Lora, especially on regulated bands that are the most used ones, is designed for very small, very infrequent messages. It isn't suited for real-time chat (nevermind secure) and so I think you can't really make it work while respecting transmission regulations.
There are lora modules that work on the 2.4GHz ISM band but then you probably need to consider whether Bluetooth is not a simpler choice if range is not the no. 1 concern.

It is encrypted on private channels and direct messages.

I don't know from where your information's are from, but for sure not from reality. Voice encryption/scramble on Amateur-Band's is not allowed, everything else is ok.

It seems like you're saying voice encryption is not permitted, but data encryption is? This is not true in the US. Any encoding used for the purpose of "obscuring meaning" is not permitted on amateur frequencies. Even using code phrases like "the eagle has landed" is arguably not allowed. There are some narrow exceptions for things like satellite control codes, but nothing that applies to hobby mesh nets.
Here is the relevant Part 97 rule: https://www.ecfr.gov/current/title-47/part-97#p-97.113(a)(4)
> No amateur station shall transmit: [...] messages encoded for the purpose of obscuring their meaning, except as otherwise provided herein; obscene or indecent words or language; or false or deceptive messages, signals or identification.
So numbers stations fall under as otherwise provided?

I know what features it claims to have. The question is how well this can work on bands (US915, EU868) that very strictly limit the amount of time a device may transmit. IMHO you can't really have interactive chat on a mesh network over lora in those bands.
>I know what features it claims to have.
Yeah...no i don't think so.
>IMHO you can't really have interactive chat on a mesh network over lora in those bands.
Devices allow 10% Airtime on ISM here (EU) that's about 300 messages (with 255 characters) per hour, and yes interactive chat is possible with around 20 seconds of lag.
EDIT: I stop here, so much half knowledge that sounds educated but is in fact just wrong and TBH not even sure if i talk to a selfhosted AI.
Have a good Day.
