Privacy focussed messenger
Guiding principles
- Everyone is blocked by default
- Can only message contacts where there is mutual agreement (i.e. both have added each other)
- Text only
- Transit over open protocols
- Mandatory encryption of communication stream
- Mandatory encryption of data (E2EE)
- No read receipts
- No way to know if someone has added/removed you from their contacts
- Messaging someone who hasn't added you to contacts = message silently deleted
Thoughts
- How to avoid a centralised server
- Can messages be delivered over Tor?
- How to deliver messages when the recipient isn't online
