Let visitors opt out of analytics

Let visitors opt out of analytics with privatus.optOut(), the only flag the tracker stores, and exclude your own visits by browser, IP range or WordPress.

# Let visitors opt out of analytics

> Let visitors opt out of analytics with privatus.optOut(), the only flag the tracker stores, and exclude your own visits by browser, IP range or WordPress.

## For visitors

```js
privatus.optOut()      // stop sending hits from this browser
privatus.optIn()       // undo
privatus.isOptedOut()  // true or false
```

`optOut()` stores `privatus_optout=1` in `localStorage` on **your** domain.
It's the only thing the tracker ever writes to the device, and only
because the visitor asked for it, which makes it strictly necessary under
the ePrivacy Directive (Art. 5(3)). While it's set, the tracker sends
nothing: no pageviews, events, engagement, Vitals or clicks. Hits that
were waiting for a retry are dropped too.

The flag is per browser and per domain (subdomains have separate storage).
If storage is blocked, `optOut()` does nothing and `isOptedOut()` returns
`false`.

A ready-made button for your privacy page is in
[Opt-out snippet](/docs/privacy/opt-out). The WordPress plugin provides a
`[privatus_optout]` shortcode.

Browsers that send [Global Privacy Control](/docs/privacy/dnt-gpc) are
excluded automatically when the site honours GPC (the default).

## For you and your team

- Run `privatus.optOut()` once in the browser console on each of your
  sites and browsers.
- Or block your office or VPN IP ranges in
  [traffic rules](/docs/privacy/traffic-rules). The IP is checked in
  memory and never stored.
- WordPress: the plugin skips logged-in administrators by default.
