I tried Termux and found the application files I wanted to rsync aren't visible in Termux, except maybe by rooting the phone. But I need to use banking and auth apps daily on it, so I assume that isn't an option.
You have to use `termux-setup-storage` to gain access to shared storage. If you're referring to an app's private app data folder, there's no way to access that without root via any app.
that would require you to set up a domain name and use DDNS and trust your registrar, or to just always have your computers at a static IP with no NAT blocking you whatsoever.
