Are my users' credentials taken abroad at any time during SSO?

Our country’s regulation (which has additional conditions for the finance industry) says that you can’t use cloud services to store a user’s sensitive information. @Jagster So we can use cloud services as long as we don’t store sensitive data there.

It is OK if only email address is stored abroad - this alone is not considered sensitive info. Still, if at any point I store email address together with the full name of the user, this is considered sensitive information, since the user is now identifiable as a person. I’m worried because after SSO is used for login, since I can see our users’ email address and full name on the platform, I don’t know whether this data sent to and stored in the Discourse hosting, it is against our local regulations.

To demonstrate the mindset with our regulations: Say, for example, a 3rd party with malicious intent gets access to the physical drives of Discourse’s cloud server in the EU. Would they be able to read our users’ full name & email together, given that they logged in with SSO?
