Obviously we wish we could go global, but unfortunately we can’t immediately do that as what we do depends heavily on the legal situation. There are two mechanisms that can contribute to a wider utility of our service. The first are adequacy mechanisms, whereby the European Commission encourages on a bilateral basis other countries to raise their data protection standards, in order to enter into free flow of personal data sort-of-trade agreements. You can look at it here. As you can see the list of countries is not bad, and with the GDPR coming in force these other countries will have to improve the situation. It is also expected that Korea and Japan will join, possibly as soon as early 2018.
As Jérôme mentioned, awareness is definitely rising in the United States, and some states are making small progress (California, Illinois), although they always have a closed and predefined list of which categories of data are personal data, which is in my view problematic.
