We specialise in securing your data, with access to over 8 billion public records we will help you find the information available to online criminals and hackers to avoid financial loss.
A small team of researchers and developers based in London. LeakPeek was founded on a common goal to bring cyber security closer to the public to ensure more steps are taken to secure our online data.
What we hold about you, and for how long, is set out in our Privacy Policy.
LeakPeek is a search interface. When you search for an email address, username or other detail, your query is sent to independent data providers and their answer is shown to you in real time. We don't hold a copy of the data ourselves. The point is to show you what is already out there about you, so you can change passwords, close old accounts and keep your information out of the wrong hands.
Searching for your own details, or details you are responsible for, is what the service is built for. We don't hold breach data ourselves: each search is answered in real time by independent data providers, and what comes back is shown to you. The Terms of Service set out how the service may and may not be used.
We operate within the laws that apply to us. What you may do with a search result is governed by the law where you are, so treat this page as general guidance and take legal advice in your own country if you are unsure.
As of September 2026, we have not been issued any government requests for information or secret court orders and are not currently under any gag orders.
