MzFit: The Privacy Focused YouTube Fitness App

MzFit does not track personally identifiable information for you. This means that we:

• Don't use features of YouTube that require logging in (like editing playlists or leaving comments).
• Don't ask for your email address or phone number.

When you watch a video with YouTube, they will set a cookie that may allow them to track your activities, but the cookie will be separate from what you view via the YouTube app or web browser.

If you use an anonymizing proxy service such as Apple's Private Relay service, it is very difficult for anyone, whether it be MzFit or YouTube, to tie your workout activities to your real location or identity, unless you launch the YouTube app or web site directly.
