NC Lock

NC Lock is a private, offline vault that keeps your sensitive photos, videos, and PDF documents locked away with AES-256 encryption — the same standard trusted by banks and governments.

Your files never leave your device. NC Lock has no internet access, no ads, no tracking, and no cloud. Everything happens locally on your phone.

KEY FEATURES
━━━━━━━━━━━━━━━

🔒 AES-256 encryption
Every file is encrypted on your device before it's stored. Without your password, the contents are unreadable.

🖼 Photos, videos & PDFs
View everything inside the app — swipe through photos, play videos, and read PDFs in the built-in viewer. Your files never open in other apps.

📁 Folders
Organise your vault into folders. Move files between them and keep everything tidy.

🔍 Search, sort & view
Find any file by name across your whole vault. Sort by name, date, size, or type, and switch between grid and list layouts.

🔑 Flexible recovery
Optionally set a recovery code, security questions, or a master password — so a forgotten password doesn't mean lost files.

👆 Biometric unlock
Open your vault instantly with your fingerprint or face.

🔐 Auto-lock
The vault locks itself the moment you leave the app or your screen turns off.

🙈 Hidden from Gallery
Encrypted files are invisible to your Gallery and every other app on your phone.

🌗 Light & dark theme
NC Lock automatically matches your phone's system theme.

📴 Completely offline
No internet permission. No ads. No analytics. No tracking. Ever.

━━━━━━━━━━━━━━━
YOUR PRIVACY IS THE PRODUCT
━━━━━━━━━━━━━━━

NC Lock collects nothing. No personal data, no usage stats, no crash reports. The app cannot send your data anywhere because it has no internet access — and you can verify this yourself in your phone's permission settings.

IMPORTANT
━━━━━━━━━━━━━━━

NC Lock has no backdoor. If you forget your password and haven't set up a recovery option, your files cannot be recovered by anyone — not even us. This is exactly what keeps them private. Please set up at least one recovery method and keep it somewhere safe.
