I'm amadeus, a german student who is currently writing his research paper. To make this really blunt topic a little bit more interesting (and to narrow it down - data security is a huge topic) I decided to specialize in navigation and motorbikes - and I guess you know now why I am here: Because you are the specialists in this topic.
I don't want to go into too much details: The whole questionaire is about what personal data you would offer to an app. I can't tell more because I'm afraid to lead you in any direction.
So if you have a spare two minutes I would be happy to get your help - it will save me a lot of trouble.
