After opening up its platform to encourage worldwide exploring on Android, anonymous sharing app Secret has announced a new way for users to tailor their experience around private groups. The company announced the new feature, called “Dens,” on Monday via blog post. With a den, users will be able to keep their anonymous secrets to the confines of a particular workplace or school. “Our invite-only pilot of Dens follows an experiment at Secret HQ, where the 16 of us can share anything and everything we want — just with our team,” the blog post said. “After enjoying our inside jokes, updates and secrets in our Den over the last month, we’re confident that any company will love having one of its own.”
