This Privacy Policy explains how MeTrition ("we," "us," or "our") collects, uses, and protects your information when you use the MeTrition mobile application for iOS and Android (the "App"). We built MeTrition with a privacy-first, local-storage approach to ensure you have full control over your health data.
1. Information We Collect and How We Store It
A. Health and Fitness Data (Apple Health and Health Connect)
With your permission, MeTrition reads and writes data in your device's health platform: Apple Health (HealthKit) on iOS, or Health Connect on Android.
What we access on iOS (Apple Health): dietary energy consumed (read and write), active energy burned and basal energy burned (read), height and weight (read and write), and biological sex and date of birth (read).
What we access on Android (Health Connect): nutrition records (read and write), total calories burned (read), and height and weight (read and write). Because Health Connect does not provide sex or date of birth, you may enter them in the App instead; they are stored only on your device.
How it is used: To display your daily calorie intake, calculate your dynamic calorie goal, and log the dishes you eat.
How it is stored: Health data is read directly from and written directly to your device's health platform. We do not transmit, store, or cache your health data on our servers.
B. Local User Data
Data that you create within the App—such as your user profile (name, photo), custom ingredients, custom dishes, dish photos, and app settings—is stored entirely locally on your device in an on-device database. We do not collect or upload this data to our servers.
C. Camera and Photos
If you choose to scan a nutrition label or add a photo to a dish, the App asks for access to your camera or photo library. Text on nutrition labels is recognised on your device (Apple Vision on iOS, Google ML Kit on-device text recognition on Android). Photos and recognised text are not uploaded to our servers.
D. Notifications
If you allow notifications, the App schedules reminders locally on your device. No push-notification service or server is involved.
E. Remote Data (Restaurants & Pre-defined Dishes)
The App fetches generic information (e.g., predefined ingredients, dishes, and restaurant menus) from our servers. This connection does not transmit any personally identifiable information. Standard network request logs (like IP address and User-Agent) may be temporarily processed by our servers to return this data, but they are not linked to your personal profile or health data.
2. Analytics and Third-Party Integrations
No Custom Analytics or Tracking: We do not collect, store, or share any custom analytics, usage data, or telemetry ourselves. MeTrition does not embed any third-party analytics SDKs, crash reporters, or advertising trackers.
Platform-Provided Analytics: Apple and Google may provide us with standard, aggregated, and anonymized app performance metrics (such as crash reports or download counts) if you have opted into sharing this data with developers in your device settings. We strictly do not share any of this platform-provided analytics data with any third parties under any circumstances.
Google ML Kit (Android): On-device text recognition is provided by Google ML Kit. Recognition runs on your device and the images are not sent to Google, but Google may collect limited diagnostic and usage information about the ML Kit library itself, as described in Google's ML Kit terms.
Maps Deep Linking: If you choose to view a restaurant in Apple Maps or Google Maps, the App simply opens the respective app using a URL scheme with the restaurant's address. No personal data is shared.
3. Health Data Specific Privacy Terms
Because MeTrition integrates with Apple HealthKit and Android Health Connect, we adhere to the following strict guidelines:
We will not use or disclose health data to third parties for advertising, marketing, or other use-based data mining purposes.
We will not share or sell your health data.
On Android, MeTrition's use of information received from Health Connect adheres to the Health Connect Permissions policy, including the Limited Use requirements.
You retain full control over your health data at all times. You can modify or revoke MeTrition's access at any time in the Apple Health app settings on iOS, or in Health Connect settings on Android.
4. Data Retention and Deletion
Because your personal and custom data is stored locally on your device or in your health platform, you are entirely in control of its retention. You can delete your custom dishes or profile within the App, and you can delete all local MeTrition data by uninstalling the App. To delete health entries logged by MeTrition, you can manage them in the Apple Health app on iOS or in Health Connect on Android.
5. Changes to This Privacy Policy
We may update this Privacy Policy from time to time. If we make material changes, we will notify you within the App or update the "Effective Date" at the top of this policy.
