Does Hellotracks work when data/internet is off?

Hellotracks collects data without an internet connection, which will be analyzed and available as soon as you have a connection again. However, if you travel to a new country and do not have a data connection, the location services in your phone may be less accurate until you establish a network connection. Visiting a Wi-Fi hotspot just once can help the phone produce better location data.
