For what it's worth, I subscribed to Ultra about an hour ago and DDG hasn't picked up any additional tracking attempts since then. I think it may be limited entirely to Google's ad service for the free, ad-supported tier and maybe crash diagnostics that the app gives you the option of enabling or disabling.
I think that the lack of further attempts backs up what lj shared a bit ago in the Discord. That's still a hell of a lot of tracking for folks who can't or don't want to pay, though.
Sure would be cool if this kind of information was provided outside of a proprietary service that not only requires a login but also you to join a specific server just to then have this be hidden by 1,500 random messages that you don't care about. Shame there is no such place.
Basically all tracking is done by Google ads. It checks at start up if you have purchased ad free or not. If purchased, launch app without ad library, else launch with ads.
It has to be in the code because (according to the dev) Google is cracking down on similar apps, ie a pro version and a free version. So ad library has to be included, and it just won't use it if you pay for pro
FWIW that page is a bit deceptive , it's not saying it's collecting all of that data. The only info on that page is "146 tracking attempts from Google", which makes sense if it has Google ads.
Please note that the long list of things collected is what Google is known to collect, not necessarily that these are the things being collected. If you click on any other app that is also with Google trackers (practically every app listed on this page), you will find that the stuff listed are the same.
I would really love to know what ads are targeting low battery levels. Chargers and battery packs obviously. But I wonder what else being at 5% tells you about a person 😅
