Privacy Policy
This Privacy Policy explains how Luna ("we," "our," or "us") collects, uses, and protects your information when you use our mobile application.
By using Luna, you agree to the practices described in this policy.
1. Data We Collect
To provide personalized cycle, fertility, and pregnancy insights, Luna collects only the data you choose to share with us:
- Email address (for sign-in)
- Cycle data: period dates, cycle length, symptoms, mood entries
- Profile context: birth date, mode (cycle / pregnancy / postpartum), goals
- Pregnancy data (if applicable): due date, milestones
- Postpartum data (if applicable): baby's birth date, breastfeeding status
- Journal entries you write in the app
- Conversations with the Luna AI companion
- Notification preferences
We do not collect contacts, location, photos, or any data unrelated to your wellbeing journey.
2. How We Use Your Data
Your data is used to:
- Calculate cycle phase, fertile window, and predictions

- Send notifications you've opted into
Your data is never sold, never used for advertising, and never shared with marketers.
3. Where Your Data Is Stored
Your data is stored securely on Supabase (PostgreSQL hosted on AWS, encrypted in transit and at rest).
