Privacy Policy

Last updated: March 2026

RunOrithm is built on one principle: your health data is yours. It never leaves your device, is never sent to any server, and is never seen by us.

1. Overview

RunOrithm is an adaptive running coach for iOS that generates and manages personalized training plans entirely on your device. The app does not require user accounts and does not collect personal data on any server. This policy explains the limited information handled so the app can function and be distributed on the Apple App Store.

2. Data We Handle

All training plans, workout schedules, run history, and settings are stored locally on your device. RunOrithm reads the following data from Apple Health, solely on-device, to adapt your training plan:

Heart Rate Variability (HRV)
Resting Heart Rate
Sleep data
VO2 Max
Completed workouts

This data is read locally and processed on-device to compute readiness scores and adjust your plan. It is never transmitted to RunOrithm or any third party.

If you use multiple Apple devices, your training data syncs via iCloud through Apple's CloudKit service. This encrypted copy lives in your personal iCloud account. RunOrithm cannot access it.

3. How Information Is Used

Health data accessed from Apple Health is used exclusively to:

Generate and adapt your running training plan
Compute your readiness and fitness scores
Schedule structured workouts to your Apple Watch

We do not run analytics, advertising, or tracking frameworks. No data is sold, shared, or used for marketing purposes.

4. Apple Watch

When you send a workout to your Apple Watch, RunOrithm uses WorkoutKit to transfer structured workout data directly to the native Apple Watch Workout app. This transfer happens locally over your paired devices and does not involve any external servers.

5. Sharing and Retention

No information is shared with third parties. Your data is removed when you delete the app. iCloud copies are controlled entirely by Apple and follow your iCloud storage settings.

6. Your Choices

Edit or delete your training plan and workout history within the app
Revoke Apple Health permissions at any time via iOS Settings → Health → Apps
Control iCloud sync through iOS Settings → Apple ID → iCloud

7. Children's Privacy

RunOrithm is not directed at children under 13. We do not knowingly collect any information from children.

8. Changes to This Policy

If this policy changes materially, the updated version will be posted here with a revised date.
