Open-source, privacy oriented, outdoor fitness tracker... for Apple iOS.
(When I saw "Open-source, privacy oriented, outdoor fitness tracker", I thought it would be available for an open source platform, so I clicked. It being for a closed, all-your-data-are-belong-to-us platform wasn't expected. Maybe the comment saved some clicks.)
They own your device 100%. Of course they can access your data...

Incidentally, I'd love to have an open source, privacy-respecting nutrition tracker that works on open source desktops. (I find my laptop much, much faster than phone for recording this data, at least in the ad hoc way I'm doing it, including things like weights of every ingredient that goes into a dish.)
The most complete nutrient data for basic foods seems to be http://www.ncc.umn.edu/food-and-nutrient-database/ which you need to pay for, so I wonder how an open source implementation could work.
I use Cronometer daily which shows you the datasource for each food you add, and if it's not NCCDB (the one at the link above) then chances are it's not going to have much info. Yet that extra info is exactly why I'm using a nutrient tracker rather than just a calorie tracker.
In that realm, there is also GoldenCheetah:
