Privacy Policy
Effective Date: July 22, 2026 · Applies to Health Calc Hub (com.rakzlab.healthcalchub), developed and published by Rakzlab.
Health Calc Hub (“the App”) is developed and published by Rakzlab. This Privacy Policy explains how information is collected, used, and protected when you use our application.
Information We Collect
Health Calc Hub is designed to perform health calculations directly on your device. The application may collect the information you enter, including:
- Age
- Gender
- Height
- Weight
- Activity Level
- Health-related calculation inputs
This information is processed locally on your device to generate calculation results. We do not sell your personal information.
Data Storage
Calculation inputs and preferences may be stored locally on your device to improve your experience. We do not transmit your health information to our servers.
Third-Party Services
The application uses the following Google services:
- Google Play Services — required for the app to run on Android.
- Firebase Analytics — helps us understand how the app is used (e.g. which calculators are opened, app performance and crash data) so we can improve it. This data is aggregated and not linked to your health calculation inputs.
- Google AdMob — used to display ads within the app. AdMob may collect device identifiers (such as your Advertising ID), approximate location, and app usage data to show and measure ads.
These services may collect information such as device identifiers, IP address, and general usage data under their own privacy policies. You can review Google's practices in the Google Privacy Policy, and manage ad personalization at any time via your device's Settings → Privacy → Ads (or Google Settings on older Android versions).
Permissions
The application only requests permissions required for its intended functionality.
Data Security
We take reasonable measures to protect your information. However, no method of electronic storage is completely secure.
Children's Privacy
Health Calc Hub is not specifically directed toward children under the age of 13.
Medical Disclaimer
Health Calc Hub provides health-related calculations for informational and educational purposes only. The application does not provide medical advice, diagnosis, or treatment. Always consult a qualified healthcare professional before making medical decisions.

We may update this Privacy Policy from time to time. Any changes will be published on this page.
