Looks interesting! I had a few questions:
- I notice in the demonstration on your website that the user scans the QR code on your camera to pair with their Android/iOS device. Does this automatically perform out-of-band key verification? (Sort of similar to how SimpleX Chat works when adding contacts.) If not, would you consider adding this feature to defend against MITM attacks?
- Are there any intentions develop Windows, Mac, or Linux apps in the future?
