Safer Internet Day (SID) 2025 was celebrated worldwide on February 11. Together with the partners of the Safer Internet DE association, klicksafe is implementing the motto "No likes for lies! Recognize extremism, populism and deepfakes online" with a wide range of activities. With our digital school lesson, we were able to educate over 31,000 schoolchildren across Germany about right-wing extremist propaganda and disinformation online. In Berlin, we organized a dialogue panel with pupils, experts and Federal Minister for Family Affairs Lisa Paus. A big thank you to everyone who helped make this year's SID such a success. The SID may be over, but there are still many more activities throughout February. More than 300 campaigns were registered with klicksafe for the SID. In our article you will get impressions and an overview of this special day.
