Everyone who uses “free” apps should understand that they are selling their privacy. Fitbit and other smart devices are no exception. Read this article on how Fitbit puts U.S. military in danger by revealing their locations on a publicly accessible website.

What about civilians using this device? A bad guy could learn your workout route and wait to do you harm. Think about the children who use these devices. No one is safe while wearing them.

If you ask us, we will tell you to throw them away. However, if you can’t live without electronics, find alternative devices that can help you with your workout without compromising your privacy. Just remember, if the device you are using requires you to connect to your phone, or the internet, you are under surveillance. This is because your data will be stored on a server somewhere to be sold, or in Fitbit’s case, put on public display.
