We do not use this data for advertising or marketing purposes. It is not linked to your identity and is never sold or shared with external parties except as outlined below.
The BMI Calculator App is designed with offline-first functionality:
BMI Calculations → Inputs such as height and weight are processed entirely on your device.
History Tracking → If you use the history feature, your BMI history is saved locally on your device.

No BMI data (such as height, weight, or history) is ever transmitted to Firebase or external servers.
We integrate the following third-party services:
Google Firebase Analytics (for anonymous usage statistics)

Any unauthorized third parties
Data collected via Firebase services is handled by Google according to their terms and privacy policy.
The app is suitable for all age groups and does not knowingly collect personal information from children under 13. Since no identifiable information is collected, there is no risk of exposing sensitive data.
We follow best practices to ensure the app operates securely:
All BMI inputs and history remain stored locally on your device
Crash and analytics data are securely transmitted via HTTPS to Firebase
No sensitive health-related inputs are uploaded or shared externally
We may update this Privacy Policy from time to time to reflect changes in the App or legal requirements. Any significant changes will be communicated within the app. Continued use of the App after updates constitutes your acceptance of the revised policy.
