## What is Leak Lens?

Check if your password has appeared in a data breach — without it ever leaving your phone. Test it in Airplane Mode.

Leak Lens ships a compressed index of the 30 million most common leaked passwords (from the public "Have I Been Pwned" corpus) inside the app. Your password is hashed on your device and checked locally. The app contains no networking code at all — nothing is sent anywhere, ever.

HONEST BY DESIGN
• A negative result is definite: your password is not among the 30M most common leaked passwords.
• A positive result is probabilistic: about 1 in 100 safe passwords is flagged by mistake. That's the trade-off that makes a fully offline check possible in 36 MB — and we tell you about it instead of hiding it.

FREE
• Unlimited offline leak checks
• Live strength meter with honest entropy estimates
• First weakness warning on every result

PRO — ONE-TIME PURCHASE, NO SUBSCRIPTION
• Full weakness breakdown + crack-time estimates
• Passphrase generator (EFF wordlist, up to 6 words)
• Batch check up to 20 passwords from your clipboard

PRIVACY
• No accounts, no analytics, no SDKs, no network access
• Passwords are wiped from memory when the app goes to background
• App Privacy label: Data Not Collected
