Mozilla Audit of 6 Period Apps Backs Euki, Flags Privacy Flaws at 5 Rivals

Summary
Mozilla Foundation’s review of six leading period-tracking apps singled out Euki as the strongest privacy option and found serious flaws in Stardust, SpotOn, Period Calendar, Flo and Clue.
Euki stood out because it works without an account, stores data locally on the phone rather than on company servers, and is listed in Apple’s App Store as collecting no app data.
The app also includes a real PIN, a fake PIN that hides records behind a technical-difficulties screen, and settings to delete past entries manually or on a schedule.
Mozilla’s warning lands as reproductive-health data faces heightened legal risk, with authorities already using messages and search histories in abortion-related prosecutions.
