Cyduck is a personal cyber observatory. One score, drawn from the accounts you trust most — email, phone, social — and the breaches, leaks and exposures attached to each. Quiet, in your browser, no chase.
Not a sales pitch. Not a teaser. The same lookup the Scorer runs when you join — only this one is free, anonymous, and forgets your address the moment it answers. Most addresses appear in three breaches or more. Here's yours.
— Cyduck never stores or logs the email you type here. Decrypt runs as a single anonymous HIBP query.
Every account you connect — email, phone number, social login — is matched against breach databases, scored for posture, and rolled into a single figure. Not a lecture. Not a dashboard for the sake of it. A weather report, for your digital self.
A small kit of browser-only tools. Nothing leaves your device. No accounts. The same instruments the Scorer uses behind the scenes — yours to try in the open.
Find out which breaches your address appears in. The list is rarely empty.

Open the checkerA small arcade in the works. Hunt phishers, dodge trackers, defend the duck. Until then, try the test — a few short scenarios that ask how you'd react in the moment that matters.
Play the test →Most people don't think about cybersecurity. Until something breaks.
A hacked account. A leaked email. A message that looked harmless.
Cyduck exists for the moment before it happens. Not to scare you. Just to give you a small edge.
Everything here is built to be simple, fast, and private. No noise. No tracking. No nonsense.
If it helped you — even a little — that's enough.
No filler. The questions people actually send us, in the words we use to answer them.
