Sharing

Happy lets you share sessions with other Happy users, either privately via friend invite or via public links.

​

Friends

Before you can share sessions privately, you need to add friends:

1. Go to the Friends tab in the app
2. Tap Search to find users by username
3. Send a friend request — the other user will see it in their pending requests
4. Once accepted, you can share sessions with each other

​

Private sharing

Share a session directly with a friend:

1. Open the session you want to share
2. Tap the share icon in the top bar
3. Select a friend from the list
4. Choose an access level:
   • View — Can read messages but not send
   • Edit — Can read and send messages
   • Admin — Full control including sharing with others

The shared session is end-to-end encrypted. Your friend receives the session encryption key through a secure NaCl Box key exchange — the server cannot read the shared content. Shared sessions sync in real time: messages, git status, and voice chat are broadcast to all participants.

​

Public share links

Create a link that anyone can use to view a session:

1. Open the session
2. Tap share > Create public link
3. Configure options:
   • Expiration — How long the link is valid
   • Use limit — Maximum number of viewers
4. Copy and send the link

Public links use token-derived encryption keys — the link itself contains the decryption key, so anyone with the link can view the session.
