ELI5: Explain Like I'm 5

privacy

Privacy is about keeping things just for yourself and not letting anyone else know or see them. Just like how you can keep secret things in your room, you can keep certain things about yourself secret too. For example, you don't want anyone to know your address, phone number, what you look like, or what you and your friends talk about. That is why it's important to be careful when you're on the internet and to not share too much information with people you don't trust.
