Getting Started

From zero to your first result in about a minute. Create an account, run a search, and learn how to read what comes back.

1 · Create an account

Head to sign up and register with an email and a password. Pick something strong and unique — your account is the only thing standing between your search history and someone else. Once you're in, you land on the dashboard.

We store the bare minimum: your email, a bcrypt-hashed password and rate-limiting counters. We never sell your queries. See the Privacy Policy for the details.

2 · Run your first search

Open Searches → Breach Data from the sidebar. The form is organised into tabs — Identity, Contact, Address and so on. You don't need to fill everything: a single field is enough to get started.

Drop an email into the Email field and hit Search. Filling more than one field narrows the results — every field you add is combined with AND, so the more you give, the tighter the match.

Use leak.fun to check your own exposure, or for legitimate security research. Looking people up to harass, dox or defraud them is against the Terms of Service and the law.

3 · Read the results

Each match is a card. A few things worth knowing:

  • Sensitive fields are hidden. Passwords and hashes sit behind a click-to-reveal, so a shoulder-surfer doesn't catch them by accident.
  • CONT shows linked records. When a leak ships related people (a parent, a co-account), the CONT control expands them inline.
  • Copy & download. Copy a single field, a whole record, or export the result set from the actions on each card.
  • Facets refine without re-querying. The panel on the right tallies cities, countries and sources from the current results — toggle a bucket to narrow the list instantly.

4 · Refine your query

Got too many results, or none at all? Every field has a CONT menu that controls how it matches — exact, starts-with, wildcards, fuzzy matching and more. That's the difference between a guess and a precise lookup.

The full list lives in Search Operators.

5 · Beyond breach data

The same dashboard gives you dedicated lookups for Discord, FiveM and Medal. Discord uses a small query language (the in-app builder writes it for you); the others take a single identifier and cross-reference every column.
