View-once photos and expiring messages
Written by Julien Lenaz, lead developer of cruush.
View once
A photo sent in a message can be set to view once, so it does not stay in the chat.
Expiring messages
Messages can be set to expire so they do not sit in a conversation indefinitely.
The limit
Anyone can screenshot or photograph a screen. These options limit how long something stays in a chat. They do not guarantee no copy exists, so send only what you can live with.
When to use them
Use view once for photos you only want someone to see in the moment. Use expiring messages for conversations you do not want to sit around, such as details about where you are meeting.
If someone does not respect it
Block them from their profile. It takes effect immediately. Report them too, because a person reads every report.
