Having experimented with this app for two weeks, I would like to offer my insights.

This app offers robust encryption, with the encryption key stored solely on your local device, ensuring that no middleman can access your information without the key.

You can chat securely without needing a VPN, which is particularly useful in regions where VPN usage is restricted. Even if you do use a VPN, the communication delay is practically unnoticeable.

I absolutely love this app. And I hope we can stack more than four codes. For me, this app is definitely a keeper.
