Rela, a popular Chinese dating app for lesbians set up in 2012, has been shut down along with its Weibo account.
The service was temporarily suspended due to an "important adjustment in service," Rela told users on its WeChat app account, according to Reuters.
"Rela has always been with you and please await its return!" it added, but gave no details of why it was suspending service.
The app currently has around 5 million registered users, a cached version of its entry on Apple's iTunes site shows.
Neither Rela nor Chinese authorities have commented on the shut down.
Last month, Zank, another gay Chinese dating app, was shut down by China’s regulator due to pornographic content, according to its Weibo account.
