GhostCore

GhostCore - Your Device, Your Private Vault
In a world where cloud services are everywhere, GhostCore takes a different approach.
GhostCore is a local-first encrypted privacy vault designed for people who value control over their personal data. No accounts. No servers. No cloud synchronization.
Your notes, photos, and files remain on your device, under your control.
AES-GCM Local Encryption
GhostCore uses AES-GCM encryption to protect your data.
All content is encrypted before storage and can only be accessed after successful authentication.
Your data is never uploaded to external servers or shared with third parties.
Multi-Layer Security Protection
Choose from multiple authentication methods:
Face ID / Touch ID
Custom Gesture Lock
Backup PIN Code
Combine multiple layers of protection to match your personal security preferences.
Secure File & Attachment Storage
Store and protect:
Photos and Images
PDF Documents
Office Files
Other Common File Formats
Imported attachments are encrypted and securely managed within the app.
Auto-Lock & Privacy Protection
GhostCore includes built-in automatic locking features.
Customize your preferred lock interval:
15 Seconds
30 Seconds
1 Minute
3 Minutes
The app can automatically lock when sent to the background or after a period of inactivity.
Privacy masking helps reduce information exposure in app switcher previews.
Multi-Language Support
GhostCore natively supports:
English
Simplified Chinese
Japanese
Korean
Combined with a clean, distraction-free interface, GhostCore delivers a focused and secure user experience.
Important Notice
GhostCore is built on a local-storage architecture.
Your data is not synchronized to cloud servers.
If the app is deleted or the device is replaced, data that has not been exported may not be recoverable.
We strongly recommend exporting and backing up important content regularly.
Designed For Ultimate Use Cases
GhostCore is built for scenarios where data leakage is not an option:
Crypto & Web3 Security: Safely store your hardware wallet backup phrases, mnemonic seeds, and private API keys without worrying about clipboard snooping or server breaches.
Private Journaling & Memos: Write your absolute private diaries, personal logs, or sensitive financial notes in an offline notepad that nobody else can access.
Confidential Documents: Keep scans of your passport, ID cards, contracts, or confidential business proposals fully locked and encrypted on-device.
Frequently Asked Questions
Q: Where is my data stored?
A: Your data is stored exclusively within your device's secure local sandbox. GhostCore has no remote servers, no databases, and no network protocols to transmit your content.
Q: What happens if I forget my password or PIN?
A: Because GhostCore follows a strict zero-knowledge architecture, we do not store your credentials anywhere. If you forget your access keys, nobody can unlock your data—not even us. Your security is absolute.
Q: How can I migrate my data to a new device?
A: You can securely export your files and data manually through the built-in encrypted backup feature, allowing you to move your vault to another device completely under your own supervision.
