Privacy Policy for Health Calc

Effective Date: [18/03/2026]

Health Calc respects your privacy. This Privacy Policy explains how the app may collect, use, and protect information when you use the Health Calc app.

1. Overview

Health Calc is designed to help users calculate, track, and monitor personal health and wellness information such as body measurements, hydration, fasting progress, goals, and related metrics.

Your privacy is important, and the app is intended to limit data use to what is necessary for the app’s features.

2. Information You Provide

Health Calc may store information you enter into the app, such as:

age
sex
height
weight
body measurements
hydration logs
fasting logs
goals and preferences
calculator inputs and saved values

This information is used only to provide app functionality, personalize calculations, and help display your progress over time.

3. Apple Health Data

If you choose to connect Health Calc with Apple Health, the app may request permission to read and/or write certain health-related data.

Examples may include:

height
weight
body mass index (BMI)
body fat percentage
water intake
other supported wellness metrics

Health data accessed through Apple Health is used only to support the app’s features, such as autofilling values, saving results, and improving your tracking experience.

Health Calc does not use Apple Health data for advertising, marketing profiling, or unrelated third-party purposes.

4. How Information Is Used

Information may be used to:

perform health and wellness calculations
display saved logs and history
track fasting, hydration, and progress
support goals and dashboard features
sync supported information with Apple Health when permission is granted
improve app stability and user experience

5. Data Storage

Information entered into Health Calc is generally stored locally on your device unless a feature specifically states otherwise.

If Apple Health integration is enabled, data may also be read from or written to Apple Health according to the permissions you approve.

6. Third-Party Services

Health Calc may use Apple-provided services required for app functionality, distribution, or purchases, such as:

App Store
StoreKit
Apple Health / HealthKit
TestFlight

These services are governed by Apple’s own terms and privacy policies.

Health Calc does not sell your personal data.

7. In-App Purchases

If you purchase a premium or Pro version of Health Calc, purchase processing is handled by Apple through the App Store. Health Calc does not directly collect or store your payment card details.

8. Data Sharing

Health Calc does not sell, rent, or trade your personal information.

Information may only be shared:

when required to provide Apple-based services you choose to use
if required by law
to protect the safety, rights, or integrity of the app or its users

9. Data Retention and Control

You can control much of your data directly inside the app by editing or deleting logs and saved values.

If Apple Health integration is enabled, you can also manage Health access permissions through your iPhone settings and the Apple Health app.

10. Children’s Privacy

Health Calc is not intended to knowingly collect personal information from children without appropriate permission where required by law. If you believe information has been provided improperly, please contact support.

11. Security

Reasonable efforts are made to protect information stored and used by the app. However, no method of electronic storage or transmission can be guaranteed to be completely secure.

12. Medical Disclaimer

Health Calc is intended for informational and personal tracking purposes only. It does not provide medical advice, diagnosis, or treatment, and it should not be used as a substitute for professional healthcare guidance.
