How Secure Notes Work
A simple, transparent process for maximum security.
Write
Write your note securely in the browser editor.
Encrypt
Encrypt locally using your secret password.
Save/Share
Copy the encrypted block for safe storage or sharing.
Control
You keep full ownership of your data at all times.
Built with Modern Security Standards
SafeTools utilizes the highest standards of web cryptography to ensure your data remains inaccessible to everyone but you.
AES-256 Encryption
The gold standard of symmetric encryption used by governments worldwide.
Web Crypto API
Native browser-based cryptography ensuring no third-party JS library vulnerabilities.
Secure Sandboxing
Notes are processed in an isolated browser environment for maximum safety.
Zero Plaintext Logging
We never log, track, or even see the contents of your unencrypted data.
const key = await window.crypto.subtle.deriveKey(...)
const encrypted = await window.crypto.subtle.encrypt(...)
Protect Your Sensitive Information
From recovery phrases to developer secrets, keep everything private.

Frequently Asked Questions
Everything you need to know about our secure notes tool.
Are my notes uploaded to servers?
No. All notes are processed locally inside your browser and never uploaded anywhere.
Can SafeTools read my notes?
No. Your encrypted notes remain under your full control and we have no access to them.
Does Secure Notes work offline?
Yes. Most functionality works offline as a Progressive Web App (PWA).
Is encryption performed locally?
Yes. Encryption and decryption happen directly inside your browser using the Web Crypto API.
Can I use Secure Notes on mobile?
Yes. The tool is fully responsive and mobile-friendly across all major platforms.
What if I forget my password?
Unfortunately, there is no way to recover your note without the password. We prioritize security over convenience.
Secure Note Best Practices
Use Strong Passphrases
The security of your note depends entirely on the strength of your password. Use 12+ characters.
Clear Clipboard After Use
After copying your decrypted note, clear your clipboard to prevent other apps from seeing it.
Avoid Public Devices
Never decrypt sensitive notes on public computers or shared devices where keyloggers might exist.
Store Encrypted Blocks
Save your encrypted text in multiple safe locations. Without it, you cannot retrieve your data.
Security Architecture & Cryptography
For security professionals and curious users, here is exactly how we protect your data using the native Web Crypto API.
Key Derivation (PBKDF2)
Your password isn't used directly. We use PBKDF2 with HMAC-SHA256 and 100,000+ iterations to derive a secure 256-bit encryption key.
Authenticated Encryption
We use AES-GCM (Galois/Counter Mode), which provides both confidentiality and authenticity, ensuring the data hasn't been tampered with.
Initialization Vectors (IV)
Every encryption uses a unique, cryptographically strong random 96-bit IV, preventing pattern recognition in ciphertext.
Zero-Server State
No keying material, salt, or IVs are ever stored outside your device. You are the sole custodian of your digital vault.
How to Verify Our Claims
We believe in "Don't Trust, Verify". Here is how you can check our security yourself.
Network Audit
Open Browser DevTools (F12) -> Network tab. Perform an encryption. You will see 0 requests sent to any server.
Local-Only Logic
Turn off your Wi-Fi and use the tool. It works 100% offline, proving no server is needed for processing.
Code Transparency
Inspect the page source. All cryptographic logic is handled via the native window.crypto API.
