Calmax Systems ("we", "us") respects the privacy of users of the Cylla app ("the App"). This policy explains how we handle your data.

1. Data Collection

The App stores the following data on your device:

• Cycle tracking data (period dates, flow intensity, cycle length)
• Symptom and mood logs
• Health notes and observations
• AI conversation history
• App settings and preferences

We do not collect, transmit, or store any of your data on external servers. All data remains on your device and in your iCloud account (if iCloud sync is enabled).

2. Sensitive Health Data

We understand that reproductive health data is deeply personal. That is why we designed Cylla to operate entirely on your device. Your health data is never sent to any server, never shared with third parties, and never used for advertising or analytics.

3. On-Device AI

The App uses an AI language model that runs entirely on your device. Your health data and AI conversations are processed locally and are never transmitted externally. We have no access to your AI interactions.

4. HealthKit Integration

If you enable HealthKit integration, the App may read and write cycle tracking data through Apple HealthKit. HealthKit data is governed by Apple's privacy policies and is never sent to our servers.

5. Third-Party Services

The App does not include any third-party analytics, advertising, or tracking tools. We do not share your data with anyone.

6. In-App Purchases

Premium features are available through Apple's App Store. All payment processing is handled by Apple. We do not access your payment information.

7. Children's Privacy

The App is not intended for children under 13. We do not knowingly collect personal information from children under 13.

8. Changes to This Policy

We may update this policy from time to time. Changes will be posted on this page.
