SecretNote - Share private notes that self-destruct
Send encrypted messages that automatically self-destruct after being read. SecretNote is a free web-based service that lets you share confidential notes and private messages. Generate a secret link to send your encrypted note securely - your sensitive information remains completely private and protected.
Why should you use SecretNote to share private messages?
Your private note is encrypted in the browser and disappears after it is read.
Zero-Knowledge Architecture
Every private note, secret note, or encrypted message is secured with AES-256 directly in your browser. We never see your confidential content - not even for a second. You are the only one who can access your secret.
Self-Destructing Messages
When your confidential note or message is viewed, it's permanently deleted. Even if a link is intercepted later, the encrypted data is already gone. Sharing a secret note means true peace of mind.
Completely Anonymous
No accounts, no emails, no tracking - SecretNote allows you to share a private note or encrypted message without ever revealing your identity.

Frequently asked questions
Quick answers about sharing private data safely
Use SecretNote to create a one-time encrypted note instead of plain email or chat. Share the link separately, set an expiration time, and enable burn-after-reading to reduce exposure.
No. Email is not designed for secret delivery and messages can be forwarded, indexed, or stored for years. Use SecretNote instead so credentials are encrypted and automatically destroyed after viewing.
Ideally, never. If temporary access is unavoidable, rotate the password immediately after use and share it only through a self-destructing encrypted note created with SecretNote.
No. Notes sent via SecretNote with burn-after-reading are permanently deleted after opening and cannot be restored.
Avoid passwords, private keys, recovery codes, identity numbers, and unredacted personal records in normal chats. Use SecretNote for this type of data so it does not remain in chat history indefinitely.
For sensitive data, yes. Attachments in email are often duplicated across inboxes and backups, while files and messages shared through SecretNote can be encrypted and configured to disappear.
You can choose the auto-destruction time for unviewed notes in Options before creating the link. The default is 3 days, and you can set shorter or longer lifetimes there anytime. Once a note is viewed, it is destroyed regardless of the lifetime option. Create your note at SecretNote.
