About this app

True File Locker protects your private files with military-grade AES-256-GCM encryption. Your photos, videos, and documents are locked behind a secure vault that only you can access.

🔐 BANK-LEVEL ENCRYPTION
Every file is encrypted with AES-256-GCM — the same standard used by banks and governments. Each file gets its own random initialization vector, making your data virtually impossible to crack.

🔑 ZERO-KNOWLEDGE SECURITY
Your password never leaves your device. It's processed through PBKDF2-SHA256 with 600,000 iterations to derive your encryption key, which exists only in memory while the app is unlocked. We can't access your files — only you can.

🛡️ BRUTE FORCE PROTECTION
Built-in protection against unauthorized access attempts. After failed password entries, the app enforces increasing lockout periods. Too many attempts? The vault locks permanently until you choose to reset.

📁 PROTECT ANY FILE TYPE
• Photos — Import from your gallery
• Videos — Secure your private recordings
• Documents — PDFs, ZIPs, APKs, and more

All imported files are encrypted instantly and stored in a private directory inaccessible to other apps.

🔒 HARDWARE-BACKED SECURITY
Cryptographic keys and authentication data are stored in your device's Android Keystore — a tamper-resistant, hardware-backed secure enclave.

🌍 21 LANGUAGES SUPPORTED
English, Hindi, Bengali, Portuguese, Russian, Japanese, German, Korean, French, Spanish, Arabic, Urdu, Chinese, Indonesian, Turkish, Vietnamese, Swahili, Punjabi, Marathi, Telugu, and Tamil. Full RTL support for Arabic and Urdu.

🚫 NO DATA COLLECTION
True File Locker does not collect, store, or transmit any of your personal data. No accounts, no cloud sync, no analytics, no tracking. Your files stay on your device — period.
