Email breach check
Has your email been in a breach?
Enter your email address to see whether it appears in any known data breach - and exactly which ones, so you know where to change your password.
How this protects your privacy
- Your email is sent only to look up breaches (via XposedOrNot) and is used for nothing else.
- Cactus never stores or logs the address, and there's no account or sign-up.
Frequently asked questions
Does Cactus store my email address?
No. Your email is sent only to look up known breaches and is never stored or logged, and there's no account or sign-up.
What should I do if my email was found in a breach?
Change your password on the affected sites - and anywhere you reused it - turn on two-factor authentication, and watch for phishing that uses your leaked details.
Does "no breaches found" mean I'm safe?
Not entirely. Not every breach is public or indexed, so a clean result isn't a guarantee. Keep using a unique password for every account and enable two-factor authentication.
