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).

The viral app Tea, where women are invited to review the men in their lives, has just suffered a second data breach. According to the company, last week's breach included data that was two years old.

The images were being stored in a "legacy data system" containing information from more than two years ago, the company says.
