Privacy Policy for BMI Calculator
Last Updated: [06/09/2025]
Introduction
Welcome to the BMI Calculator app (“we,” “our,” or “us”).
Your privacy is very important to us, and this Privacy Policy explains how we collect, use, store, and protect information when you use our mobile application. We want you to feel confident that your information is safe and secure, and we are committed to complying with applicable data protection and privacy laws.
This Privacy Policy applies only to the BMI Calculator app and explains our practices in detail. Because we understand that health-related data can feel sensitive, we want to assure you that this app is designed to work without collecting, transmitting, or storing personal information on external servers. The data you enter—such as height, weight, age, and gender—is processed entirely on your device and is never sent to us.
By using our app, you agree to the practices described in this Privacy Policy. If you do not agree, please do not use the app.
1. About the BMI Calculator App
The BMI Calculator is a simple and educational tool that helps users estimate their Body Mass Index based on inputs like height and weight. It also provides general health categories (e.g., underweight, normal, overweight, or obese) based on widely accepted BMI ranges.
The app is intended for informational and educational purposes only. It does not replace professional medical advice, diagnosis, or treatment. Always consult a qualified healthcare professional regarding your health before making lifestyle changes.
2. Information We Collect
Our BMI Calculator app is designed with privacy in mind. The app does not require registration, accounts, or personal identification. However, we provide transparency on what types of information may be used or generated during app usage:
2.1 Information Entered by the User
Height (in centimeters or feet/inches)
Weight (in kilograms or pounds)
Age (to improve calculation context)
Gender (for more personalized feedback)
This information is entered manually by you and used solely to calculate your BMI. None of this data leaves your device.
2.2 Non-Personal Information
We may collect limited, non-identifiable information through the Google Play Store for analytics and crash reporting. This may include:
Device model and operating system
General app performance data
Error logs (in case of crashes)
This type of data does not identify you personally and is used to improve app stability.
2.3 No Sensitive Data Collection
We do not collect or request sensitive data such as:
Medical history
Contact information
Financial data
Location services
3. How We Use the Information
Because the app does not transmit personal data to servers, the primary use of your input is local BMI calculation. Here’s how information is used:
On-Device Calculation: Height and weight are processed instantly to calculate BMI.
Display Results: Results are shown to you within the app’s interface.
Educational Feedback: The app displays health ranges and general categories for reference.
In short: the app uses your data only for local calculations. No data is stored online, shared with third parties, or sold.
4. Data Storage & Retention
Local Storage Only: Inputs you provide may remain in the app’s memory temporarily (e.g., text fields), but they are not stored permanently in any database or server.
Automatic Deletion: Once you close the app or clear input fields, your data is erased.
No Cloud Sync: We do not back up or synchronize your data across devices.
5. Third-Party Services
The BMI Calculator is intentionally minimal and does not include intrusive third-party integrations. However, the following services may be used:
Google Play Services: Required for distribution, updates, and analytics.
Crash Reporting (Play Console): Used to improve app reliability.
These services may collect anonymous diagnostic data such as error logs or device information. We do not control how these services handle information, but you can review their privacy policies:

6. Advertising & Monetization
In its default version, this app does not display third-party ads or collect advertising identifiers. If future versions introduce optional ads, the Privacy Policy will be updated and you will be notified.
We do not sell or rent your information to advertisers.
7. Children’s Privacy
The BMI Calculator is suitable for all ages. However:
We encourage parents to supervise children when entering data.
The app does not knowingly collect information from children under the age of 13.
If you are a parent and believe your child has submitted information you wish to remove, simply uninstall the app—no data remains on external servers.
8. Security Measures
We take privacy and security seriously:
Local-only calculations: Your data never leaves your device.
No network permissions: The app does not require dangerous permissions such as camera, microphone, or location.
Google Play protections: Distribution via Google Play ensures malware checks and secure updates.
9. User Rights
Since the app does not collect personal data, there is no personal data for us to provide, edit, or delete. However, you have the following rights under general privacy laws:
The right to know what type of information could be processed.
The right to transparency regarding third-party services.
The right to uninstall the app at any time, which fully removes any locally stored inputs.
10. Changes to This Privacy Policy
We may update this Privacy Policy to reflect improvements or legal requirements. When updated:
A new “Last Updated” date will appear at the top.
Significant changes will be communicated via the Play Store app listing.
11. Disclaimer
The BMI Calculator is for informational purposes only. It should not be relied upon as medical advice. BMI is an estimate and does not account for muscle mass, body composition, or other health indicators. Always consult a healthcare professional for accurate health assessments.
We are not responsible for decisions you make based on app results. By using the app, you agree that we are not liable for any outcomes.
