Is your email in a data breach?
Enter your email address and we query public breach sources in real time. We tell you whether it appears, in which breaches, from what date and which data types were affected. We never show passwords or leaked data, and we do not store your email.
Privacy: we do not store your email or the results. The lookup runs in real time against public sources and is discarded afterwards. We only keep an anonymous counter (hash) for the daily quota.
Data courtesy of the linked sources. We only show membership and metadata: never passwords or fragments of the leaked data.
Breach-Check
Check whether your email appears in data breaches
Thousands of data breaches become public every year: user databases stolen from online shops, social networks, forums and companies of every kind. If your email address was in one of them, your data (and often your passwords) is circulating on the internet. This tool tells you in seconds and for free whether your email appears in known breaches — no sign-up, and we never store your address.
How it works
Step 1 · Enter your email. A single field. The anti-bot check is invisible in most cases.
Step 2 · We query public sources in real time. We ask public breach databases and an index of devices infected by credential-stealing malware (infostealers).
Step 3 · Full result, free. We show you which breaches your email appears in: the breach name, the date and the affected data types (for example: email addresses, passwords, phone numbers). No paywalls, no half results.
Which sources we check
- XposedOrNot — a public database with thousands of indexed breaches.
- Hudson Rock — intelligence on devices infected by infostealers (malware that steals credentials saved in the browser).
- Have I Been Pwned — integration ready; coming soon.
Source attribution is always shown next to the result. If a source is unavailable at that moment, we tell you clearly: we never make up results.
What we do NOT do (privacy)
- We do not store your email. The lookup runs in real time and is discarded afterwards.
- We do not store the results. Only an anonymous counter (hash) for the anti-abuse daily quota of 5 checks per day.
- We never show passwords or fragments of the leaked data. Only whether you appear, where, and which data types were affected.
What to do if your email appears in a breach
1. Change the password of the affected accounts — and anywhere else you reuse the same one.
2. Enable two-factor authentication (2FA) on your email, banking and social accounts.
3. Use a password manager to generate a unique password per service.
4. Watch out for targeted phishing: attackers use leaked data to write very convincing emails.
