What Your Fitness Tracker Knows About You

A fitness tracker on your wrist counts every step and heartbeat all day. AI inside it can spot patterns — but it can also share that data with companies.

Some examples

• Tracker notices your heart rate jumped while sitting still — interesting clue
• It can tell when you slept badly and suggest you rest
• It shares some of that with the watch maker
• It is not a doctor — never diagnose yourself with it

Try it!

What is one thing a tracker should NOT share with anyone?

Practice this safely

Try this with a low-stakes example and a trusted adult nearby. The goal is to notice how AI talks about wearable, not to let it make the decision for you.

1. 1Ask AI to explain wearable in plain language, then underline anything that sounds uncertain or too broad.
2. 2Give it one detail from "What Your Fitness Tracker Knows About You" and ask for two possible next steps plus one reason each step might be wrong.
3. 3Check heart rate against a trusted source, teacher, adult, expert, or original document before you use it.
