Sentinel: The Ultimate Offline-First Encrypted Vault

Managing hundreds of accounts makes remembering strong, unique passwords humanly impossible. Sentinel is a next-generation digital vault engineered to solve this crisis, combining credential storage, built-in 2FA, financial data protection, and secure collaboration into one elegant, zero-knowledge application.

Privacy First: Zero-Knowledge Architecture

Built on a strict offline-first philosophy, Sentinel ensures your data belongs entirely to you.

* Local AES-256 Encryption: Your information is encrypted directly on your hardware.
* Immune Cloud Backups: Backups to your personal Google Drive are heavily encrypted before they leave your device. Google, hackers, and even Sentinel's developers have zero visibility.

All-in-One Credential & 2FA Management

Sentinel streamlines your daily security workflows, eliminating the tedious friction of traditional tools:

* Visual Organization: Automatically fetches high-resolution website logos and offers custom tagging to cleanly separate work, personal, and financial data.
* Integrated Authenticator: A built-in QR scanner generates time-based 2FA tokens directly alongside your logins—no more frantic app-switching.
* Password Health Audits: An offline engine continuously analyzes your vault, flagging weak or reused credentials to keep you ahead of cyber threats.

Secure Sharing and Hardware Integration

* RSA Cryptography: Share credentials safely. Sentinel encrypts data using the recipient’s public RSA key, ensuring it is mathematically locked during transit and only readable by the intended user.
* Biometrics & Cross-Platform Sync: Access your vault instantly via Face ID, Touch ID, or Android Fingerprint. Built with React Native, it bridges ecosystems seamlessly between iOS and Android.

Regain absolute digital sovereignty. Your keys, your data, your Sentinel.
