Online and max users counters in this extension

How can i activate such reporting for my extension?

• You need to write me an email at dnbard[at]gmail.com with id of your extension. It is written in package.json in name field
• After that you will get an token that should be sent once a hour from every user of your extension
• You need to sent a GET request to http://brackets-online.herokuapp.com/tick/<extension token here>
• You can use online tracking client example

Multiple requests from same user in one hour period will be counted only once.

Note: I'm not store any user related information.
