Care19, a contact tracing app used by North and South Dakota, violates its own privacy policy. Notably, the creator of the app, ProudCrowd, made sure that location data from the app is shared with Foursquare, although it claims it’s not used for commercial purposes. It’s a violation of its privacy policy because users are told their location data is private:
This location data is private to you and is stored securely on ProudCrowd, LLC servers. It will not be shared with anyone including government entities or third parties, unless you consent or ProudCrowd is compelled under federal regulations.
