S.I.G. Personal Vault

S.I.G. Personal — Your Personal Data Vault

S.I.G. Personal encrypts your files directly on your Android device. Documents, photos, passwords, personal records — everything that is meant for your eyes only.

Fully offline

The app requires no internet connection and no server. No registration, no account, no cloud required. Your data only leaves your device when you explicitly choose to share it.

Three-factor protection
Your vault is secured by three independent factors: your personal certificate (Certificate.bin), your individual master key (Masterkey.json) and your password. All three must come together to gain access.

Your personal key
Every S.I.G. package is unique. The master key is calculated once exclusively for you and is mathematically bound to your certificate. No other certificate can open your vault.

Encrypted file format
Encrypted files are stored in the proprietary .spv format. This format can only be opened by S.I.G. Personal.
One-time purchase — no recurring costs
S.I.G. Personal is a one-time purchase. No subscriptions, no hidden costs.
Important notice

Leue Research Germany has no access to your data and cannot recover lost access credentials. Please store your access files securely. If you lose your certificate, master key or password, access to your encrypted data is permanently lost.
