## Opting Out

If you need to disable Optimizely Performance Edge on a page, but you are unable to remove the Optimizely Performance Edge tag, the Edge Decider will obey the `optimizelyOptOut` cookie on your cookie domain. Make sure that you set the  `optimizelyOptOut` cookie prior to your Optimizely Performance Edge tag so that the cookie gets sent to the Edge Decider.

**What does opting out mean?**

- The user will not get bucketed into an experiment.
- The user will not see any variation changes.
- Project JS will not run on the page.
- The user will not be tracked.
- The user will remain opted out (i.e., all of the above will apply) anywhere that Optimizely Performance Edge is running on the same domain.

You can also set the `optimizelyOptOut` cookie with the `optimizely_opt_out=true` query parameter, like so: `www.yoursite.com/?optimizely_opt_out=true`.

## Code sample

```html
<!-- 1. Set the opt out cookie on your cookie domain -->
<script>
  var maxAge = 6 * 30 * 24 * 60 * 60; // 6 months
  var yourCookieDomain = '.example.optimizely.com';
  document.cookie = `optimizelyOptOut=true; path=/; domain=${yourCookieDomain}; max-age=${maxAge}`;  
</script>

<!-- 2. Add the Performance Edge script tag after the cookie-setting logic -->
<script src="/edge-client/v1/<account_id>/<project_id>"></script>
```

## Opt In

To opt in, delete the `optimizelyOptOut` cookie on the cookie domain prior to the Performance Edge tag.
