DataVault: Photo & Video Vault

📜 DataVault: Photo & Video Vault

Need a private, secure space on your phone? DataVault is your trusted privacy companion — designed to hide photos, videos, and personal files safely inside an encrypted vault, fully protected from prying eyes. Whether it’s personal memories, confidential documents, or sensitive videos, DataVault keeps everything private, secure, and under your control.

🔒 Core Features (Free)

Secure File Vault: Lock and hide your private photos, videos, and files with strong encryption. Files are never uploaded — all encryption happens on your device.

Powerful In-App Viewers: View your media directly in the vault — including photos, videos (via Media3/ExoPlayer), and PDFs — without exposing them outside.

Smart File Management: Rename, organize, and sort files easily by name, date, or size with smooth grid or list views.

Simple Import & Export: Import content directly from your gallery or other apps, and export securely when you choose.

PIN & Password Lock: Protect your entire vault with a secure password or PIN. Access requires authentication every time.

📳 Privacy Gestures: “Shake to Lock” and “Flip to Lock” instantly secure your vault.
🚫 Ad-Free Mode: Remove all ads for a distraction-free experience.
🧠 How Our Security Works

We believe in complete transparency and modern cryptographic design:

Local Encryption Only: All file encryption and decryption occur 100% on your device — never on our servers.

Authenticated Encryption: Each file is encrypted using AES-256-GCM for integrity and confidentiality.

Smart Data Strategy:

Files 5MB and smaller use AES-256-GCM.

Files larger than 5MB (like videos) use Google Tink’s Streaming AEAD (AES256-GCM-HKDF-4KB) — enabling efficient, secure on-the-fly streaming.

Strong Key Derivation: Your master password derives a 256-bit encryption key using PBKDF2 with 65,536 iterations, making brute-force attacks highly impractical.

You Hold the Key: Your password is never stored or transmitted. If lost, we cannot recover it — ensuring only you have access.

🔐 Privacy & Transparency

No Analytics: We do not track, profile, or analyze user behavior.

Local Operations: Your files never leave your device unless you explicitly back them up.

Secure Connections: All data transfers (ads, optional cloud sync) use HTTPS encryption.

AdMob Integration: The free version uses Google AdMob to display non-intrusive ads. Google may collect limited, anonymized identifiers for ad delivery and measurement.

Pro Version: Fully removes ads and external network connections.
