Bunker Note

Bunker Note is your Secure Note Bunker for your texts, diaries, and more.

Unlike other apps, Bunker Note is 100% Local and Offline. It requires no internet connection, does not sync with any cloud, and has no hidden servers. Your information never leaves your device.

🛡️ INDUSTRIAL-GRADE SECURITY

Advanced Hybrid Encryption: Your notes are protected using industrial standards, combined with multiple layers of dynamic obfuscation.

Integrity Signatures (HMAC): Every file is cryptographically sealed. If someone attempts to tamper with your note file from outside the app, the system will detect it and block access.

Double Password Mode: For extreme security, you can configure the app to require two distinct master passwords to decrypt a file.

🚫 ABSOLUTE PRIVACY

Zero Data Collection: We do not ask for your email, there is no account registration, and we do not track your usage habits.

Screenshot Blocking: While you edit or read your confidential notes, the operating system will prevent screenshots or screen recordings (native security feature).

Brute-Force Anti-Theft: The system features an automatic temporary lockout that activates after 3 failed password attempts.

⚙️ KEY FEATURES

Dark Mode interface: clean and distraction-free.

Strong password requirements (minimum 12 characters, uppercase and lowercase) to ensure high entropy and make unauthorized decryption mathematically unfeasible.

Manual Backup Tool: Export your encrypted notes in a secure .fvbkhp file to save wherever you choose.

⚠️ IMPORTANT - YOUR SECURITY IS YOUR RESPONSIBILITY

Since Bunker Note does not store your keys in any database, there is no "Forgot my password" button. If you lose your 12-character password, it will be mathematically impossible to recover your notes. We recommend keeping your master key safe and performing periodic backups with the Backup tool included in the settings.
