'Do Algorithms Care?' is a collaborative installation by Amanda Bennetts and Johanna Einsiedler, critiquing the commercialization of bio-data in healthcare tech. Through open-source DIY smartwatches and interactive data visualization, the project explores personal data's predictive potential for well-being. Designed as a pristine tech store experience, it provokes users to rethink their relationship with data control and privacy. Users actively engage with their own biometric data via smartwatches and interactive visuals, highlighting how data can empower personal wellness or become a tool for exploitation. All resources—code, designs, and processes—are publicly shared, sparking vital conversations around biometric data’s ethical and political implications.
