Personal cycle awareness
Your cycle, understood.
Kept on your device.
Cyli is an account-free place to record your period and daily wellbeing. Your setup answers and health logs are stored encrypted on your device, and no Cyli server receives them.
No accountNo health-data backendWellness-only by design
Encrypted on your device
Setup answers and health logs live in an encrypted local database, not on a Cyli server.
Honest about limits
No medical advice, diagnosis, contraception or fertility guarantees. When history is thin, Cyli says so.

What you can do
Made for the moments between dates
Optional setup, flexible daily logging, a calm calendar, insights and reports, an Apple Watch companion and ten interface languages.
Log what matters
Period status and flow, symptoms, mood, energy, sleep, pain and medication - record only what you choose, in any of ten languages.
A calmer calendar
See the days you recorded, keep facts visually distinct from expected ranges, and edit or delete any day.
Insights, reports and Premium patterns
Review recorded history with honest empty and insufficient-data states. Optional Cyli Premium adds the layer that reads your history: symptom patterns, your personal baseline and how your variability is trending.
On your wrist
The Apple Watch companion logs from your wrist; records move only between your paired iPhone and Watch, never through a Cyli server.
Privacy
Personal should feel personal.
Cyli has no analytics, no advertising, no third-party crash reporting and no HealthKit integration. Health logs are never sent to Cyli. You can delete all local data from Settings at any time.
