CyclaZen

CyclaZen is a quiet place to track your cycle. No ads, no account, no data collection. WHAT IT DOES • See the day you're on and the phase you're in, at a glance • Log flow, mood, symptoms and energy in a few taps • View past cycles and predicted days on the calendar • Insights drawn from your own logs: average cycle length, variation, period length • Gentle reminders before your period, when your fertile window opens, or for a daily check-in • Short, plain articles on cycle phases and the questions people actually ask YOUR DATA STAYS WITH YOU Nothing you log leaves your phone. No account, no sign-in, no analytics, no third-party trackers — the app makes no network requests at all. Export everything as CSV or JSON whenever you like, and erase all of it whenever you like. A CALM DESIGN Soft colours, readable type, no nagging. Logging takes seconds, even on a busy day. GETTING STARTED We begin with one question: when did your last period start? The app never invents a history — it works only from what you enter, and adjusts as you log. COMPLETELY FREE No ads, no subscription, no locked features. CyclaZen is not a medical device and does not provide medical advice. Predictions are statistical estimates based on your own logs and should not be used as a method of contraception. If you have a health concern, speak to a healthcare professional.
