Privacy Policy

1. Who We Are

Falcata Run is developed by Radim Simanek, an independent developer located in Switzerland. For the purposes of the General Data Protection Regulation (GDPR), Radim Simanek, Unterfeldstrasse 2, 4332 Stein, Switzerland, is the Data Controller. If you have questions about this policy, contact us at info@falcatarun.com.

2. Data We Collect

Health & Fitness Data

When you grant HealthKit permissions, the app reads and writes:

• Workout sessions (sprint type, duration, distance)
• Heart rate, resting heart rate, and heart rate variability
• Running dynamics (ground contact time, stride length, vertical oscillation, running power)
• Active energy burned
• Workout effort score (your self-reported RPE)

This data is stored in Apple HealthKit on your device and synced via iCloud Health under your Apple account. We do not have access to your iCloud Health data.

Motion Sensor Data

During sprints, the Apple Watch records accelerometer and gyroscope data at 100 Hz. This data is used to analyze:

• Sprint acceleration and deceleration curves
• Arm swing mechanics and range of motion
• Ground contact time and step cadence
• Stride symmetry and gait analysis

Curve data is stored locally on your device and in your personal iCloud Drive container. If you opt in to data sharing, anonymous curve data and sprint metrics may be securely uploaded to Firebase Firestore to help us improve our sprint detection algorithms. This data is not linked to your identity.

Location Data

When you grant location permissions ("While Using"), the app collects GPS coordinates during sprints to:

• Verify sprint distance
• Detect track curves and lane position (for 200m and 400m sprints)
• Record workout routes in HealthKit

Location data is only collected during active sprint sessions, not in the background.

Usage Analytics

We collect anonymous usage events via Google Firebase Analytics (also referred to as Google Analytics) to understand how the app is used and to improve it. The app generates a random device identifier (UUID) to associate events with a device session — this identifier is not linked to your name, Apple ID, or any personal information. Examples of events we collect include:

• Workout lifecycle events (started, completed, cancelled)
• Sprint events (distance selected, sprint recorded, sprint metrics)
• Screen views and feature usage
• Settings changes (theme, notifications)

These events do not contain personally identifiable information. Usage analytics are only collected if you opt in. You can enable or disable data sharing at any time in the app's settings. Sprint workout data included in analytics (such as distance, duration, and performance metrics) is used exclusively to improve the app's algorithms and features — never for advertising or marketing.

Crash Reports

If the app crashes, we receive an anonymized crash report including the stack trace, device model, and OS version. This helps us fix bugs. Crash reports are collected under GDPR Article 6(1)(f) (legitimate interest in app stability) and do not require opt-in consent.

3. Data We Do Not Collect

• Name, email address, or other personal contact information
• Age, gender, or demographic data
• Photos, microphone audio, or camera data
• Advertising identifiers (IDFA)
• Cross-app tracking data
• Background location data

The app does not require you to create an account.

4. Third-Party Services

Data sent to Google Firebase is processed in accordance with Google's Firebase Privacy Policy. Google acts as a data processor on our behalf and does not use this data for advertising purposes. When data is transferred to Google servers outside of the European Economic Area (EEA), it is protected by Standard Contractual Clauses (SCCs) as required by the GDPR.

5. Sprint Data Collection for App Improvement

If you opt in to data sharing, the app may upload anonymous sprint session data (including motion sensor curves, sprint metrics, and GPS-derived distance measurements) to Firebase Firestore. This data is used exclusively to:

• Analyze sprint detection accuracy and improve algorithms
• Debug reported issues
• Validate performance analysis features

This data collection requires your explicit consent, which you can grant or revoke at any time in Settings > Privacy. Uploaded data does not include your name, Apple ID, or any personal identifiers.

6. How We Use Your Data

All data we collect is used solely to:

• Provide sprint tracking and performance analysis features
• Sync your data across your Apple Watch and iPhone
• Improve app stability and fix bugs
• Improve sprint detection algorithms and performance analysis using anonymous workout data
• Understand feature usage to guide development
• Validate sprint results for leaderboard integrity (via Apple Game Center)

We do not sell, rent, or share your data with third parties. We do not use your data for advertising, ad targeting, or marketing purposes. All data collection exists solely to improve Falcata Run.

7. Data Storage and Security

• On-device: Health data is stored in Apple HealthKit's encrypted store. Curve data is stored in your iCloud Drive container. App settings are stored in the app sandbox.
• In transit: All data transferred between your Watch and iPhone uses Apple's encrypted WatchConnectivity framework. All data sent to Firebase uses HTTPS/TLS encryption.
• Cloud: Firebase data is stored in Google Cloud infrastructure with encryption at rest.

8. Data Retention

• HealthKit data is retained according to your Apple Health settings and is under your control.
• iCloud Drive curve data is retained as long as you use the app. You can delete individual sprints from within the app.
• Firebase Analytics data is retained for 14 months, then automatically deleted by Google.
• Crashlytics data is retained for 90 days.
• Firestore sprint data (opt-in only) is retained for 12 months, then securely deleted.

9. Your Rights

You can:

• Delete your sprint data from within the app at any time
• Revoke HealthKit permissions in Settings > Health > Data Access & Devices
• Revoke location permissions in Settings > Privacy & Security > Location Services
• Export your data using the app's backup feature
• Opt out of usage analytics at any time in Settings > Privacy
• Request deletion of any data stored in Firebase by contacting us at info@falcatarun.com
• Lodge a complaint with your local data protection supervisory authority if you reside in the EEA or UK

10. Children's Privacy

Falcata Run is not directed at children under 13. We do not knowingly collect data from children under 13. If you believe a child has provided us with data, please contact us and we will delete it.

11. Changes to This Policy

We may update this privacy policy from time to time. Changes will be posted on this page with an updated effective date. Continued use of the app after changes constitutes acceptance of the updated policy.
