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.
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).
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.

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.
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.
