BLACKBOX is a clean, lightweight, offline-first security hub built for developers, creators, and anyone who values digital privacy. All data is encrypted with AES-256-GCM and stored on your device — nothing ever leaves without your explicit consent.Core Modules:
- Secrets Manager: Store API keys, passwords, and tokens in categorized, encrypted vaults. Tap-to-reveal and one-tap copy.
- Encrypted Journal: Timestamped entries with category tags, all encrypted locally with your master PIN.
- 2FA / Authenticator: TOTP code generator with live countdown and manual secret entry. No cloud sync, no accounts needed.
- Privacy Tools: Permission audit, tracker URL cleaner, browser fingerprint viewer, and malicious URL scanner.
- Settings: Master PIN change, auto-lock timer, biometric unlock, panic mode with decoy calculator, screenshot blocking.
Security Features:
- AES-256-GCM encryption via Web Crypto API
- PBKDF2-SHA256 key derivation with 150,000 iterations
- FLAG_SECURE screenshot and screen recording blocking
- Biometric unlock (fingerprint / face) via Android BiometricPrompt
- Panic mode: calculator decoy triggered by PIN prefix
- Auto-lock on inactivity or app switch
- 100% offline — no network calls, no analytics, no tracking
BLACKBOX is free, open-source, and built with Capacitor for Android. No proprietary dependencies. No cloud. No compromises.
WhatsNew:
Two important fixes. 2FA codes now actually appear: a bug made every code show dashes, so the authenticator could not be used. And deleting an item while in the decoy vault no longer wipes your real vault. If you use the decoy PIN, please update.
While you can download the APKs here directly, you should preferably use an F-Droid client so the app stays up-to-date on your device.
