We can't see your data. Not won't — can't.
There is no Arth server holding your money. Your accounts, your keys and all the arithmetic live in an encrypted vault on this device, so there is nothing for us to read, sell, or lose. Connect your own AI key and those questions go straight to that provider, on your account. Still never through us.
