A clear account of how this website is protected.
Updated October 17, 2026
Scope of this website
twobrain.jp presents our research and development work. It has no sign-in, payments, file uploads, or AI input features.
Transport and browser protections
The site uses HTTPS. Browser policies restrict embedding by other sites, resource loading, outgoing connections, and access to capabilities such as the camera and microphone.
Checks before updates
Before publication, we check appearance and behavior and review known vulnerabilities in dependencies. These measures are maintained over time; they do not guarantee the absence of every risk.
Products in development
.I, Codef, and .I Store are in development. Protections on this website are not a certification or assurance about future products. Their data practices and terms will be described before those services become available.
