Personally Identifable Information (PII)

Commenting on this blog requires a valid e-mail-address (technically it requires a name, too, but I don’t care how you call yourself). If you use an obviously fake e-mail-address I will probably not publish your comment.  I will delete your comments, and the associated e-mail-address, on request (best sent via the same e-mail-address) . I will not share your e-mail-address or other PII with third parties.

I will not attempt to get  PII that is not needed for commenting, and I would ask you kindly not to include information you do not want to be publicly exposed in your comments. However I use a web tracking software to collect anonymous information about pageviews, visits etc. This includes a cookie with an id that is specific to your browser or device  and is used to aggregate individual pageviews into sessions and information about recurring visits. I will not connect this information with names, e-mail-addresses or any other kind of PII.

Google Analytics

This page uses Google Analytics (GA). Since in these parts IP addresses are considered PII, GA ist set to anonymize IP addresses by removing the last tuple (in IPv4 addresses) or the last 80 bytes (in IPv6 addresses). If you want to opt-out from being tracked I recommend you use the official Browser Add-On (which will opt you all for all websites, not just this one).

The browser add-on will still load a stub of the GA code simply to avoid inline calls to Google Analytics methods from producing javascript errors. However no tracking calls will be made to the Google Analytics servers (you can check this in the “network” tab of your browser’s development tools or via a proxy that records network traffic).  You might also choose to use a tool like Ghostery (not a recommendation, just pointing out an alternative).

I do not use any of the GA features (“Display Features”, “UserID” and others) that connect (albeit anonymized) user data from other sources (Google Display Network, backend data of my own etc.) with tracking information.

Google Tag Manager

This page implements the Google Tag Manager (GTM). GTM is not a tracking tool (although it can be used to deploy tracking tools) and, by itself, does not collect any data, personally identifiable or otherwise. GTM creates a “data layer” (a set of name/value pairs) that might be used to  pass on information to a tracking system. On this website the data layer originates from within the CMS and does not contain information about visitors (instead it will hold information about the blog category, author, title etc.) . You can inspect the data layer by either looking at the sites source code or by opening the javascript console in your browsers development tools and typing “dataLayer” (camel cased / case sensitive).

Server Logs

The web server maintains a logfile that stores information which Url has been called at what time with what kind of browser, the referring page and the http status. While IP addresses are logged, too, they are truncated before they are written to the file so they no longer constitute PII.

Comment Policy

I’m all for freedom of speech but I won’t take risks on your behalf. So if by my own judgement your comments violate the law of my home country (Germany) I will not publish them. I will not publish obvious spam. You are however invited to disagree with me and to start discussions. Moderation in your language is suggested but not required, at times I am needlessly passionate myself.
