I understand what you mean.
You can build it yourself, the GitHub repository is on the Wiki, along with a step by step process on how to build it.

In regards to your second point.
I've designed it to be completely offline (the taproot wallet), but for the "group" functionalities you need to be connected to the internet.
All the communication with the server for this "group" functionalities are AES256 encrypted, more over, all the data in the server is encrypted by the user's internal PrivateKeys, so there is no way to access any of the information hosted on the servers.


I haven't been able to finish the Wiki yet, but all of this will be explained in detail.

But you can now test all the functionalities (after you build it from the "source" :-) ) on testnet.

In addition I'll be publishing extensive automated test results once I've finish created and running them.

At this point I don't think I can "guarantee" more than these.
You have to test it for yourself.

Does it make sense what i'm saying?

Thanks for your question.
