GhostCore：Offline Crypto Vault

GhostCore - Your Device, Your Private Vault
Unlike mainstream cloud services, GhostCore is a local-first encrypted privacy vault for users who want full control over personal data. It requires no accounts, no servers, and no cloud sync. All your notes, photos and files stay locally on your device, fully owned and controlled by you.
AES-GCM Local Encryption
GhostCore adopts standard AES-GCM encryption for all data. All files are encrypted before local storage and only accessible after successful authentication. Your data will never be uploaded to external servers or shared with third parties.
Multi-Layer Security Protection
Secured by AES-GCM encrypted offline 2FA tokens and local QR scanning, the app supports flexible multi-authentication solutions for customized security:
- Face ID / Touch ID
- Custom Gesture Lock
- Backup PIN Code
Secure File Storage
GhostCore safely encrypts and manages all common file types, including photos, PDFs, office documents and other attachments. All imported files are fully encrypted and isolated in the app’s secure local sandbox.
Auto-Lock & Privacy Protection
Secure Camera, PDF Scanner & Audio Recorder built-in
Customizable auto-lock timers (15s/30s/1min/3min) enable automatic locking when the app is idle or sent to the background. Built-in privacy masking blurs content in app switcher previews to prevent information leakage.
Multi-Language Support
Native support for English, Simplified Chinese, Japanese and Korean. Paired with a clean, minimalist interface, it delivers a smooth, distraction-free secure user experience.
Important Notice
GhostCore applies a pure local-storage architecture with no cloud backup. If the app is deleted or your device is replaced, unexported data may be unrecoverable. Regular manual export and backup of important data is strongly recommended.
Core Application Scenarios
