We track fraudsters across cookies.

Yes, really.

Nice to meet you, stranger.

We don't see a cookie from you. Either we’ve never met or you deleted it. To most websites, you'd look brand new.

Why does that matter?

Most sites recognize returning visitors using a browser cookie. Malicious users clear it to cover their tracks. That's how one person claims the same signup bonus a hundred times, farms referral payouts, or comes back the day after a ban.

Our ID sticks around even when cookies don't.

What happens when I click?

Every browser reveals information like your fonts, language, and browser version. We collect hundreds of these signals to match a session to the exact device it came from, all in less than a second. If we don’t have enough information for a definite match, you get a fresh ID instead.

Your name is used to label the sessions so you can spot them in the list. We do not use it for matching.

Any website can recognize you by cookie. It’s also the first thing a fraudster deletes.

Wipe it and see if we still know it’s you.

What does the wipe remove?

Everything this page stored in your browser, cookie included. The next check has to recognize the device cold. We do not read or delete your other site data.

How did you find me without a cookie?

Every browser reveals information like your fonts, language, and browser version. We collect hundreds of these signals to match a session to the exact device it came from, all in less than a second. If we don’t have enough information for a definite match, you get a fresh ID instead.

This device looks new to us.

We didn’t find any devices that looked like yours. We only link sessions when we’re sure, since a wrong ID could turn a real customer into a fraud suspect.

Expected a match?

Some browsers intentionally scramble their information, making it harder for us to match with confidence. We catch these users with other parts of our stack.

That wipe got past us.

Nothing we saw matched with enough confidence. We only link sessions when we’re sure, since a wrong ID could turn a real customer into a fraud suspect.

Seeing this a lot?

Some browsers intentionally scramble their information, making it harder for us to match with confidence. We catch these users with other parts of our stack.
