Browser-based AES-256 encrypted notes that never leave your device.

Secure Notes बारेमा
Secure Notes lets you write, encrypt, and store private notes entirely in your browser. Using military-grade AES-256-GCM encryption with PBKDF2 key derivation (100,000 iterations), your notes are locked behind a password that only you know.
Why Use Secure Notes?
Unlike cloud-based note apps, Secure Notes never sends your data to any server. Everything — encryption, decryption, and storage — happens locally in your browser using the Web Crypto API. Your notes live in localStorage and are completely device-specific.
- AES-256-GCM encryption with PBKDF2 key derivation
- Create, view, and delete encrypted notes with a simple interface
- Export all encrypted notes as a JSON backup file
- Session password memory for convenience during a browsing session
- No account required, no server uploads, 100% offline-capable
How It Works
Each note is encrypted individually with a unique salt and initialization vector. Even if someone accesses your device, they cannot read your notes without the correct password. There is no password recovery — if you forget your password, the note is permanently inaccessible.
Perfect for storing sensitive information like passwords, personal thoughts, private ideas, or confidential business notes that you want to keep completely private.
