Right, it seems they only use tracking to display ads for their app/website. But then I wonder why they would be listed as Adsquare partner for their proximity targeting technology? Geo-IP can be used in some cases (weather, events), but is in other cases not precise enough for real proximity targeting. Also, strangely, all Adsquare listed proximity targeting partners are apps or companies that have direct access to their users GPS position.
