Breach WD: Data Breach Monitor

Breach Watchdog: protect your email, passwords and domain against data breaches. No account needed, install and you can start right away.

As the only app, Breach Watchdog combines three independent sources (Have I Been Pwned, LeakCheck and XON) for the most complete picture of your digital risk.


🔒 PRIVACY FIRST
We do not store your email addresses. Passwords never leave your device (k-anonymity method). All data is stored encrypted, locally on your device.

📡 BREACH MONITOR
Add email addresses and receive an instant notification as soon as a new data breach is discovered. Breach Watchdog monitors quietly in the background, with a widget on your home screen that shows at a glance whether action is needed.

🔍 EMAIL DATA BREACH CHECK
See in which data breaches your email address has been found, which data has been exposed (passwords, phone numbers, addresses, financial data and more) and receive personal action advice per breach.

📊 RISK SCORE
A personal risk score based on your leaked data, one of a kind. One clear gauge shows your risk at a glance, with an attack profile that reveals what cybercriminals may know about you.

🔐 PASSWORD CHECK
Check whether your password has been leaked, without it ever leaving your device.

🌐 DOMAIN AND URL SCANNER
Check whether an email domain is protected against spoofing via SPF and DMARC records. Scan suspicious links for phishing and malware before you click on them.

🧠 SMART ADVICE
Not every data breach requires the same action. Breach Watchdog recognises when a platform no longer exists or a breach is years old, and adjusts the advice accordingly. No unnecessary notifications, only relevant information.

💡 SECURITY TIPS
Practical tips about passwords, two-factor authentication, phishing, VPN, SIM swapping and more.

Free: unlimited email scans, instantly view your risk score and attack profile. For the full report (in which data breaches your data was found and what you need to do) you need Pro. Password checks, domain checks and URL scans are also unlimited.
