Re: [Foundation-l] Fw: Strike against the collection of personal data through edit links
I put together a short explanation of how clicktracking works, what data it stores and why we use it. I'll work with Oliver to make sure this is also captured in the AFT5 FAQ. Feel free to contact me off-list if you have specific questions that I haven't answered here. Dario * What is clicktracking? Clicktracking is an extension developed by the Wikimedia Foundation during the Usability initiative [1]. It has been used since then to test a number of features or to run some small-scale usability experiments. * How does it work? The extension collects click-through data (e.g. it counts clicks on a call to action after posting article feedback) that is typically not stored in the database. An example of the data collected by this extension can be found here [2] * Why do we use clicktracking in AFT? We use clicktracking to measure aggregate click-through/completion rates as part of our analysis of AFT [3]. We randomly assign users to different buckets or experimental conditions (e.g. a specific AFT design) or to a control group. This allows us to measure how each condition performs with respect to each other. For example, we want to know how a specific AFT design affects editing behavior or how many people who see the AFT widget at a specific placement take a call-to-action. The two main reasons why we use the clicktracking extension for this purpose are (1) to capture bucket information, which is not stored in the database, and (2) to measure drop-off rates for specific funnels (e.g how many users browse away after clicking on a button). As such, the extension is used to count events for groups of users and it's not designed to track individuals, let alone store personally identifiable information. For example, it does NOT store user IDs or usernames for registered editors and it assigns and stores randomly generated tokens for every user. * Why these ugly URLs when I click on a section link? Clicktracking is usually implemented via javascript and session cookies, but in some cases it's easier to just pass a URL parameter when a form is submitted. We appreciate that the AFT5 implementation of clicktracking is not very elegant and we will disable it as soon as we've collected the data needed for the analysis. * What is the status of data collected via clicktracking? Data collected via the clicktracking extension is subject to the privacy policy [4] and as such it's not publicly released, unless in a fully anonymized or aggregate form.

Re: [Foundation-l] Fw: Strike against the collection of personal data through edit links
I'm not sure why this couldn't be done if that were all that is being measured. I suspect there's other behaviors being tracked. As I said, I'm not the person who knows most about this, so you have to take what I am saying with a grain of salt.

Those weird URLs are part of a clicktracking process. It's a test to see how people go about editing the page *most often* (by section, or by edit tab) and further to see how effective various calls-to-action (such as those given by Article Feedback) are. The longevity of the data isn't something I can comment to but I'd be surprised if it lasted even 3 months. I do not know if there are identity markers connected to them but I wouldn't be surprised. To that end, the data is only useful in roll-ups, and wouldn't be something published anywhere except in aggregate.
