Short summary: Optima stores all your health data locally on your device. We do not collect, transmit, or sell your personal health information to any third parties. Your data stays yours.
👤 1. Who We Are

💾 3. How We Store Your Data
All data is stored exclusively on your device. Optima does not operate its own servers and does not upload your personal or health data to the internet or any cloud service.
Health data is accessed read-only from Apple HealthKit and is not stored independently by Optima beyond what HealthKit already manages. User-created content (workouts, nutrition logs, etc.) is saved to your device's local storage only.
🚫 4. Data We Do NOT Collect
- We do not collect any data on our own servers
- We do not track your usage with analytics services
- We do not display advertisements
- We do not share your data with any third parties
- We do not sell your data - ever
📍 5. Location Data
Optima requests access to your location only during active run tracking. GPS data is used solely to plot your running route on the map and calculate distance and pace. This data is stored locally on your device as part of your run history. Location data is never transmitted externally.
You may revoke location permission at any time in your iPhone Settings. Revoking this permission will disable the GPS run tracking feature.
📷 6. Camera
Camera access is used only for scanning food product barcodes in the Nutrition module. No photos or video are captured, stored, or transmitted. Camera access can be revoked in iPhone Settings at any time.
🍎 7. Apple Health Integration
Optima integrates with Apple HealthKit to read health data such as steps, heart rate, sleep, and calories. We only request the permissions necessary to display information inside the app. We do not write data to HealthKit except where explicitly initiated by the user (such as logging workouts).
You can manage or revoke Optima's HealthKit permissions at any time via: iPhone Settings -> Privacy & Security -> Health -> Optima.
🧒 8. Children's Privacy
Optima is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will promptly address the situation.
📋 9. Your Rights (GDPR)
If you are located in the European Economic Area (EEA), you have the following rights regarding your personal data:
- Right of access - You can request what data Optima processes
- Right to deletion - You can delete all your data from within the app (Settings -> Delete All Data)
- Right to portability - Your data is stored locally and is accessible to you
- Right to object - You can revoke any permissions (Health, Location, Camera) at any time
Since all data is stored locally on your device, you have full control. Uninstalling the app will remove all locally stored data.
🔄 10. Changes to This Policy
We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated "last updated" date. We encourage you to review this policy periodically.
