Encrypted self-destructing messages. Your password never leaves your browser.
Encrypting in your browser...
PrivNote is a self-destructing encrypted message service that lets you send sensitive information that disappears after being read. Our free encrypted note service uses AES-256-GCM encryption with zero-knowledge architecture — your password never leaves your browser. Whether you're sharing passwords, confidential instructions, private links, or sensitive personal information, PrivNote ensures your message is seen only by its intended recipient and then permanently destroyed.
The encryption happens entirely in your browser before the note is sent. Your plaintext message and password are encrypted client-side using PBKDF2-derived AES-256-GCM keys. Only the encrypted ciphertext is transmitted to our servers. Even if our servers were compromised, your messages remain unreadable. You can optionally set an expiry time (1 hour, 24 hours, 7 days, or 30 days) after which the note is automatically deleted even if unread.
Key features include: military-grade AES-256-GCM encryption with PBKDF2 key derivation (600,000 iterations), zero-knowledge password handling, self-destruct after first read, optional time-based expiry, anonymous usage with no registration, and clean one-click copy of shareable links. From security-conscious professionals to everyday users sharing sensitive information, PrivNote provides enterprise-grade secure communication.
Tip: For maximum security, share the password through a different channel than the note link (e.g., link via email, password via SMS). This ensures that even if one channel is compromised, your message stays secure.
A secure messaging service that encrypts your notes in-browser and destroys them after they're read.
Yes, completely free with no limits, subscriptions, or hidden fees.
No. Create and read encrypted notes instantly without any account.
Yes. AES-256-GCM encryption with PBKDF2 key derivation (600K iterations). Your password never reaches our servers.
The note is permanently deleted from our servers. It cannot be recovered by anyone, including us.
Yes, choose from 1 hour, 24 hours, 7 days, or 30 days. The note auto-deletes even if unread.
No, but it's recommended for sensitive information. Without a password, the encrypted note can still be read by anyone with the link.
Once you create a note and the link is generated, that is the only way to access it. Open the link in a private/incognito window to test it.
AES-256-GCM (Advanced Encryption Standard 256-bit) with PBKDF2 key derivation using SHA-256 and 600,000 iterations.
Chrome, Firefox, Safari, Edge, and Opera. Requires Web Crypto API support.
Yes, fully responsive for smartphones and tablets.
No. Once read, the note is permanently deleted. This is by design for security.
Sending sensitive information online carries risk. Emails are stored indefinitely, chat logs persist, and data breaches expose everything. PrivNote solves this with zero-knowledge encrypted notes that self-destruct after reading.
A browser-based encrypted messaging service where your password never leaves your device. Messages are encrypted with AES-256-GCM before transmission and permanently deleted after first read.
