Executive summary / tl;dr

We’re committed to protecting your data, and since we’re proudly 🇪🇺 EU-based, also committed to taking the GDPR seriously.

We are curious about the regions and cities where our casual visitors come from, but not curious about who exactly they are, or how their neighborhood looks like. Our website and all the data that we collect and obtain reside on an IT infrastructure that is physically located in 🇩🇪 Germany. All of our web traffic analytics and newsletter management is handled directly and locally on our servers, not by third parties, like foreign companies.

When you subscribe to our newsletters, and later unsubscribe, we delete your data at most two weeks later. When you do business with us or become our customer, we keep related data on record only for as long and only to the extent mandated by tax and other laws. When you obtain a certificate after one of our events, we’ll store the related data for 5 years, so we can verify whether a disputed certificate was issued by us or not.

The only data that we are keeping until you request we delete it are your voluntary interactions with us (emails, survey answers, testimonials) – by default, we cherish this type of feedback like a souvenir.

We never sell your data to, or share it with, advertisers and marketeers.

Until the respective cases are settled, we do of course not delete evidence that we need to provide based on legal obligations, and to investigate, prevent, and stop crime, threats and harm. We also do not delete evidence of somebody trying to sabotage our business or infrastructure.

We fully respect your rights as stated in the GDPR. If you have any suggestions, questions, or requests, please feel free to contact our data controller (see below).

The following text describes all of this in more detail. To navigate quickly in this document, try the table of contents at the top.
