# Privacy Policy for CareHer (Lunaflow Ai)
**Last Updated:** October 20, 2025
## Introduction
CareHer (also known as "LunaFlow Ai") is committed to protecting your privacy. This Privacy Policy explains our practices regarding the collection, use, and disclosure of information when you use our mobile application.
Our primary commitment is to privacy—all your health data stays on your device and is never transmitted to our servers or shared with third parties. We believe period tracking should be completely private.
## Information Collection and Use
### Data Stored Locally on Your Device
All personal data is stored **solely on your device** and includes:
* Menstrual cycle dates and flow information
* Symptoms and mood tracking data
* Medication and pill tracking
* Personal notes and logs
* App preferences and settings
* Tampon reminders and period predictions
This data is used to provide you with period tracking features, cycle predictions, and personalized insights. You can delete all data at any time through the app's settings or by uninstalling the app.
### Analytics and Performance Data
We use Firebase Analytics in a limited capacity to collect **anonymous** usage statistics that help us improve the app. This data:
* Does NOT include any of your health information
* Does NOT include any personally identifiable information
* Contains only generic app usage patterns (such as which features are commonly used)
* Does NOT track your specific actions or behavior
You can opt out of analytics collection through your device settings.
### AI Assistant Features (Luna)
Our app includes an optional AI assistant (Luna) powered by Google Gemini. When you use this feature:
* Only anonymized cycle phase information and general symptoms are shared with the AI service
* No personal identification information, exact dates, or location data is ever transmitted
* Conversations are processed in real-time and not permanently stored on Google servers
* All AI feature analytics are stored locally on your device and can be cleared at any time
* You can disable AI features completely through settings
## Data Sharing and Disclosure
We do NOT share your data with any third parties. Period.
* Your health data never leaves your device
* We do not have access to your personal data
* We do not sell your data to advertisers or data brokers
* We do not share anonymized data for research purposes
## App Permissions
Our app requires the following permissions:
* **Notifications**: To send period predictions, medication reminders, and tampon change reminders
* **Schedule Exact Alarm/Use Exact Alarm**: To schedule precisely timed reminders
* **Receive Boot Completed**: To restore your notification settings after device restart
* **Use Biometric**: Optional for added security to protect your sensitive health data
All permissions can be managed or revoked through your device settings.
## Data Security
We implement appropriate security measures to protect your personal information:
* All your data is stored locally on your device
* You can enable biometric authentication for added security
* No data is transmitted over networks except for anonymous app analytics
* We use industry-standard security practices for any app operations
## Data Retention and Deletion
Since all your data is stored locally on your device:
* Your data remains on your device until you choose to delete it
* You can delete specific logs through the app interface
* You can delete all data using the "Clear All Logs" option in settings
* Uninstalling the app will permanently delete all your data
## Children's Privacy
Our app is intended for users who manage menstrual cycles, which may include individuals under the age of 13. We do not knowingly collect personal information from children. Because our app does not transmit personal data from the device, children's information remains private on their device.
## Changes to This Privacy Policy
We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last Updated" date.
## Your Rights
You have complete control over your data:
* Access: All your data is accessible directly through the app interface
* Correction: You can edit any data entries within the app
* Deletion: You can delete individual entries or all data through the app settings
* Export: You can export your data through the app's backup features
