Summary:

• **What is a Data Firehose?** A "data firehose" is when companies collect huge amounts of personal information about you very quickly, like a fire hose spraying water everywhere. This information includes things like where you go, what you buy, and what websites you visit, and companies store all of this data about millions of people.

• **Why Should You Care?** Even though companies say they use this data to help you, it can be used in ways that aren't fair or safe, like selling your information to others or using it to manipulate what you see. Understanding how much data is being collected about you helps you make better choices about what information you share online.
