1. Introduction
CymCym ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we handle your data when you use the CymCym iOS application ("App").
2. Data Collection
We do not collect, store, or transmit any personal data. CymCym is designed with privacy as a core principle:
- All mood data, habits, and insights are stored locally on your device only
- No data is sent to external servers or third parties
- No analytics or tracking is performed without your explicit consent
- No user accounts or authentication is required
3. Health Data (HealthKit)
If you choose to connect CymCym with Apple HealthKit:
- HealthKit data (steps, sleep, heart rate) is read only with your explicit permission
- Health data is processed on-device only to generate insights
- Health data is never transmitted off your device
- You can revoke HealthKit access at any time in iOS Settings
4. Mental Health Data
As a mental health and wellness app, we understand the sensitive nature of mood data. All mood logs, notes, and emotional insights are:
- Encrypted at rest using iOS standard encryption
- Accessible only on your device
- Never shared with third parties, advertisers, or researchers
- Completely under your control
5. Data Storage
All data is stored using Apple's SwiftData framework, which stores data locally on your iOS device. Data is:

- Included in your device backups (iCloud or iTunes) if you have backup enabled
- Deleted when you uninstall the app
6. Third-Party Services
CymCym does not integrate with any third-party analytics, advertising, or data collection services. The app operates entirely offline and on-device.
7. Children's Privacy
CymCym is not intended for children under the age of 13. We do not knowingly collect data from children. If you are a parent or guardian and believe your child has provided us with personal information, please contact us.
8. Your Rights (GDPR)
Even though we don't collect data, you have the right to:
- Access: View all your data directly in the app
- Delete: Delete any mood entry or all data by uninstalling the app
- Export: Export your data (feature available in-app)
