How It Works

  1. Client-side encryption

    Your file is encrypted in the browser using AES-256-GCM before upload.

  2. Key stays with you

    The decryption key is embedded in the URL fragment (#), which is never sent to our server.

  3. Recipient decrypts locally

    The file is decrypted entirely in the recipient's browser.

  4. Auto-delete

    Files are automatically deleted after expiry or first retrieval.
