Free, no account
Check if my email has been in a data breach
Enter an email address and see which publicly known breaches it appears in, what each one exposed, and the steps to take next. It is free and needs no account.
The address you check is never stored in full. We keep only a masked version and a one-way hash.
What the check searches, and what a result means
The check covers publicly known breaches, not every breach that has ever happened.
The check looks through publicly known data breaches. These are the ones that have been reported and published. We do not search, buy or hold stolen data, and we never scan hidden corners of the internet.
If your email is found, you see each breach it appears in and the kind of data that leaked, such as passwords, phone numbers or dates of birth. Each result links to plain steps for that breach, so you know what to change first.
An empty result is good news, but it is not proof you were never exposed. It only means your address was not in the breaches we can see. New breaches come to light all the time, and some are never made public.
What you see when you check your email for breaches
There are three outcomes, and each one tells you something different.
A breach was found
You see each publicly known breach your address appears in, what it exposed, and a short plan for that breach. Start with the fix that matters most, usually your email account password.
An empty result
We did not find your address in the breaches we can see. Treat it as reassuring, not final, because not every breach is made public and new ones appear often.
A phone number
A phone number gets guidance, not a breach lookup. We show how to lower SIM-swap risk and how to remove the number from people-search sites.
What each breach exposed
Every result names the data types involved, so you can see whether a password, an address or a date of birth was part of the leak.
How the check works, step by step
Four steps, and your address is never stored in full.
You enter an email address
Type the address you want to check. We never ask for your password, and you do not need an account to run the check.
We mask and hash it
We create a masked version that hides most of the characters, and a one-way hash, which is a scrambled fingerprint that cannot be turned back into your address. The full address is never kept.
We match publicly known breaches
We compare against publicly known breaches and return the ones your address appears in, along with the data each one exposed.
You get results and clear steps
Each breach links to plain, ordered steps. For the full recovery plan, read what to do after a data breach.
