A FreedomBox is a small media computer, like a smartphone or laptop, which lets you keep your data and activities on the internet private. It works by connecting to a private network (meaning it's not connected to the internet or any other computers) and encrypting your data so that no one can see or access it. This means you can use the FreedomBox to store files, watch videos, chat with friends, and do a lot of other things without worrying about anyone else snooping or seeing what you're doing. It's like having your own private box online, where everything you do is safe and secure.
