Privacy & data breach monitoring

Check if your data has been leaked.

One scan shows which data breaches contain your email address and passwords. Breach Watchdog then monitors your profile and alerts you to every new breach.

Eight features.
One secure overview.

Breach Watchdog combines eight features in one app, so you don't have to worry about data breaches.

[01]

Email breach check

See which data breaches contain your email address and what data was leaked. Combines Have I Been Pwned, LeakCheck and XON.

[02] // risk score

Personal risk score

A clear meter shows how high your risk is. An attack profile shows what cybercriminals can know about you.

[03]

Password check

Check if your password has been leaked — without it leaving your device. Only a partial hash is sent via k-anonymity.

[04]

Breach Monitor

Add email addresses and automatically receive a notification when a new data breach is discovered, with a widget on your home screen.

[05]

URL scanner

Check if a link is safe before clicking it. Scans for malware, phishing and other threats via Google Web Risk.

[06]

Domain check

See if a domain is protected against email spoofing. Checks SPF and DMARC records and shows WHOIS information.

[07]

Smart advice

Not every breach requires the same action. Breach Watchdog recognises old or defunct platforms and adapts the advice accordingly.

[08]

Privacy first

No account. No storage of emails. Passwords never leave your device.

FAQ

The essentials on security and privacy.

Is it safe to enter my email address?

Yes. Your email address is only used to check if it appears in known data breaches. We don't store it, don't link it to an account and never sell it. The check runs via encrypted connections to external sources like Have I Been Pwned, LeakCheck and XON — once the result is on your screen, nothing of your address has been saved. You also don't need an account: the app works completely without registration.

How do you check my password safely?

Your password is converted on your device into an unreadable string of characters — a fingerprint of your password, but not the password itself. We then only send the first five characters of that string. That's enough to compare with a database of leaked passwords, but far too little for anyone else to do anything with. Your real password never leaves your device.

Which sources do you use?

Breach Watchdog combines Have I Been Pwned, LeakCheck and XON for email data breaches, and Google Web Risk for the URL scanner.

What does the Breach Monitor do?

The Breach Monitor keeps up to five email addresses under continuous surveillance. As soon as one of those addresses appears in a new data breach, you immediately receive a notification on your phone. So you don't have to scan periodically yourself — the app does it for you, in the background. Via the widget on your home screen you can see at a glance whether everything is still safe.

Is there a free version?

Yes. The free version includes 2 email scans, 2 password checks, 2 URL scans and 2 domain checks — enough to get started. Pro gives you unlimited access.

Is there a free trial?

Yes. Pro comes with a 14-day free trial — you're not charged during those 14 days. Google Play does require a payment method to start the trial, and billing begins automatically afterward unless you cancel.
