What Data PACE Reads

PACE reads the following health data from Apple HealthKit to compute your scores:

• VO₂max (cardiorespiratory fitness)
• Heart Rate Variability (HRV / RMSSD)
• Resting Heart Rate
• Heart Rate Recovery (post-exercise)
• Sleep Analysis (duration, stages, timing)
• Wrist Temperature (sleeping baseline deviation)
• Blood Oxygen Saturation (SpO₂)
• Workout Sessions (type, duration, heart rate)

How Your Data Is Processed

All scoring computations run entirely on your iPhone using Apple's on-device frameworks. PACE does not have servers and does not transmit health data over the internet. Scores are computed from the HealthKit data listed above and stored locally.

What PACE Does Not Do

• Does not create user accounts or collect email addresses
• Does not use analytics, crash reporting, or tracking SDKs
• Does not share data with third parties
• Does not store data in the cloud
• Does not require an internet connection to compute scores

Challenge Feature

The "Challenge a Friend" feature generates a shareable URL containing only a single integer — your Vitality Age number. No names, identifiers, or health details are included in the URL.

Example: https://p-formance.run/challenge?age=26

Data Storage & Deletion

Score history is stored locally on your device using SwiftData (Apple's on-device database). iOS encrypts this data at rest.

To delete all PACE data, simply delete the app from your iPhone. This permanently removes all stored scores and preferences.

Children's Privacy

PACE is not intended for use by children under 13. We do not knowingly collect data from children.

Changes to This Policy

We may update this policy from time to time. The "last updated" date at the top will be revised accordingly.
