By default, Ackee won't track personal information like device and browser info. To enable detailed tracking, pass the data-ackee-opts to the script tag:

<script async src="https://ackee.domain.com/tracker.js" data-ackee-server="https://ackee.domain.com" data-ackee-domain-id="217118b9-1843-4462-82ba-2e0acd189b91" data-ackee-opts='{ "ignoreLocalhost": true, "detailed": true }'></script>

You should now be able to see detailed stats.

See Ackee's docs for more information.
