Plenty of Fish

In 2019, a security vulnerability was discovered by a security researcher that potentially exposed information users had set to privacy such as zip code and first name. The security researcher did say Plenty of Fish was responsive at getting this problem fixed, which is good to hear. This dating app also asks users to provide a whole lot of personal information when you sign up -- everything from our ethnicity and whether you smoke to if you own a vehicle and if your parents were married (seriously, they ask for that!). That's a whole lot of personal information you're giving a company that has a history of security vulnerabilities. Finally, Match Group owns Plenty of Fish and at least 45 other dating sites like Hinge, Tinder, and OKCupid. When you sign up with one of these dating sites, the Match Group privacy policy states they may share your personal information with any of the other Match Groups sites for what they say are non-commercial limited and critical purposes. That's a lot of personal data you might have thought only going to once place getting shared across multiple dating sites.
