Can we have some clarification on what "Usage Data" the app collects and shares with advertisers?

LJ was very adamant about not collecting or keeping any user data under the reddit regime. I’m happy giving him the benefit of the doubt here.
The point is we don’t formally know.
The dev has stated that the tracking is disabled if ads are disabled, and other users have confirmed that via duckduckgo.
Hope this works but here’s what ddg is showing me was blocked. Only Google attempted to track and it was only once before I purchased ultra.
What’s that app you’re using to see that info?
