  Digital services like ride sharing rely heavily on personal data as
individuals have to disclose personal information in order to gain access to
the market and exchange their information with other participants; yet, the
service provider usually gives little to no information regarding the privacy
status of the disclosed information though privacy concerns are a decisive
factor for individuals to (not) use these services. We analyzed how popular
ride sharing services handle user privacy to assess the current state of
practice. The results show that services include a varying set of personal data
and offer limited privacy-related features.
