PRIVACY FIRST
Your health data never leaves your device. No accounts to create, no data uploaded, no tracking. When you delete the app, your data
is gone — because we never had it.

breastfeeding-aware insights — all explained in plain language.

WORKS WITH APPLE WATCH
Reads wrist temperature and heart rate data from Apple Health to enhance predictions without manual tracking.

Cyla is not a medical device and should not be used as contraception. Predictions are estimates. Always consult a healthcare provider for medical decisions.
