on the top of the screen you'll see an orange bar. click on community and select spark page from the menu that pops up. on the next screen click on edit my spark page. at the top on the right hand side you'll see a lot of boxes to check. share my food tracker is about 2/3 of the way down this list. make sure the box is not checked, scroll all the way down to the bottom of the page and click save then you'll be good to go.
Does anybody know how to make my nutrition tracker info private? I've had several people message me with comments about what I've been eating. While I always welcome the feedback, I'm not at a place emotionally to have that be public information
