GridVault - Offline Crypto&PW

🇩🇪 German

GridVault – Your Secrets. Off the Grid.

GridVault isn't your typical cloud password manager. It's a high-security application for cold storage backups. We transform your most sensitive data (crypto seeds, bank logins, 2FA codes) into encrypted "SafeSheets"—inconspicuous grids of letters that you print and physically secure.

Why GridVault?

🔒 Unhackable: Paper can't be hacked. No cloud, no servers, no internet access required.

🕵️ Steganography: Your data is hidden as "noise" in a random grid. Even if someone finds the sheet, they'll only see gibberish.

🛡️ Military-grade: AES-256 encryption before the grid is generated.

App Plausible Deniability (James Bond Mode): Are you being forced to open the app? Enter a fake PIN! GridVault displays credible fake data. Your real data remains invisible.

Use Cases:

• Crypto Investors: Secure your seed phrase (12/24 words) so that a burglar can't decipher the piece of paper.

• Preppers: A backup that works even during power outages, EMPs, or internet shutdowns (thanks to its analog coordinate system).

• Digital Estate Management: Share your grid and PIN between two trusted individuals.

Features:

• Scan & Go: Decrypt your paper backups in a flash with your camera.

• App Wallet: Store your most important documents encrypted on your phone for on-the-go access.

• Backup: Export your wallet as a file for easy transfer between devices.

Limitations:

Due to the physical limitations of QR codes, a maximum of approximately 500 characters can be stored per document. If you forget your PIN, the data will be irrevocably lost. There is no back door.

GridVault – Your Secrets. Off the Grid.

GridVault is not a cloud password manager. It is a specialized security tool for "Cold Storage" backups. We convert your most critical data (Crypto Seed Phrases, Bank Logins, 2FA Backup Codes) into encrypted “SafeSheets” – chaotic grids of characters that you print out and store physically.

Why GridVault?

🔒 Un-hackable: Paper cannot be hacked remotely. No Cloud, No Servers, No Internet permission.

🕵️ Steganography: Your data is hidden inside a random grid of characters. Even if someone finds the sheet, they only look gibberish.

🛡️ Military Grade: Your data is encrypted with AES-256 before being generated into the grid.

🎭 Plausible Deniability (Panic Mode): Forced to open the app? Enter a fake PIN! GridVault will generate plausible fake logins to display on your real grid. Your real data remains invisible.

Use cases:

• Crypto Investors: Secure your Seed Phrase (12/24 words). A simple paper note is unsafe; a SafeSheet requires your PIN to be readable.

• Preppers: A backup strategy that works during blackouts, EMPs, or internet shutdowns (via analog coordinates).

• Digital Legacy: Split the Grid and the PIN between two trusted parties.

Features:

• Scan & Go: Decrypt your paper backups instantly using the camera.

• App Wallet: Keep your most important sheets encrypted on your phone for quick access.

• Backup & Sync: Export your wallet to transfer data between Android and Desktop securely.

Security note:

Due to physical QR code limitations, one sheet holds approx. 500 characters. If you forget your PIN, your data is lost forever. There is no backdoor.
