How your music practice stays on your device

kmra music tools make every sound and do all the listening in your browser, so nothing leaves your device.

  1. 1
    You open a tool

    Your browser downloads the tool's code once, like any web page.

  2. 2
    Your browser does the work

    What the microphone hears is analysed in your device's memory and never recorded.

  3. 3
    You get the result

    Results appear as you type, ready to copy or save.

Blocked by design

Every kmra site sends a security policy that stops the page from contacting any other server. Even if there were a bug, your browser would refuse to send the sound anywhere.

Check it yourself

  1. Open your browser's developer tools.
  2. Choose the Network tab.
  3. Use any tool. Nothing is sent while it works.
