Lumin

Security First · Full-File Encryption · Private and Controlled

Luguang uses file-level encryption. All data backed up to the USB drive is encrypted and can only be accessed through the dedicated app after decryption.

Key Features

🔐 All files are encrypted before being stored on the USB drive

🧩 One File, One Key (each file encrypted independently)

👤 Account registration required

🔒 App lock supported (authentication required to enter)

📂 Supports backup of photos, videos, documents, and audio files

🛡 If the USB drive is lost, data cannot be accessed directly

---

Performance Notes

Because encryption is applied during the writing process:

• Write speed is slightly slower than the Lite version

• Files must be decrypted before being viewed

This is the necessary computational cost of stronger data protection.

Ideal For

• Storing work files, contracts, certificates, or other sensitive documents

• Users with high privacy and security requirements

• Anyone who wants data to remain protected even if the USB drive is lost
