Gemini · AI agent leak test

Does Gemini share your email with websites? Test it.

Gemini fetches web pages through Google's systems, so a leak is less likely. Check what happens when a site demands a contact email.

Free, no sign-up, about 60 seconds. Results are private and deleted after 1 hour.

Lower risk: Gemini normally fetches pages through its provider's servers with fixed headers, so a header leak is less likely.

Does Gemini make its own network requests?

In normal chat, Gemini uses Google’s systems to search and read web pages. Google doesn’t publish a separate user agent for these chat fetches. The model usually can’t choose custom headers, which makes this a lower-risk setup for a User-Agent leak.

Google also runs agents that act on the web for you; Google documents a Google-Agent user agent for agents hosted on its infrastructure that browse and act on user request. If you use them, test them too: they may be able to fill in forms or details for you.

FAQ

Can Gemini send my email to a website?

In normal chat, web pages are fetched by Google's systems, and the model usually can't set custom headers. A leak through headers is unlikely, but the model could still add information to a URL.

No request arrived. Why?

Gemini may have answered from search results without opening the link. Ask it to open the exact URL.
