## What is LeakGuard?

Instantly check if your passwords appeared in known data breaches  without ever sending your password anywhere.

LeakGuard uses k-anonymity technology to check your passwords against over 800 million known breach records. Only the first 5 characters of a scrambled hash ever leave your device. Your actual password stays on your iPhone. Always.

HOW IT WORKS
1. Enter any password
2. LeakGuard computes a partial fingerprint on-device
3. Only 5 characters of that fingerprint are sent to the breach database
4. Your result comes back in seconds — safe or compromised

Your password is never transmitted. Not even close.

BREACH CHECKER
• Check any password against 800M+ known breach records
• Instant results in under 3 seconds
• Full offline privacy — nothing sensitive leaves your device
• Free: 5 checks per day

PASSWORD GENERATOR
• Cryptographically secure generation via SecRandomCopyBytes
• Custom length (8–64 characters), symbols, numbers, mixed case
• Presets: Standard, Memorable, Wi-Fi, PIN, Apple ID
• Excludes ambiguous characters (0, O, l, 1, I) for readability

STRENGTH METER
• Real-time scoring from 0–100
• Detects sequential patterns, repeated characters, and common passwords
• Checklist: see exactly what makes a password weak or strong

CHECK HISTORY
• Stores only a cryptographic hash — never plaintext
• See which passwords were safe vs. compromised over time
• Fully local: no cloud sync, no server storage

COMING SOON: EMAIL BREACH MONITORING
• Check if your email addresses appeared in known data breaches
• Get notified when new breaches are discovered
• Sign up inside the app to be notified at launch

PRIVACY FIRST
LeakGuard was built around one principle: your secrets never leave your device. We use the industry-standard k-anonymity model from Have I Been Pwned — the same technology trusted by millions worldwide and built into Apple's Password Manager.

• No account required
• No data stored on any server
• No third-party analytics with personal data
• An open privacy model you can verify yourself
