About this app

Lock the apps you care about behind your own PIN, password or pattern — plus fingerprint or face unlock. The apps, passwords, places and photos you protect with PassNox never leave your phone: no account and no tracking.

🔒 LOCK ANY APP
• Choose exactly which apps need a password to open.
• Or let PassNox auto-detect sensitive apps — banking, messaging, wallets, authenticators — and lock them for you.
• Give an app its own separate password that even the main one can't open.

🛡️ BUILT FOR REAL THREATS
• Emergency password: under pressure, hand over a fake password. Everything appears unlocked, but it's a decoy — changes are discarded, and after a short window the app locks down hard. Only
your real password reopens it.
• Leave-the-area lockdown: after the emergency password, PassNox can wait until the phone has moved away before locking — so it never snaps shut while someone is still in front of you.
• Theft triggers: lock down automatically if the SIM is removed or swapped, or if a trusted device disconnects while the phone is grabbed.
• Anti-uninstall: stop a thief from simply removing PassNox.
• Catch intruders: snap a photo after repeated wrong attempts.

📍 TRUSTED PLACES
• Define a place once — like home or work — and choose which apps open without a password while you're there. Checked entirely on-device; your location never leaves the phone.

🔑 UNLOCK YOUR WAY
• PIN, password, or pattern, plus fingerprint or face.
• A recovery question so you're never locked out — handled on the device.

🤫 PRIVATE BY DESIGN
• No account, no ads, no tracking. Your lock is stored only as a cryptographic hash.
• Settings, photos and places stay on your device and are deleted when you uninstall.
• Available in English, Spanish, Portuguese, French, German, Italian, Russian, Turkish and Indonesian.

PassNox keeps your private apps private — simply, and on your phone.

♿ ACCESSIBILITY SERVICE
• PassNox uses Android's Accessibility Service for one core purpose: to detect
which app is currently in the foreground. This is the only reliable way to
know the moment a protected app opens, so PassNox can show its lock screen in time — without it, locking cannot work.
• The same foreground signal also lets PassNox guard the system screens a thief would use to disable it (the device-admin and accessibility settings), which powers the anti-uninstall protection.
• PassNox does not read, collect, log or share the content of your screen, and
this information never leaves your device.
