A breach notice leaves out the next step

You get told your details were caught up in a breach, but not which breach, what it exposed, or what to do first.

Most breach notices are short on detail. They name a company, maybe a date, and leave you guessing about the rest.

We fill the gap. A data breach check shows the publicly known breaches linked to your email and spells out what each one exposed, from passwords to phone numbers and dates of birth.

From there you get a plain plan, most important steps first, so you fix the things that matter before the smaller ones. We never search, buy or hold stolen data, and we cannot remove your details from a breach, so the advice is honest about what you can and cannot change.

How a data breach check works, step by step

Three plain stages take you from a worried question to a clear plan you can act on today.

  1. Check

    Enter your email address. We check it against publicly known breaches and show which ones it appears in. No account, no payment, and no sign-up required to see your result.

  2. Understand

    Each result lists what that breach exposed, such as passwords, email addresses, phone numbers or dates of birth, and explains in plain words what that means for you and which risks matter most.

  3. Fix

    Follow the plan in order: secure your email account first, change any reused passwords, turn on multi-factor sign-in, then stay alert for scam messages that use the leaked details to sound convincing.

Frequently Asked Questions

Is it safe to enter my email?
You can enter your email without creating an account or paying. We store the address only as a masked version and a one-way hash, never in full. A hash is a scrambled fingerprint that cannot be turned back into your address. We never sell it or share it.
Do you store my address?
Not in full. When you run a check we keep a masked version and a one-way hash so the tool can work, and we do not keep the plain address. If you create a free account later, you can download or delete everything we hold at any time.
What does it mean if I am found?
It means your email appears in one or more publicly known breaches. The result lists what each breach exposed, such as passwords or phone numbers. An empty result is not proof you were never exposed, since not every breach is public. Either way, secure your email, change reused passwords and turn on multi-factor sign-in.
Is it really free?
Yes. The breach check and the security tools are free to use, and you do not need an account to run a check. We have no paid plan of our own. A free account is optional and adds daily alerts, incident notes and saved domains.
How do you make money?
Some outbound links to protection services are affiliate links, which means we may earn a commission if you sign up through them. We disclose this next to the link. It never changes what you pay, and we never tell you a paid service is necessary. The free step always comes first.
