Store description excerpt
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 Not affiliated with Have I Been Pwned. Leak data is derived from their public corpus.
