Privacy by default
We collect data through a snippet that is installed on your website. This snippet only collects data on the pages you've specified as being tracked. Our snippet (anonymously) tracks user experiences using Javascript.
For this we use localStorage by default, to get more reliable unique versus returning data. Users can disable usage of local- & sessionStorage though. We will then fall back to other methods where no local- & sessionStorage is used.
Additionally, while we are tracking query string information, we only collect the keys and not the values. That's because keys (usually, and should not) contain personal data. It is likely that query string values are going to contain personal personally identifiable information (PII). As a result, we won't collect them by default. But you can change this behaviour per query string key. Be sure to use our ability to anonymize such data.
