[BETA] LeakGuard — Check if your password has been leaked (privacy-first, no signup required)
Hey everyone,
I built LeakGuard, an iOS app that checks if your password has appeared in known data breaches using the Have I Been Pwned database.
Why I built it:
Most people reuse passwords across sites. One breach = all accounts at risk.
How it works:
• Your password is hashed on-device (SHA-1)
• Only the first 5 characters of the hash are sent to the API (k-anonymity)
• The full password NEVER leaves your device
Features:
✅ Instant password breach check
✅ Secure password generator
✅ Check history (stored locally, encrypted)
✅ No account required
✅ No tracking, no analytics
Looking for beta testers to squash bugs and suggest features before launch.
Feedback welcome! 🙏
