Tea, a provocative dating app designed to let women anonymously ask or warn each other about men they’d encountered, rocketed to the top spot on the U.S. Apple App Store this week. On Friday, the company behind the app confirmed it had been hacked: Thousands of images, including selfies, were leaked online.

Tea, a dating safety app which allows women to anonymously give men red or green "flags," says it had more than 70,000 photos stolen in a data breach.

Its full name is Tea Dating Advice, and the central idea is a women-only app that gives those who are dating the ability to access background checks on men. This includes whether they have a criminal record (or if they're sex offenders), as well as reverse image searching to identify catfishing (assuming a false identity online).
