About PvtNote

A modern, secure platform for sharing encrypted notes with automatic expiration.

🔒 Security First

Every note is encrypted using industry-standard AES-256-GCM encryption before it leaves your browser. We use client-side encryption, which means your data is protected even from us.

  • • End-to-end encryption
  • • Zero-knowledge architecture
  • • Secure key derivation (PBKDF2)
  • • CSRF protection
  • • Rate limiting

⏰ Auto-Expiring

Notes automatically delete themselves after the specified time period. Choose from 1 hour to 1 week, or enable "burn after reading" for maximum security.

  • • Flexible expiration times
  • • Burn after reading option
  • • Automatic cleanup
  • • No permanent storage
