Actually I am planning to shut down emergency scenario of banking apps (installed only because of early pandemic situation) and using only the web access point trough real computer. There is no absolute in this, but I am certain that in my day to day life I have enough privacy compared to regular users of a smartphone or computer. This old iPhone is only active for the banking transaction and only in use cases when I don't have a laptop around. So the compromise is acceptable.
