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.

⏰ 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
