Well initially I giggled at the obvious flaws for a "girls only" app.
Then I read this...
"The app’s privacy policy is also a cause for concern, however. As one Twitter user pointed out, Giggle can collect a ton of personal information, including peoples’ images, location, preferences, and browsing data. Giggle is able to then share that information with third-party websites and services, including facial recognition providers, chat room providers, and marketers. It also collects sensitive information including peoples’ “sexual practices or sex life,” their criminal records, and their private health information.
Sex, Gender, Privacy? What a dilemma.
