Calculator - Secure Vault

What it does

SecureVault looks like a normal scientific calculator, but a secret code unlocks a zero-knowledge encrypted vault underneath. Unlike typical “hidden vault” apps, it’s fully functional on the surface and completely discreet. All encryption happens locally with AES-256-GCM, no cloud, no accounts, no tracking. Import and organise photos, videos, and documents, with instant re-lock and stealth features that keep your private files invisible — even if someone’s looking over your shoulder.
