MetricFit Privacy Policy

Privacy Policy

Last Updated: July 14, 2025

This Privacy Policy explains how MetricFit handles your information, particularly your sensitive health data. This document is for your reference and is accessible at any time within our app by navigating to Settings > About > Privacy Policy.

Our core commitment is to your privacy. The final health readings, whether entered manually or captured via OCR, are only stored in your personal HealthKit database on your Apple device. Our app functions primarily as a viewer and entry tool for your HealthKit data, and we do not store, share, or transmit your health readings to any server.

1. HealthKit Integration

Our app uses HealthKit integration for two primary purposes:

• To Store Your Data: To act as a convenient tool for you to save health data into the central and secure HealthKit database on your device.
• To Display Your Progress: To read data from HealthKit in order to present it to you in the form of intuitive charts and graphs, allowing you to track and analyze your health trends over time.

Health Data We Access (With Your Explicit Consent)

Our app will only access or write data to HealthKit with your explicit permission. We will request your permission to read and/or write the following specific data types:

• Heart Rate (HKQuantityTypeIdentifierHeartRate)
• Weight (HKQuantityTypeIdentifierBodyMass)
• Blood Glucose (HKQuantityTypeIdentifierBloodGlucose)

You will be prompted by iOS to grant permission for each data type individually. You are in complete control and can choose which data you wish to share.

2. Optional Image Processing for Data Entry (OCR)

To simplify data entry, our app offers an optional feature to capture an image of your health instrument’s display. To perform Optical Character Recognition (OCR), this image is securely transmitted to Google Cloud AI services for automated processing.

• Purpose: The image is used solely for extracting the numerical data for entry into the app. The extracted number is then prepared for you to confirm and save to HealthKit.
• Data Retention: The image data is processed by Google and is not stored or retained by us or Google after the OCR process is complete.
• User Choice: This feature is entirely optional. You can always choose to enter data manually, in which case no image is taken and no data ever leaves your device for processing.

By using the OCR feature, you acknowledge that the image data will be processed by Google in accordance with their Privacy Policy. You can learn more about Google’s privacy practices here: https://policies.google.com/privacy.

3. Data Storage, Security, and Sharing

We are committed to protecting your privacy. Our data handling practices are designed to be secure and transparent:

• No Health Data on Third-Party Servers: Your HealthKit data (the final readings) is never transferred to, stored on, or processed by our servers or any third-party servers. All health data read from HealthKit remains on your device.
• No Third-Party Sharing: We do not share your HealthKit data with any third parties, data brokers, or advertising networks.
• No Commercial Use: Your health data will not be used for advertising, marketing, or any purpose other than providing and improving the app’s core health management features.
• PDF Export: With your direct action and consent, the app can generate a PDF report of your health data. This export is performed locally on your device, and you decide if and with whom you share it.

4. Your Control and Revoking Consent

You are in complete control of your data. You can view, manage, or revoke our app’s access to your HealthKit data at any time by navigating to:

Settings > Privacy & Security > Health > MetricFit

Revoking consent will prevent the app from accessing HealthKit data from that point forward.

5. Medical Disclaimer

This application is intended for informational and personal health management purposes only. It is not a medical device and does not offer medical advice. The data, charts, and information presented within the app should not be used for the diagnosis, treatment, cure, or prevention of any disease or medical condition. Please consult a qualified physician or other healthcare provider for any medical advice or before making any health-related decisions.
