Tracker debug mode

Use tracker debug mode to log every hit to the console without sending it, send real hits from localhost, and check the /api/event request in your dev tools.

```html
<script defer src="https://privatusstats.com/js/pa.js" data-site="pa_YOURSITEID" data-modules="engage,auto,vitals,clicks,ask" data-debug="true"></script>
```

With `data-debug="true"` the tracker:

- **logs every hit** to the browser console as `[privatus] pageview {…}`,
  with the exact request body,
- **doesn't send anything**, so debugging never pollutes your data,
- runs on `localhost`, other local hosts and `file://`,
- logs why a hit wasn't sent (`[privatus] not sent: opted out`, `…:
  domain not in data-domains`, and so on).

## Sending from a local server

To send real hits while developing (for example, to test goals end to end
on a development site), use `data-allow-local="true"` instead.

The server only keeps hits whose hostname is the site's domain, one of its
additional domains or a subdomain of one. A site domain needs a dot and a
top-level part, so plain `localhost` and IP addresses such as `127.0.0.1`
can't be added and their hits are always dropped. Serve your local copy
under a hostname that can be a site domain, such as `myapp.local` or a
subdomain of your real domain, and create a separate site for it so test
hits stay out of your real data.

## Checking the network request

In the browser's developer tools, **Network** tab, filter for `event`.
Each hit is a `POST` to `/api/event` that gets a **202 Accepted**. See
[What the tracker sends](/docs/tracker/payload) for the body.

Sending from a local server#

To send real hits while developing (for example, to test goals end to end on a development site), use data-allow-local="true" instead.

The server only keeps hits whose hostname is the site's domain, one of its additional domains or a subdomain of one. A site domain needs a dot and a top-level part, so plain localhost and IP addresses such as 127.0.0.1 can't be added and their hits are always dropped. Serve your local copy under a hostname that can be a site domain, such as myapp.local or a subdomain of your real domain, and create a separate site for it so test hits stay out of your real data.

Checking the network request#

In the browser's developer tools, Network tab, filter for event. Each hit is a POST to /api/event that gets a 202 Accepted. See What the tracker sends for the body.
