# Install Privatus Analytics with Google Tag Manager

> Load the Privatus Analytics tracker from a Google Tag Manager Custom HTML tag, set consent settings, send events from GTM triggers and avoid double counting.

If your site already loads tags through Google Tag Manager, you can load
Privatus Analytics from it. Adding the snippet directly to your pages is still more
reliable: GTM itself is blocked by many ad blockers.

## Custom HTML tag

1. In your container go to **Tags → New → Tag configuration → Custom HTML**.
2. Paste:

   ```html
   <script defer src="https://privatusanalytics.com/js/pa.js" data-site="pa_YOURSITEID"></script>
   ```

3. Trigger: **Initialization - All Pages** (or **All Pages**).
4. Save, preview, and **Submit** to publish.

GTM copies the `data-` attributes onto the script it inserts, so every
[attribute](/docs/tracker/attributes) works as usual.

## Consent settings

Privatus Analytics sets no cookies and reads nothing from the device, so in GTM's
**Consent settings** for the tag you can choose **No additional consent
required** if that matches your legal assessment. See
[Privacy & compliance](/docs/privacy).

## Sending events from GTM

Create more Custom HTML tags that call the JavaScript API, fired by your
GTM triggers:

```html
<script>
  window.privatus && privatus.track('Contact form', { form: {{Form ID}} });
</script>
```

`{{Form ID}}` here is a GTM variable. Only send values that contain no
personal data.

## Single-page apps

Don't fire the tag again on "History change" triggers. The tracker already
follows `history.pushState` navigations, so firing it twice double counts. See
[SPA double counting](/docs/troubleshooting/spa-double-counting).
