Perhaps this app is just for blockchain people? If it's another Internet of Coins app then that explains the vague website and the lack of things like privacy policies.
I do find it funny that they've added rules about linking to their website to their terms and conditions. As if they have any right to control the way people link to them.
Congratulations on your family being financially stable!
I use dedicated banking apps to "transfer value" because they're easy to use, secure, developed by a party I trust, and have legal protection from by law.
I get it, shittier countries don't have easy (or any) access to good banks. I still maintain that these value transfers should be done through their separate, secured and verified apps, no matter the transaction mechanism. Send money in the form of NFTs if that's what you want, but do so through an app that's built to do so securely, not some random NodeJS chat app.
Hell, because of the peer to peer nature of this thing, people's contacts can easily be tracked by the government. Good luck convincing the tax auditor that you didn't in fact send your parents a bunch of money when they have the connection logs to show it, enjoy paying unscrupulous taxes to your oppressive government. I'll take my alternative payment system offline or through a trusted third party server, thank you very much.
It's also a better and more correct way to use bitcoin just as money, and not as some kind of ownership token, which plagues the web3 scene. The core purpose of money is to be interoperable, to allow all kinds of goods and services to be traded in a common unit and payment network.
