Instant results. No sign-up. We scan 12 billion records across 700+ known data breaches and tell you exactly what leaked — and the exact steps to protect yourself.
What to do right now
Change your password on every affected site immediately — especially if you reuse it elsewhere.
Enable two-factor authentication (2FA) on those accounts so even a stolen password can't be used.
Use a unique password for every site going forward. A password manager makes this effortless.
Monitor your bank and credit accounts for any unusual activity over the next 30 days.
Use unique passwords
One breach shouldn't expose all your accounts. Use a different password for every site.
Enable 2FA everywhere
Two-factor authentication stops account takeovers even if your password is stolen.
Check your password too
Even if your email is clean, your password may have appeared in a breach elsewhere.
Check back regularly
New breaches surface constantly. A clean result today doesn't guarantee tomorrow.

Private by designData breach explained
Plain answers to the questions people actually search for.
A data breach occurs when hackers gain unauthorised access to a company's database and steal personal information. That stolen data — your email, password, phone number or financial details — is typically sold on the dark web and used for identity theft and account takeovers.
Enter your email in the checker above. We instantly search it against 12 billion leaked records from 700+ known data breaches. No account required, nothing stored. Results appear in under 2 seconds.
It means a company you have an account with was hacked and your data was stolen. Depending on what was exposed, attackers may have your password, phone number or financial details. Change your password immediately and enable two-factor authentication.
Yes — completely safe. We use a technique called k-anonymity. Your password is hashed in your browser and only the first 5 characters of that hash are sent to the database. Your actual password never leaves your device and is never visible to anyone.
A clean result means your email wasn't found in any known public breach today. It doesn't guarantee complete safety — new breaches are discovered constantly and some take months to become public. Check back regularly and always use strong, unique passwords.
Yes — severity depends entirely on what type of data was exposed. Financial data (credit cards, bank accounts, SSNs) is the most serious — act immediately and consider a credit freeze. Passwords require an immediate change on the affected site and every site using the same password. Emails and phone numbers are lower risk but increase your exposure to phishing. Every result on this tool includes a HIGH, MEDIUM or LOW risk rating so you always know how urgently you need to act.
