screen, and only for a moment. It looks at the sender's address, the subject, and the words in the email — the same things you can see — to check whether anything looks like a known scam pattern. It doesn't store your emails or remember them after you close them.
No. Everything happens on your own computer, in your browser. Nothing about your emails leaves your device — not to us, not to anyone. There is no account, no sign-in, and no cloud.
It looks for patterns scammers use over and over: pretending to be a real company while sending from a strange address, links hidden behind shorteners, urgent threats meant to rush you, requests for passwords or card numbers. When enough of these add up in a single email, it speaks up. Real emails almost never have these patterns stacked together.
No. It only runs while Gmail is open in your browser, and the checks are very small — the kind of thing your computer does thousands of times a second without noticing. You can also turn it off any time from your browser's extensions menu.
