EncryptedNote encrypts your secret in the browser before it leaves your device, the server never sees the decryption key. Share passwords, API keys, or sensitive messages via a link that self-destructs after reading. No account needed from either side.

Built because most "private" sharing tools still encrypt on their servers โ€” meaning they hold the key. With EncryptedNote the key lives only in the URL fragment, which browsers never send to servers. We literally cannot read what you share.

XChaCha20-Poly1305 encryption. Hard delete on read. Custom expiry up to 30 days. No ads, no accounts, no data collection.

EncryptedNote features and specs

  • End-to-End Encryption
    EncryptedNote provides end-to-end encryption for notes, ensuring that only the sender and intended recipient can read the content, enhancing privacy and security.
  • No Account Required
    Users can create and share encrypted notes without needing to sign up or create an account, making it quick and convenient to use.
  • Self-Destructing Notes
    Notes can be set to automatically destroy themselves after being read, reducing the risk of sensitive information being accessed later by unauthorized parties.
  • Simple and Easy to Use
    The platform offers a straightforward, minimalist interface that makes it easy for anyone to create and share encrypted notes without technical knowledge.
  • Free to Use
    The service is available for free, making encrypted communication accessible to everyone without any financial barrier.

Possible disadvantages of EncryptedNote

  • Limited Features
    Compared to full-featured note-taking or messaging apps, EncryptedNote offers a very basic set of features focused solely on sharing encrypted text notes, lacking formatting, file attachments, or collaboration tools.
  • No Message History
    Since notes are typically destroyed after reading, there is no way to retrieve or review previously sent notes, which can be inconvenient if you need to reference past communications.
  • Trust in the Platform
    Users must trust that the service genuinely implements strong encryption and does not store or log note contents on their servers, which is difficult to independently verify without open-source code.
  • Link-Based Sharing Vulnerability
    Notes are shared via a URL link, which means if the link is intercepted during transmission (e.g., through insecure messaging channels), an unauthorized party could potentially access the note.
  • No Mobile App
    EncryptedNote is primarily a web-based service without dedicated mobile applications, which may be less convenient for users who prefer native app experiences on their devices.
