In order to investigate the possible causes and courses of chronic diseases, it may be of interest to know, for example, what the outside temperature was, the humidity degree or level of air pollution. 

Meteorological institutions and governmental agencies open up their data to the public. Our data analysts then interpret this data and link it to the ‘location' data of your smartphone.
This way we can see where you were when you typed and what, for example, what the weather conditions were. 

It’s interesting to see if these datasets provide insights that can help you with advice. 

Not to worry, as we do this in a radius of more than 1 metric kilo-meter and once you’ve provided consent. We do not want to know exactly where you were but accurate enough to be able to say something about, for instance the weather in that area.
