JURISDICTIONUS
NOTENote content is end-to-end encrypted, but Standard Notes Ltd is the U.S. service operator and contracting entity under U.S. law. Account, billing, support, IP/device, and third-party payment metadata remain outside note-content encryption; Proton ownership does not make the service operator Swiss.
