Ciclunia: Cycle & Body Diary

Ciclunia is a calm companion for your menstrual cycle and your body. It shows where you are in your cycle, estimates your next period and fertile window based on your own history, and lets you log your day in a few taps.

WHAT YOU CAN DO
• See your cycle day, phase and an estimate for the next period and ovulation
• Log period, pain, mood, energy, cervical mucus, basal temperature, sleep, weight, skin, symptoms, medication and notes
• Follow a month calendar with recorded and estimated days
• Read statistics and charts: cycle length, period duration, temperature curve, symptom patterns
• Document your body with photos, compare before and after, browse your personal timeline
• Earn gentle levels and achievements, without streaks or guilt
• Get optional reminders that never show cycle details on the lock screen
• Export everything as JSON or CSV, or delete all data with one tap

HONEST ESTIMATES
Every prediction is labelled as an estimate with an uncertainty window and explains what it is based on. Ciclunia never states a diagnosis and never claims a day is "safe". Calendar estimates alone are not a reliable contraceptive method.

PRIVACY
Your entries are stored on your device only. No analytics, no tracking, no accounts. Photos are downscaled, stripped of location data and stored encrypted. One exception you control: photos you add are also sent to the developer to improve the app (category and cycle day only, under a random pseudonym, never your name, dates or notes). This is shown during setup and can be switched off at any time; switching off deletes the shared copies.

Ciclunia is a tracking and information tool, not a substitute for medical advice.

Available in English, German, Spanish, French, Italian, Polish and Ukrainian.
