Deadlock: Data Security
Protect Your Digital Life
Free · Designed for iPad. Not verified for macOS.
Is your email in a data breach? Find out in seconds. Scan emails, check passwords, verify QR codes & links — all free, all private. Your security starts here.
Deadlock is your all-in-one digital security toolkit. Scan your email for data breaches, check password strength, verify QR codes and URLs before opening them, and analyze your Wi-Fi network security — all in one app.
- Email Scanner
Enter your email address and instantly find out if it appears in known data breaches. See which companies were compromised, what data was exposed, and get step-by-step remediation guides to secure your accounts.
- Password Checker
Test any password's strength with real-time crack time estimates. Check if your passwords have been found in breach databases using the Have I Been Pwned API. Generate strong, random passwords with one tap.
- QR Code Scanner
Scan any QR code with your camera and Deadlock will check the destination URL against Google Safe Browsing before you open it. Safe links show green, dangerous ones show red — so you know before you click.
- URL Safety Checker
Paste any link and check it against threat databases. Deadlock identifies phishing sites, malware distribution pages, and social engineering attacks before they can harm you.
- Network Scanner
Analyze your current Wi-Fi connection for security issues. Check encryption type, identify open networks, and get recommendations to improve your network security.
- Auto-Monitor
Add your email addresses and receive background alerts whenever a new breach is detected. Stay protected without even opening the app.
Security Score
Track your overall security posture with a score based on your scanning activity, password hygiene, device security settings, and app usage.
All features are completely free. No subscriptions, no paywalls, no ads. Your data never leaves your device.
