This site contains a widget that uses the true random number generator of random.org to create a random number. By default, it simulates the rolling of a dice.
The numbers generated by this widget come from RANDOM.ORG's true random number generator.
I found out that the widget of random.org uses Google Analytics, which is illegal to use in Europe. It is also incompatible with the way I understand privacy focused sites shall work. Therefore, I decided that until I find a better solution, I will take the widget offline.
