Signal’s private texting software now includes Stories

These individuals might include everyone in your contacts who use the app, as well as anybody with whom you’ve had a one-on-one discussion or whose message request you’ve accepted, even if you’ve never added them. You may also build unique stories that are exclusively viewable to certain visitors, such as coworkers or those who share your interests. You may also share your experiences with existing groups. Just keep in mind that everyone in that group, even people you’ve never engaged with in individual conversations, will be able to view anything you discuss.
