Cycle Tracking

Log period start and end, flow intensity, and symptoms. Lunavi builds your personal baseline over time.

Mood Logging

Track emotional patterns alongside your cycle. See which moods correlate with which phase over months of data.

Cycle Insights

Beautiful charts show your patterns across months. Cycle length trends, symptom frequency, mood shifts — all local, all private.

Zero Advertisements

Lunavi contains no advertising SDKs. Not a single ad, ever. Your health data is not a product.

Privacy by Architecture

All data is stored in a local Android Room database. The developer has no server to receive your data — because there isn't one.

Room Database

Private Reminders

Period and fertile window reminders are local notifications. Nothing leaves your device to deliver them.

Data Export

Export your complete cycle history to a file whenever you want. Your data, your file, on your terms.
