  1. 1

    There is nowhere to send it

    ChatLens is a set of static files. There is no backend, no database, no accounts and no analytics script.

  2. 2

    Your browser enforces it

    The site ships a security policy (connect-src 'none') that makes the browser itself refuse any request this page tries to make. Look for the Content-Security-Policy header in your browser's developer tools.

  3. 3

    Test it offline

    Once this page has loaded, switch off Wi-Fi or turn on airplane mode, then drop in your file. The analysis works exactly the same.

  4. 4

    Watch the network

    Open developer tools, go to the Network tab and analyze a chat. No request appears.

  5. 5

    Nothing is kept

    No cookies and no saved data. The analysis lives in this tab's memory and is gone when you close or refresh it.
