I routinely use my (U.S.) credit card abroad and never had issues. I don't have any banking app on my phone, which runs Graphene, because I do not need access to banking on the go. Things such as airport lounges, co-working spaces, exercise classes, may be valuable, but none of these things is more important than my freedom. I do not tolerate the thought that some company may track which services I use and where I go without my consent. I therefore do not use proprietary apps on my phone. If something does not work in the browser (Vanadium), I will do without it.
