Find every known data breach that includes your email address, see exactly what was taken, and get a plan in the right order.
Your address is looked up and stored only as a one way hash plus a masked copy. It is never sold or added to a mailing list.
When a company is breached, the stolen records usually include email addresses. Those lists get copied, sold and merged into bigger collections that circulate for years. Your address being in one does not mean someone is inside your account right now. It means your address, and whatever else that company held about you, is sitting in a dataset criminals use.
This check searches the publicly known breach datasets for your address and shows you every hit. Instead of a bare count, you get the date of each breach, how big it was, exactly which types of data were exposed, an exposure score that weighs how dangerous that combination is, and an action plan ordered by what matters most for your result.
The most common harm from a breach is not the breached company being attacked again. Criminals take the email and password pairs and try them automatically against email providers, banks, shopping sites and streaming services. Anyone who reused that password is exposed on every site that shares it. That is why the plan puts password changes, starting with your email account, at the top.
Breach data also makes scams convincing. A message that knows your name, the company you used and roughly when you signed up reads as genuine. Phishing campaigns increasingly quote real breach details, and callers pretending to be your bank may recite your address or date of birth to seem legitimate.
Some data does not expire. A password can be changed in a minute, but a date of birth, a home address or a government ID number stays true. When those appear in your results, the goal shifts from undoing the leak to making the data less useful: freezing credit so accounts cannot be opened in your name, and removing yourself from the people search sites that combine breach data into public profiles.
Checking again matters. New breaches are added every week. Rechecking after a large breach is in the news, or every few months, tells you whether a new dataset has added to your exposure.
Enter the address above. If it appears in known breach datasets you will see each breach, what it exposed and when. Signs your actual account has been accessed are different: password reset emails you did not request, sign in alerts from unfamiliar places, sent messages you did not write, or new forwarding rules in your settings.
Your email address is not a secret, since you give it to every site you use, so checking it carries little risk. What matters is how the checker treats it. We do not sell or share it, we do not add it to a mailing list, and we store only a one way hash and a masked copy.
Change the password for that site, and for every other site where you used the same password, starting with your email account. Turn on two factor authentication on your email and banking. Then follow the plan on this page, which adds steps based on the specific data that was exposed.
Not necessarily. It means your address was in a stolen dataset. If a password was also taken and you still use that password anywhere, those accounts are at real risk until you change it.
No. Once breach data has been copied and shared, it cannot be recalled. You can close the account with the breached company and ask it to delete your data, but the leaked copy stays in circulation. The practical defence is making the leaked data useless: new passwords, two factor authentication and a credit freeze where identity details were exposed.
It is slang for compromised or defeated. It became the common word for appearing in a breach through the Have I Been Pwned service, which popularised checking email addresses against breach data.
