Analytics opt-out button snippet

Copy a ready-made opt-out button for your privacy policy page that lets visitors stop being counted by Privatus Analytics in their browser, and how it works.

以 Markdown 檢視

Visitors can opt out of being counted in their browser. Put this on your privacy policy page. It works wherever the tracker is installed.

html 
<p id="privatus-optout-status">Checking…</p>
<button type="button" id="privatus-optout-button" hidden>Change</button>

<script>
  (function () {
    var status = document.getElementById('privatus-optout-status');
    var button = document.getElementById('privatus-optout-button');
    function render() {
      if (!window.privatus || !privatus.isOptedOut) {
        status.textContent = 'Analytics isn’t running in this browser, so your visits aren’t counted.';
        return;
      }
      var out = privatus.isOptedOut();
      status.textContent = out
        ? 'Your visits to this site are not counted.'
        : 'Your visits are counted anonymously, without cookies.';
      button.textContent = out ? 'Count my visits again' : 'Don’t count my visits';
      button.hidden = false;
    }
    button.addEventListener('click', function () {
      privatus.isOptedOut() ? privatus.optIn() : privatus.optOut();
      render();
    });
    window.addEventListener('load', render);
  })();
</script>
  • The choice is stored as privatus_optout=1 in localStorage on your domain, only after the visitor clicks. That's the only thing Privatus Analytics ever stores in a browser.
  • It applies to this browser and this domain. Subdomains (shop., blog.) have their own storage, so add the button there too, or on each domain you use.
  • Clearing site data removes the choice.
  • If the tracker is blocked (for example by an extension), the snippet says so and hides the button: nothing is counted in that browser anyway.

WordPress: use the [privatus_optout] shortcode instead. The tracker API behind this is described in Opt-out.
