Tea's investigation of the incident found that app users' direct messages had been breached, along with some of their photos. "Out of an abundance of caution, we have taken the affected system offline," Tea said in a statement to CBS MoneyWatch.

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).

A data breach exposed photos and ID cards of women who signed up for a fast-growing app for women to share details of men they might date.
