How your numbers stay on your device

kmra calculators do all the maths in your browser, so what you type stays with you.

  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 you type is worked out in your device's memory, right in the page.

  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 what you type 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.
