  • Period tracking apps vary in privacy practices, with some sharing user health data with third parties like Google, Meta, and TikTok.
  • Stardust was found sharing detailed reproductive health data with RudderStack, though it claims data is anonymized and not misused.
  • Euki is recommended for storing all health data on-device, allowing anonymity and offering a decoy feature for privacy.
  • Flo and Clue scored well for transparency and controls but store health data on servers, raising breach or legal request risks.
  • Past privacy scandals include Flo's FTC settlement and online sales of device lists from apps like Clue and Period Calendar.
  • Experts warn that data from period trackers could be used in criminal cases post-abortion law changes, highlighting regulatory gaps in the U.S.
