There, beneath the spotlights of d/acc Berlin and before a crowd of Ethereum’s sharpest minds, Migle Rakitaite—visionary behind Wxmen Web3Privacy Now —stood face to face with Ethereum’s own Vitalik Buterin. The air crackled as Rakitaite, joined by fellow privacy advocates, challenged Buterin directly: Why had the Ethereum Foundation neglected to champion and fund crypto-native solutions for safeguarding sensitive health data, particularly for period tracking apps on the blockchain? In that charged moment, as questions of privacy and responsibility echoed through the auditorium, the seeds of PrivyCycle were sown.It is not a theoretical issue. In the United States, the criminalization of abortion in several states has made period-tracking apps dangerous. Data from services like Flo and Clue can be — and has been — subpoenaed in court cases. And while mainstream apps promise privacy, most monetize user data through opaque adtech and analytics deals. The gap between privacy rhetoric and practice is glaring.
