Ha, perhaps Nuria’s quote should read:

Umm, it involves a cookie, which tracks whether you have previously
browsed the site. While I applaud the analytics team in using such a
privacy friendly method, I'm not sure its an entirely truthful
statement to say that it does not involve a cookie in which your
browser history can be tracked. The date you've visited previously
sounds like a part of your browser history to me.

To be clear, this is not meant to be a criticism. I think the approach
that is being taken is really great.

[Wikitech-l] Unique Devices data available on API

[Nuria Ruiz]

Hello!

The analytics team is happy to announce that the Unique Devices data is now
available to be queried programmatically via an API.

This means that getting the daily number of unique devices [1] for English
Wikipedia for the month of February 2016, for all sites (desktop and
mobile) is as easy as launching this query:

https://wikimedia.org/api/rest_v1/metrics/unique-devices/en.wikipedia.org/all-sites/daily/20160201/20160229

You can get started by taking a look at our docs:
https://wikitech.wikimedia.org/wiki/Analytics/Unique_Devices#Quick_Start

If you are not familiar with the Unique Devices data the main thing you
need to know is that
is a good proxy metric to measure Unique Users, more info below.

Since 2009, the Wikimedia Foundation used comScore to report data about
unique web visitors.  In January 2016, however, we decided to stop
reporting comScore numbers [2] because of certain limitations in the
methodology, these limitations translated into misreported mobile usage. We
are now ready to replace comscore numbers with the Unique Devices Dataset .
While unique devices does not equal unique visitors, it is a good proxy for
that metric, meaning that a major increase in the number of unique devices
is likely to come from an increase in distinct users. We understand that
counting uniques raises fairly big privacy concerns and we use a very
private conscious way to count unique devices, it does not include any
cookie by which your browser history can be tracked [3].
