I interviewed Clue Period Tracking App: Does Ethical FemTech Actually Exist?

My search for ethical FemTech led me to Berlin This investigative deep dive asks a simple but urgent question: what does it take to build ethical FemTech? After spending most of 2025 analysing menstrual cycle tracking apps, data privacy practices, and transparency in women’s health technology, I traveled to Berlin for exclusive access to Clue — founded by Ida Tin, the woman who coined the term FemTech, and to speak with their CEO, Head of Science, and Director of Data. 💡What’s In This Video: • Why Berlin holds the key for ethical FemTech innovation • The history of surveillance in Berlin and how the city has transformed into a hub for digital rights activism • How EU regulations like GDPR protect sensitive health data • Inside access to Clue’s Berlin head office • Interviews with Clue CEO Rhiannon White, Head of Science Cornelia Hainer, and Director of Data Linda Cen • What sets Clue apart in an unregulated industry As a Fertility Scientist and women’s health advocate, I’ve spent 2025 investigating how women’s health apps use our most intimate information and what true accountability looks like. This video is not sponsored in any way. This investigation was undertaken independently and comes purely from my own curiosity, concern, and commitment to uncovering the truth about FemTech.
