Transparency and security
A plain-language summary of how Luna handles your data and keeps it secure. For the full legal text, see our privacy policy and terms.
Last updated: June 8, 2026
Where your data lives
Luna’s product data is hosted in the European Union, in Frankfurt, Germany. It is encrypted in transit and at rest.
We do not move your cycle data to the United States.
What we never do
Luna is a subscription product, not an ad-supported one. That choice removes the incentive to exploit your data.
- We do not show ads.
- We do not sell, rent, or trade your personal data.
- We do not use your cycle data for behavioral advertising.
What a partner can never see
Partner mode shares useful context without exposing private information. These fields are filtered at the data level, not just hidden in the interface, so a partner never sees:
- Your private notes
- Your basal body temperature
- Your intimacy logs
- Your raw symptom entries
Deleting and exporting your data
You can delete your account in one tap from inside the app. Deletion is immediate and removes your associated personal data, in line with your right to erasure under GDPR (Article 17).
You can also request a copy of your data, and ask us to correct it.
Who processes data for us
We rely on a small set of trusted providers to run Luna. Each one only receives what it needs to do its job.
- Supabase: EU-hosted database and authentication (Frankfurt)
- Brevo: email (newsletter and product notifications)
- Apple: App Store distribution and in-app purchases
- RevenueCat: subscription management
- Google Analytics and Mixpanel: aggregate, privacy-conscious usage analytics
Who can use Luna
Luna is not intended for anyone under 16, and accounts for under-16 users are blocked.
