Privacy Policy
Chi Wellbeing, ("Chi", "we", or "our") operates the Chi iOS application (the "app"). We are committed to protecting your personal data and providing full transparency about how we use information to support your wellness journey.
By using the app, you agree to the collection and use of information as described in this Privacy Policy.
1. Health Data
With your explicit consent, Chi uses Apple’s HealthKit framework to read and/or write data stored in the Apple Health app on your device. The app does not access this data without your permission, and all processing is performed locally on your device. We do not store, transmit, or share this data with third parties.
Chi may access the following Apple Health data types:
Heart Rate
Heart Rate Variability (HRV)
Resting Heart Rate
Respiratory Rate
VO2 Max (Cardio Fitness)
Wrist Temperature
Blood Oxygen
Sleep Duration & Sleep Schedule
Step Count
Stand Hours
Exercise Minutes
Active & Total Calories
Time in Daylight
Vitals Alerts (Heart Rate, Blood Oxygen, Respiratory Rate, Wrist Temperature)
These metrics are used solely to calculate your Body Energy score and generate non-medical lifestyle guidance. We do not use HealthKit data for advertising, marketing, or profiling.
2. Location Data
If you grant permission, Chi may use your location to provide context to wellness insights (e.g., daylight exposure or outdoor activity). Location data is processed on your device and never stored or transmitted.
3. Contact Information
If you provide your email address (e.g., for support, account identification, or updates), we may store your name and email securely. We do not use this information for advertising or sell it to third parties. You can request deletion anytime by emailing chiapponline@gmail.com
4. Usage Analytics (Non-Health Data)
To understand app performance and improve functionality, Chi uses third-party services that collect non-health-related usage data:
Sentry – crash reporting
Firebase – usage statistics
Mixpanel – interaction analytics
These services do not access HealthKit or location data.
5. Identifiers
Chi may use Apple’s Identifier for Advertisers (IDFA) to understand general usage trends. This identifier is randomly assigned by iOS and does not contain personal information. We do not use IDFA for displaying ads, and Chi is fully ad-free.
You can disable tracking anytime via Settings > Privacy & Security > Tracking.
6. Security
We use industry-standard security measures to protect your information. However, no method of data transmission or storage is 100% secure. We strive to ensure that your data remains private and safe at all times.
7. Use of Colors and Insights
Chi uses color-coded notifications and visual indicators to enhance the user interface. These colors are designed for clarity and visual feedback only. They do not indicate medical status, risk, or urgency.
All wellness insights are generated by proprietary algorithms based on Apple Health data and publicly available health guidelines (e.g. WHO, AHA, ACSM). These insights are non-medical and should not be used to diagnose or treat health conditions.
8. Changes to This Policy
We may update this Privacy Policy from time to time. Any changes will be posted within the app. For major updates that affect your data rights, we will request your consent again.
We will never modify this policy to allow for new types of data collection or sharing without your permission.
9. Contact Us
If you have any questions or concerns about this Privacy Policy or your data, please contact us at:
Chi is a wellness app, not a medical tool. For health concerns, always consult a licensed medical professional.
