You probably realize this, but just in case you didn't, every time you contact a web server, it stores information about your request. This disclosure describes the information stored by my web server in relation to this script, and what I do with it.
The following information is current as of June 23, 2016.
Every time a file is retrieved from my site, the web server records certain data in its log, including: the file requested; the date and time; the referring page (if applicable); the browser identification string sent with your request; any cookies set by this site and returned with your request; and the IP address associated with your connection to my web server. The following files related to this script are retrieved from my site: screen shots of this script in action, the PDF version of that page, the updater script used in version 1.6.0 and earlier, and the icon used for OpenUserJS.org and Greasy Fork.
(A browser identification string looks more or less like this: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:47.0) Gecko/20100101 Firefox/47.0. As you can see, it usually shows your browser and operating system. In some cases, it could list add-ons as well. You can view some of the data your browser provides to web sites on this page: Browser Tests 2016.)
After installation, and during day-to-day use of the script, no information is sent to my web site. The next time you are likely to interact with my web site is when you update the script, or view updated images on a page describing the script. (When checking on the availability of updates, the updater requests information from userscripts-mirror.org or openuserjs.org or greasyfork.org, not from my server.)
Currently, this log information is not used for anything other than to try to estimate the number of installations by users of Firefox and Chrome. However, I am interested in learning where the script has been installed globally. This would involve submitting the IP addresses to an analytics site/service that researches their location down to the country or region. I have no interest in identifying individuals or companies, and in most cases that would not be possible based solely on an IP address.
Currently, the log information is stored indefinitely. However, I eventually will start to discard older information over time.
My web server may set cookies depending on the files retrieved. I am not aware that these are used for anything, other than to gather statistics about site usage.
I use Google Analytics to measure the usage of some pages on the site (such as this one). I really have no idea what Google does with the data, other than prepare charts and graphs for me.
This site currently does not implement "do not track."
