Kaluna: Private Period Tracker

Kaluna is a calm, private period tracker. Everything you log stays on your phone. There is no account, no cloud, no ads and no tracking, and the app does not even ask for internet access.

WHY KALUNA • Private by design: your data lives only on your device, in an encrypted database. Nothing is uploaded, ever. • Pay once, keep it: one purchase, no subscription, no ads, no in-app purchases. • Calm and clear: a quiet design that tells you what you need to know and nothing more.

TRACK WHAT MATTERS • Log flow, mood, cramps, temperature, symptoms and notes in a few taps. • See your cycle on a calendar with your logged days and estimated windows. • Predictions are shown as ranges, never one "exact" day, because every body is different. • Follow trends in your cycle and period length over time, based only on your own logs.

FOR EVERY STAGE • Perimenopause mode: track hot flashes and gaps between periods, without predictions. • Postpartum mode: log your recovery after birth, with gentle guidance on when to contact a professional. • Late-period check-in: a short guided check when your period is late.

KEEP IT PRIVATE • App lock with a PIN, plus fingerprint or face unlock where your phone supports it. • Hide the app from the recent apps screen and block screenshots. • A home screen widget in Light, Dark or Glass style. It shows nothing sensitive while the app is locked.

TAKE IT WITH YOU • Export a summary PDF to share with your doctor, or print it. • Back up and restore your data on your own terms.

IMPORTANT Kaluna is not a medical device. It does not diagnose, treat or prevent any condition. Predictions and insights are estimates based on what you log. If you are worried about your health, talk to a healthcare professional. If you think you need urgent care, contact your local emergency services.
