Data Practices Overview
We believe in absolute transparency about where your personal information lives and how it is protected. Below is an itemized breakdown of our data handling practices.
1. Stored Exclusively on Your Physical Device
All personal cycle and lifestyle logs are encrypted on-device via SQLCipher. They are never sent to Mentarich LLC or any remote cloud analytics servers:
- Period start and end dates, flow intensity, and duration history
- Symptoms, mood check-ins, and daily reflections
- Fertility-awareness records (Basal Body Temperature, LH tests, cervical mucus)
- Movement activity logs, workout notes, and duration records
- Care points and Moon Garden progression milestones
- Doctor-ready Health Report PDF documents
2. Processed by App Store & Billing Infrastructure
If you purchase a YUVIX Premium subscription, Apple, Google, and RevenueCat process the minimum required commerce identifiers to activate your purchase:
- Anonymous customer app user identifier (random UUID)
- Product ID purchased (Monthly or Annual plan)
- Entitlement active status and subscription expiration timestamp
- Platform receipt validation token
Zero Health Cross-Contamination: No cycle dates, period logs, symptom entries, or medical report contents are ever included in billing payloads.
3. What We Never Do
- We never sell or rent your personal information to third parties.
- We never use reproductive or menstrual health data for targeted advertising or user profiling.
- We never upload your generated Doctor-Ready PDFs without your explicit operating-system share command.
4. User Control
You have complete control over your records at all times. You can view, edit, or permanently erase your local database via Settings > Data & Privacy > Delete All Local Data.
