## What is CycleNest?

CycleNest is a fully offline period and wellbeing journal that keeps sensitive records in your hands.

• Record period start and end dates
• Log daily flow, symptoms, mood, and an optional note
• Review periods, daily entries, and estimate ranges in a calendar
• See median cycle and period lengths, variability, and common symptoms
• Get conservative, explainable ranges based only on your valid history
• Enable an optional local reminder; permission is requested only when you choose it
• Export a JSON backup or CSV, and inspect a backup before replacing local data
• Native support for iPhone, iPad, Dark Mode, and Dynamic Type

No account or cloud sync, and no ads, analytics, tracking, or third-party SDKs. The app does not access the network at runtime; entries stay in its on-device sandbox.

Cycle patterns and date ranges are for personal reference only. They are not medical advice and must not be used for diagnosis, fertility planning, contraception, pregnancy decisions, or medical care.
