Privacy-first cycle tracking for Kawasaki, Japan. Smart predictions, mood insights, dark mode & zero data selling.
Good morning, Emma
From Asia & Pacific to your daily commute in Kawasaki, cycle tracking should be private, fast, and free of ad clutter.
In Kawasaki, many people manage busy urban schedules while keeping health apps on their phones — making a quick home-screen tracker ideal for daily check-ins. MyPeriod encrypts sensitive notes, avoids selling data, and offers smart predictions after you log two or more periods.
Health apps used in Japan should respect APPI (Act on Protection of Personal Information). MyPeriod minimizes data collection, lets you export or delete your account, and keeps predictions tied to your own history — not advertiser profiles.
Setup takes under a minute. Log flow and symptoms, track moods, read phase-aware insights, enable dark mode, add MyPeriod to your home screen for gentle reminders, and explore the in-app Cycle Guide — all free.
With access to National Health Insurance — universal coverage with co-payments, many in Kawasaki still benefit from a personal timeline between visits. Export PDF or JSON summaries to share what matters.
