Assuming your bank already has all of your information, what’s the problem with them knowing your IP?

And how often do you need to use your banking app? Could you connect from a local free WiFi network from a library or something?

What about just logging in with your web browser? I’ve been using GOS for going on 4 years now and haven’t had any issues with it. Is there anything specific the app provides that you need that isn’t available through browser?

There’s also SeaweedFS that I’ve used as an S3 compatible fileserver
