Today’s service providers must notify users of their privacy policies and obtain user consent in advance. Frameworks that impose these requirements have become mandatory. Originally designed to protect user privacy, obtaining user consent in advance has become a mere formality. These problems are introduced by the gap between service providers’ privacy policies, which prioritize the observance of laws and guidelines, and user expectations of these policies. In particular, users wish to easily understand how their data will be handled. To reduce this gap, we provide a tool that supports users in reading privacy policies in Japanese. We assess the effectiveness of the tool in experiments and follow-up questionnaires.
