Free Have I Been Pwned Alternative: ARK Mobile Security Check
ARK gives your iPhone a security credit score from 0-100 and checks whether your data appeared in known breaches via HIBP integration. It's a free, privacy-first alternative that scans device security, network exposure, and app permissions in one place, all on your phone.
What ARK Does Differently
Unlike a single breach-checking website, ARK combines breach monitoring with a full device security audit. You get one score that reflects your overall security posture: device vulnerabilities, insecure permissions, network risks, and breach exposure all rolled into a 0-100 credit score. The app runs entirely on-device, so your data never leaves your phone. You can run a quick scan for free and see your score instantly, without creating an account.
Breach Monitoring Built In
ARK checks your email and known usernames against breach databases, similar to Have I Been Pwned, but as part of a broader security assessment. Once you know you're in a breach, the app doesn't stop there. It gives you one-tap remediation guidance: which passwords to change, which apps to review, and what settings to tighten. The free tier includes this core scanning; the Pro tier adds continuous monitoring so you're alerted when new breaches surface.
One Security Score, Not Separate Tools
Rather than jumping between a breach checker, a password auditor, and a device scanner, ARK brings everything into a single 0-100 score. It scans CVE vulnerabilities on your installed apps, examines app permissions, checks Wi-Fi network security, and evaluates your device settings all at once. The result is a straightforward number that tells you how secure your phone actually is, and exactly what to fix.
Who Should Use ARK
If you've been in a data breach, use ARK to see what exposure remains on your device and what to do about it. Privacy-conscious users appreciate that it's on-device with no account required. Parents can use the Pro tier to monitor family devices. Small business owners running multiple iPhones can spot security gaps across the team. Anyone who wants a single, actionable security snapshot instead of hunting through separate tools will find it faster here.
Free and Pro Tiers
The free tier gives you unlimited device scans, breach checking, and remediation guidance. The Pro tier unlocks continuous breach monitoring so you're notified if your data appears in new breaches, plus the ability to monitor family members' devices from one dashboard. Start with the free scan. If you want ongoing peace of mind, upgrade to Pro.

Frequently asked questions
Is ARK the same as Have I Been Pwned?
No. ARK uses HIBP data for breach checking, but it's a full device security score tool that also scans permissions, CVEs, and network security. HIBP is a website that checks one email; ARK is a mobile app that checks your entire device security posture in one score.
Does ARK require an account?
No. The free tier requires no sign-up. You download, scan, and see your security score instantly. Pro features use optional account login for continuous monitoring across devices.
Is my data sent to ARK servers?
No. All scanning happens on your phone. Your data never leaves the device. ARK is fully on-device by design, so your breach check and security assessment stay private.
What if ARK finds a breach?
ARK shows you which accounts are exposed and gives one-tap remediation links to change passwords and secure those accounts. Pro tier sends alerts if your data appears in new breaches.
Can I use ARK on Android?
ARK is available on iOS only.
Is ARK a VPN or antivirus?
No. ARK is a security credit score tool. It assesses your device's security posture, scans for breaches and vulnerabilities, and guides you to fix them. It's not a VPN, antivirus, or replacement for those tools.
