The map is wildly simplistic, as usual for these Internet takes lol.
In Portugal, for example (where I come from), I don’t know anyone that keeps their shoes in-doors 95% the time. If you’re doing some quick work or holding an event, people might be a bit more lack about taking off your shoes, but I (and many my friends) always make an effort to take some kind of home footware when visiting other people’s homes. As a general rule? Everyone puts some socks/sleepers/flipflops on.

This. And to add to what other commenters have said, by using Bitwarden and paying for their Premium plan (very cheap, just $10/year), even if you don’t use all their features, you’re supporting a good project. It’s critical infrastructure, I think the price is more than fair.
Either way, you should always make periodic backups from any cloud service you use, encrypted of course.
