About VanishNote.me

VanishNote.me provides a simple and secure way to share sensitive information through self-destructing notes. Once a note is created, a unique, unguessable link is generated. This link is the only way to access the note content.

How It Works - The Technology

  1. Note Creation & Encryption: When you submit a note, the content is immediately encrypted in your browser using AES-256-GCM before anything is sent to the server. The encryption key never leaves your browser.
  2. Temporary Storage: Only the encrypted ciphertext is stored on our server. We associate it with a randomly generated, unique identifier.
  3. Unique Link Generation: A unique URL is generated and presented to you. The decryption key is embedded in the URL fragment (#key=…), which is never sent to the server.

  4. Secure Retrieval & Decryption: When someone visits the unique link, the encrypted note data is sent to their browser. The decryption key from the URL fragment is used client-side to decrypt and display the content. The server never sees the plaintext.
  5. Self-Destruction Logic: Based on the parameters set during creation:
    • View Limit: Each successful view decrements an internal counter. Once the limit is reached, the encrypted data is permanently deleted.
    • Time Limit: Notes are automatically deleted after the expiration time you set, regardless of remaining view count.
    Once deleted, the data is irrecoverable.
  6. Minimal Logging: We do not log note content or associate IP addresses with specific notes after they are deleted.

Security & Privacy Focus

The entire process is designed with privacy and security as top priorities. By encrypting data client-side, using secure HTTPS for transmission, generating unique/unguessable links, and ensuring permanent deletion after expiry, we aim to provide a trustworthy platform for temporary information sharing.

Remember, the security of the note also depends on how you handle the unique link. Share it only with the intended recipient(s) through a secure channel.
