Hi. When someone who comes up as a DNA Connection to you in Wikitree, say on ancestor's profile, that Wikitreer can look at your GEDmatch kit number and input it in GEDmatch to see how you are related. No personal info is displayed, just a way to see if you are related in case you are like the 10,000th person in the GEDmatch list and never get to it. Hope this helps. Also, once you upload the kits to Wikitree, it takes until the next morning for them to be displayed on your profile and relative's profiles, because they refresh everything once a day....
