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.

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).

Hackers have breached the Tea app, which recently went viral as a place for women to safely talk about men, and tens of thousands of women’s selfies and photo IDs have now seemingly been leaked online.
