Lots of eye-candy, but some privacy issues – Period Tracker ‎ Review

The app has some cool features, including cute themes, emotions and a handy graphing feature, but I have a lot of concerns about how my information, including medical information, is collected and shared. Their privacy policy seems to suggest that they collect and sell data, perhaps even my medical data? I deleted the app, but after creating an account with them I still worry abouy my privacy.
