KryptaVault: Encrypted Vault

KryptaVault is a next-generation personal security vault engineered with Zero-Knowledge architecture and military-grade End-to-End Encryption (E2EE) to guarantee absolute privacy for your personal files and notes.

Unlike traditional cloud services where providers can scan, analyze, or leak your data, KryptaVault encrypts 100% of your data client-side before upload. Neither our servers nor developers can ever view your files or unlock your vault.

CORE FEATURES:

1. MILITARY-GRADE ZERO-KNOWLEDGE ENCRYPTION
- Proven cryptographic standards: Argon2id KDF coupled with AES-256-GCM (Authenticated Encryption).
- Deterministic 12-Word BIP-39 Mnemonic Recovery Phrase (same standard as hardware crypto wallets).
- No master keys or plaintext passwords ever reach our servers. Only you hold the key.

2. STEALTH CAMOUFLAGE MODE
- Disguise the app icon and name on your home screen as a fully functioning Calculator, Notes, or Weather app.
- Built-in working calculator interface: Enter your secret PIN to seamlessly unlock your private vault.

3. ENCRYPTED MULTIMEDIA VAULT & PRIVATE NOTES
- Lock and protect photos and 4K videos in original quality without compression.
- Secure scratchpad note editor with real-time in-memory keystroke encryption.
- Store sensitive PDF contracts, financial records, and confidential documents.

4. ACTIVE RAM HYGIENE (MEMORY ZEROIZATION)
- Secret key buffers in memory are immediately overwritten with zeros upon vault lock or logout.
- Auto-lock timer activates whenever you switch apps or lock your device screen.
