Okay kiddo, have you ever been to a party before? Well, the Article 29 Working Party is kinda like a party, except it's not really a fun party.
It's actually a group of important people from different countries in Europe who work together to make sure that people's privacy is protected when they use the internet. They make rules and guidelines for companies like Facebook and Google to follow, so that they don't use your personal information in ways that you don't want them to.
The Article 29 Working Party is made up of people called "data protection authorities" from different countries. They all have a job to make sure that people's personal information is safe, so they get together and talk about how to do that better.
It's pretty cool that there are people like the Article 29 Working Party looking out for us and our privacy, don't you think?
