Health and fitness apps track a lot of data—your location, heart rate, sleep patterns, weight, workout habits, and sometimes medical history. This information can be valuable for your own health goals, but it also gets shared with advertisers, data brokers, and sometimes third-party companies you've never heard of. Understanding what these apps collect, where that data goes, and what you can actually control helps you make choices that match your comfort level.
The articles here cover practical questions: what information different types of apps typically gather, how to read privacy policies without getting lost in legal language, which settings let you limit what gets tracked, and how to spot red flags when an app asks for more permissions than it needs. You'll also learn what your rights are if you want to delete your data or switch to a different app.
