How NoteHash Works

Simple, secure, and completely anonymous note sharing

Length Modes

Normal Mode (No Storage)

Your note is compressed and placed directly in the URL fragment (the part after #). We never see or store your content - it exists only in the link itself.

How it works
  1. You type your note (up to 1,000 characters)
  2. We compress it using gzip for efficiency
  3. The compressed data is encoded into the URL
  4. Share the link - the recipient's browser decodes it
Privacy: Since the note is in the fragment (#), it never reaches our servers. Your browser handles everything locally.

Short Link Mode (Expires)
Coming Soon

Keeps your URL short by storing a small encrypted blob server-side with automatic expiration. The link contains only a short key.

TTL Options
  • 1 hour - Perfect for quick shares
  • 24 hours - Daily communications
  • 7 days (Pro) - Weekly updates
  • 30 days (Pro) - Monthly reports
  • Pin forever (Pro) - Permanent storage
Auto-deletion: Notes are automatically deleted after expiration. No manual cleanup needed.

Security Modes

Normal Security

No password required. Anyone with the link can read the note. Perfect for non-sensitive information.

Warning: Only use this for information you're comfortable sharing publicly.

Password Protection

End-to-end encryption using AES-GCM with PBKDF2 key derivation. Your password never leaves your browser.

Technical Details
  • AES-256-GCM encryption
  • PBKDF2 with 120,000 iterations
  • Random salt and IV for each note
  • Authentication tag prevents tampering
Important: If you lose the password, the note cannot be recovered. We have zero knowledge of your password or content.

Privacy & Security

Zero-Knowledge Architecture

No Analytics on Fragments

URL fragments (#) are never sent to servers, ensuring complete privacy

Client-Side Encryption

All encryption happens in your browser before any data leaves your device

No Recovery Backdoors

We cannot decrypt your notes, even if legally compelled
